In order to be successful as a project manager at an IT company in Japan, you need to be familiar with the way project management is often done in Japan. Knowing how work is often done in Japan will make it easier to participate in projects, so it's a good idea to familiarize yourself with the flow and methods beforehand.In this article, we will explain the typical project management methods and techniques used in Japanese IT companies, as well as some tips for succeeding in project management in Japan. If you would like to work in project management in Japan, please use IT-related global recruitment agency “G Talent”.What is project management?In IT company project management, the following are the main things that need to be managed.BudgetSchedule and tasksAttendance of project membersIssuesSystem qualityIn addition to managing the budget, schedule and members of a project, the project manager also manages issues and system quality. The main role of the project manager is to manage the project appropriately in all aspects and lead it to success.Reference: プロジェクト管理基本のやり方／ShelterThe flow and methods of project management commonly used in Japanese companiesWe will introduce the typical flow and methods of project management in Japanese companies. By understanding the overall flow, you will be able to respond smoothly when you become a project manager.PreparationPlanningManagementClosingPreparationWhen managing a project, it is essential to make preliminary preparations to confirm the delivery date, budget, project goals, etc. You should identify the issues and tasks of the project, and assess the difficulty of the issues, how long it will take to solve them, the nature and difficulty of the tasks, and the skill level of the personnel required. It is difficult to assess the difficulty and issues without past experience or skills, so it is also important to seek the appropriate methods and opinions of experts and experienced people as necessary.Reference: 【新人PM必見】プロジェクト管理の方法とコツ／Lychee RedminePlanningOnce you have identified and carefully examined the issues and tasks, you can work out a schedule by working backwards from the deadline. When carrying out proper project management, it is necessary to create a schedule that allows you to complete the work without overworking yourself.At the same time as the schedule, it is also important to assess how many resources and personnel are needed, and what level of skill is required for the allocated personnel. If there are not enough personnel and the schedule cannot be completed within the planned timeframe, it is necessary to coordinate with other departments to get the necessary personnel to help out. If you are also planning to train junior staff, you will need to consider who you will pair up with, and who will be in charge of training them.Reference: プロジェクト管理に必要な項目と成功のポイントとは？／NotePMManagementOnce the schedule has been decided and the necessary resources have been gathered, the project will be launched and the project manager will manage the entire project. After the project has started, it is necessary to receive progress reports from the members at regular progress meetings, and to have them report promptly if any problems arise in the methods or results, etc.If manufacturing and testing have started and you receive reports on a daily basis, you may also receive reports on the progress of manufacturing and testing, the number of bugs that have occurred, etc. at the progress meeting. In addition to progress reports, it is also important to communicate closely with project members and be in a position where you can consult with them immediately about even small matters.In many projects, it is common for some kind of problem to occur. It is necessary to have a system in place where the project manager is always aware of the situation and can deal with any problems as soon as they arise.Reference: 進捗会議で何を話すのか／サル先生のプロジェクト管理入門ClosingOnce the delivery is complete and all the steps in the schedule have been completed, the project is closed. Closing is the process of reviewing the project content and results and compiling information to be used in future projects. The project manager analyzes the causes of any deviations from the original plan, why these deviations occurred, what went well and what did not, and summarizes the results. For the next project, it is also necessary to summarize the areas that should be reflected on and the areas that should be utilized in the next project.Reference: プロジェクトや工程終了時に行う７つのポイント – プロジェクト・フェーズ終結／プロマネ研究室Common Project Management Methods in JapanFrom here, we will introduce some of the specific methods of project management commonly used by Japanese companies. By becoming familiar with the methods introduced here, you can reduce the chances of being confused when managing projects for the first time at a Japanese company.Gantt chartWBS (work breakdown structure)CCPMWaterfall developmentPERT diagramAgile developmentGantt chartThe Gantt chart is the oldest method of project management. It is managed in a format similar to Excel, with tasks lined up in order from the top row, and the number of days passes as the columns move to the right.A bar is set for each task, with the left edge being the start date of the task and the right edge being the completion date. The upper and lower bars are divided into the planned and actual, and as progress is made, the actual fills in.The tasks are arranged in a staircase-like pattern, and it is easy to see at a glance how much the planned and actual progress deviate from each other. However, there are also disadvantages, such as it being difficult to understand the relationship between tasks and it being difficult to respond to major schedule changes.Reference: ガントチャートって何ですか？／ITmediaWBS (Work Breakdown Structure)WBS (Work Breakdown Structure) is a method of breaking down tasks into smaller tasks and creating a schedule for them. For example, in the testing process, it is necessary to set the perspective, identify items, prepare for reviews and testing environments, create test data, conduct tests, and check the results. Once the necessary tasks have been identified, the schedule for the tasks is decided and implemented.By using this method, you can identify what needs to be done to reach the goal and how much work will be involved. However, it also has some disadvantages, such as being subjective and making it difficult to break down tasks.Reference: WBS（作業分解構造図）とは？ガントチャートとの違いや作り方を基礎から解説／マイナビクリエイターCCPMThis method, known as Critical Chain Project Management, is often used for large-scale projects, and is a method of minimizing tasks and budgets and allowing for a buffer in the schedule.It is said that when deadlines for work are set, people often do not start work until the very last minute, so by setting a deadline with a buffer rather than a true deadline, you can eliminate waste and shorten the schedule. However, if an inexperienced manager uses this method, they may end up taking too much of a buffer and creating an unrealistic schedule, so it is a method for experienced managers.Reference: CCPM（クリティカルチェーン・プロジェクトマネジメント）とは？大型プロジェクトにはCCPMを取り入れよう／株式会社システムイングレータWaterfall developmentWaterfall development is a method of arranging processes in order, like the flow of water, and has been used for a long time. For example, the project schedule is made up of the following stages: requirements definition, external design, internal design, manufacturing, testing, delivery, and operation.Waterfall development is often used for large-scale projects where the schedule and work content remain largely unchanged. In the case of large-scale systems where functions are added repeatedly, the project stages remain largely the same. If the work process is established, it is easy to make a schedule and to steadily carry out the project.However, it is not suitable for projects where the schedule is difficult to change, where a major problem occurs and the plan goes awry, or for short-term projects.Reference: ウォーターフォール開発とは？メリットとデメリットを解説。ほかの開発手法も紹介！／発注ラウンジPERT DiagramA PERT diagram is a chart that shows the order of tasks and work within a project. PERT diagrams show tasks, work times, work start dates and work end dates, and the order of each task is shown using arrows. It is suitable for complex work orders, such as when work on C can begin after work on A and B is complete, or when work on D and C is not sequential, but work on E cannot begin until C is complete.Reference: PERT 図とは？仕組みや作成方法を徹底解説／asanaAgile developmentAgile development is a method of project management that repeats processes in short periods of time called “iterations”. It is the opposite of waterfall development, where the entire process is decided from the start, and the process is repeated many times.For each iteration, plans and goals are set, and the process is repeated in a short span of time, with the issues and results from each iteration being immediately applied to the next. It is possible to carry out flexible and speedy development while repeatedly changing the specifications. However, it will be difficult to carry out a project without problems using this method unless you have experienced and knowledgeable managers.Reference: アジャイル開発とは？　特徴とメリット・デメリット、スクラムまで徹底解説／Monstarlab Blog5 Tips for Successful Project Management in Japanese CompaniesFrom here, we will explain some tips for successful project management in Japanese companies.Look over the PMBOKUtilize management toolsSetting milestonesCarry out risk managementEmphasize communicationLook over the PMBOKThe PMBOK is a kind of reference book that summarizes knowledge about project management. The PMBOK is the world standard for project management, so it can be used not only in Japan but also in any country where project management is carried out.In some cases, knowledge of the PMBOK is required when hiring a project manager. If you have a good grasp of the PMBOK, it will be useful when carrying out project management work in any country.Reference: PMBOKとは？プロジェクト達成のための世界標準知識を学ぼう／インターネットアカデミーUtilize management toolsTo carry out project management smoothly, let's actively use management tools. We recommend tools that have all the functions a project manager needs, such as progress management, information sharing with team members, file sharing, and attendance management. If you manage manually using Excel or other software, it is easy to make mistakes or forget things, and it will take a long time. Using a management tool can be expected to improve the efficiency of management work.Setting milestonesWhen managing a project, it is important to always be aware of the milestones. Setting detailed milestones, such as checking the direction of the work in progress as well as the deadline for the entire task, can help to prevent delays in progress and also to check the work. Setting specific deadlines for answering questions and submitting materials can also help to prevent them from being neglected.Reference: マイルストーンとは？意味や使い方を解説！中間目標の設定でプロジェクトを成功させる！／JootoマガジンCarry out risk managementRisk management is extremely important for project managers. For example, if the schedule is tight, you will need to take action such as making arrangements to get people from other departments to help out. Be prepared so that you can deal with anything that happens.Reference: プロジェクトにおけるリスク管理とは？手法やプロセスについて解説します／JootoマガジンEmphasize communicationIn order to succeed in project management, it is essential to share information and communicate with team members. It is important to actively communicate with team members, rather than just waiting for them to report.If the atmosphere is such that team members are unable to raise issues, the problems may not be discovered until they have grown in scale, and the damage may be significant. Make sure you communicate with your team on a regular basis so that you can talk to them quickly when they raise their hand.Let's find a Japanese IT company that suits you and work in project management!In this article, we have explained the typical flow of project management in Japanese IT companies, the methods commonly used, and tips for succeeding in project management in Japan. Project management is a very important element for ensuring project success.

They have experience in supporting the recruitment of over 200 companies and engineers from over 70 nationalities, and they have many jobs registered that will allow you to work as a project manager, so you are sure to find a job that suits you.

There are cases where the way web development is done differs between Japan and other countries. In order to work as an IT engineer in a Japanese company, it will be easier to do your job if you know about the methods and approaches to web development commonly used in Japanese companies, as well as the knowledge and programming languages commonly used in Japanese companies.What are some of the methods commonly used in web development in Japanese companies? In this article, we will explain the common methods of web development used by Japanese companies, the knowledge required, and the programming languages commonly used by Japanese companies. By reading this article, you will be able to obtain the information you need to carry out web development at a Japanese company. If you would like to work as an IT engineer in a Japanese company and be involved in web development, please use the recruitment agency “G Talent”, which brings together global companies in the engineering industry.What is web development?Web development is one of the most common types of engineering work in Japan and around the world, and involves the development of systems such as web services, web apps and web software. Nowadays, it is becoming more common to use web-based systems such as web services and cloud services. Because they are low-cost and highly convenient, there is a growing demand for web-based developers over on-premise systems and software developers.Along with the growing demand for web developers, there is also a growing demand for web engineers in Japan. There is a shortage of IT-related personnel in Japan, including web engineers, and there is also a high demand for foreign web developers. If you are a foreign engineer and you want to work on web development in Japan, it is important to know about the common ways of doing web development in Japan.Reference: Web開発とは？Web開発の流れや必要な準備について解説！／発注ラウンジ[7 Steps] Common web development methods in Japanese companiesFirst of all, we will introduce common web development methods in Japanese companies. There are a total of 7 steps, so let's get to know the general development flow and the content of each step.Requirement definitionExternal designInternal designDevelopmentTestingReleaseOperation and maintenanceRequirement definitionRequirement definition is the process of clearly defining the necessary functions and requirements before starting a project. The website's design, what you want to achieve, what kind of output is needed, etc. are all defined in detail, and a document is created that summarizes these requirements.Once the requirements have been more or less finalized, the necessary budget, personnel, project period, etc. are also decided at this stage. In Japan, it is often the case that a solid plan is made at the beginning of the requirements definition process. For this reason, it is said that the schedule tends to slip and work becomes tight the further along the process goes.Reference: システム開発の「要件定義」とは？進め方やコツを解説／発注ラウンジExternal designExternal design is the system's basic design stage, in which screen design, input/output specifications, etc. are designed based on the functional and performance requirements and constraints, etc. specified in the requirements definition document. In addition to the external design of functional requirements, it is also necessary to design the external design of performance requirements such as the number of users, number of accesses, and response time.The external design is carried out while carefully checking to ensure that there are no omissions in the requirements. If there are omissions at this stage, it will cause major rework later on, so it is important to carry out the work in a reliable way. If a system is created with an incorrect design, it will have to be redone from the design stage, so the design is repeatedly reviewed to ensure that there are no omissions or mistakes.Reference: 外部設計書と内部設計書の違いとは？作成ポイントまで解説！／株式会社システムイングレータInternal designInternal design is the internal design work that is not visible from the outside, such as deciding what language and development environment to use, how to process data, and how to structure the system. It is necessary to clearly define the details, such as the internal operation of the system and the structure of the database. The system must be designed with lean processing and structure so that it can also meet the performance requirements.DevelopmentBased on the external and internal designs, this is the stage where the coding is implemented and the system and programs are developed. High-quality programs must be created while making full use of the programming languages that correspond to the system and programs.In Japanese companies, it is common for development to be outsourced to subcontractors on a module-by-module basis. When outsourcing to subcontractors, it is necessary to hold thorough discussions with the subcontractors to ensure that there are no gaps in understanding. Depending on the subcontractor, there may be differences in approach, so it may be necessary to iron out any differences during the discussions.Reference: WEBシステム開発のプロセス、プログラミング言語、費用などを解説／GALKTestingThe testing process is an essential part of web development. Testing helps to avoid problems and security risks, and also allows you to check that the system has been developed as per the requirements. The testing process is divided into several stages, including unit testing for each module, integration testing where modules are combined, system testing where the system is run from the user's perspective, and operation testing where the system is checked for operation in the actual client environment. It is essential to complete all tests, and bugs are collected as necessary based on the results of the tests.Reference: Webアプリのテスト工程とは？テストの内容と工数について解説／株式会社DesafiosReleaseOnce steps from 1 to 5 have been completed, it is time to release the completed program to the client's system environment. There are three common patterns of release work in Japanese companies: simultaneous migration, where all programs are released at once; sequential migration, where programs are released gradually in stages; and parallel migration, where the old and new systems are run simultaneously for a certain period of time before being gradually switched over. The method used for migration will depend on the system, the content of the program, and the company.Reference: システムリリースを成し遂げるには？／エンジニアの入り口Operation and maintenanceOnce the release has been completed without any problems, the final stage is the operation and maintenance process. The content of operation and maintenance work that is often carried out by Japanese companies includes monitoring to check that the program is running without any problems, daily and monthly maintenance, changing settings as necessary, and dealing with problems. There are also cases where you have to respond to inquiries from end users of the system.Reference: ソフトウェア・システムの「開発」「運用」「保守」の3つの仕事内容とは／Hybrid technologiesKnowledge and skills required for web development, which is common in Japanese companiesThe following three are the knowledge and skills required for web development, which is common in Japanese companies.ProgrammingFrameworksDatabasesProgrammingProgramming is a skill that is required not only when programming in the development process, but also when in charge of the design or testing process. Common ways of using it include when reviewing programs as a designer, or when checking the modified parts of a program when a bug occurs in testing. Of course, advanced programming skills are required when programming. If you have a lot of work experience in the language you are using, you will be able to do a better job.If you have skills such as being able to use advanced development environments and develop tools, you will be in high demand as a web developer. Being able to use advanced development environments has the advantage of being able to speed up compilation and detect program errors. By developing your own tools, you can also automate program checking, automatic debugging, program management, and automatic test data generation.Reference: Web開発とは？Web開発をするために必要なスキルやフローを解説／Geekly MediaFrameworksBy mastering frameworks, you can develop high-quality programs efficiently, so knowledge and skills in frameworks are necessary when programming in the development process.A framework refers to a set of pre-made source code that exists for each programming language. When developing a system, there are common functions that are used in many systems, such as login authentication, input forms, network communication, and payment functions, and by utilizing frameworks that have already been created for such functions, it is possible to efficiently develop high-quality programs.There are frameworks for each programming language, such as Ruby on Rails for Ruby and CakePHP for PHP. If you learn the framework for the programming language you use in the workplace, you will be able to program at a high quality.Reference: フレームワークとは？概要やプログラミング言語別の機能を分かりやすく解説／レバテックルーキーDatabasesIn order to be active in web development at a Japanese company, you will also need knowledge and skills related to databases. In almost all cases, databases are used in any system. You will need to design and develop databases that store data such as customer data and transaction histories, and make them easy to access. Along with programming languages, you should also acquire the skills to develop and operate databases.Reference: 【Web開発の基本】初心者が知るべき重要な概念／QiitaThe main languages used in web development at Japanese IT companiesFrom here, we will introduce the languages that are often used in web development at Japanese companies.HTML, CSSJavaScriptPHPPythonJavaTypeScriptRubyHTML, CSSHTML and CSS are essential for web development. HTML is a language used to write web pages, and it can be used to create text, images, paragraphs, page structure, etc.CSS is a language used to set styles for pages written in HTML. It can be used to specify font size, font, color, etc. There are also development environments that can automatically generate HTML and CSS, so if you make good use of these, you can develop efficiently. When working on web development, you will need to understand the syntax of HTML and CSS, as you will sometimes need to look at the source code itself to make improvements or find problems.Reference: HTML/CSSとは？初心者向けの基礎知識と学習サイト5選／SAMURAI ENGINEER BlogJavaScriptJavaScript is a language used to create dynamic screen movements. For example, moving the mouse on the screen to make an animation appear is something that can only be achieved with JavaScript. Many websites and web apps now use animated features, and JavaScript is used for all of these. JavaScript is used frequently, so it is a language that web engineers must learn.Reference: JavaScriptとは？基本的な書き方や勉強方法～入門～／AKKODiSPHPPHP is a programming language developed for website creation, and it can be used to develop all kinds of website elements. As it is not the latest programming language, there is a good chance that it will be overtaken by other languages in the future.However, there are already many websites that have been built using PHP, and there are many opportunities to use it for adding functions and operational tasks. For this reason, it is one of the languages that web engineers should learn.Reference: PHPとは？基礎知識、できることを初心者にもわかりやすく解説します／カゴヤのサーバー研究室PythonPython is a language that is used not only for website construction, but also for AI field development. It is used in AI development, automatic data processing, analysis, etc., but it can also be used for web service and web app development.

In order to be successful as a backend engineer in an IT company, you will need a wide range of skills and knowledge. In particular, knowledge of languages is essential for backend engineers, and there are many different types of languages, so you may be wondering which one you should focus on. The languages required for backend engineers change over time, and also depend on what kind of system development you are working on.In this article, we will explain the languages that backend engineers should focus on, the languages that they should learn in the future, and the future prospects for backend engineers and what they need to do to be successful. If you want to work as a backend engineer in Japan, we recommend “G Talent”, a recruitment agency specializing in global IT companies.What is a backend engineer working at an IT company?The term "back-end engineer" refers to an engineer who develops server-side programs for web pages and web applications. Websites and web pages have two types of programs: the front-end, which is the program that users can see on the screen, and the back-end, which is the program that users cannot see.The back-end program handles processing requests from the front-end and database operations. For example, the role of the backend is to authenticate users by checking their login information against the database, and to output customer data by referring to it. Backend engineers are the ones who develop backend programs like this.On the other hand, frontend engineers develop the frontend programs that users see on the screen, using HTML, CSS, etc. They are responsible for executing the frontend programs, such as moving animations on the screen and outputting input forms.Back-end engineers and front-end engineers have different roles and objectives, so the knowledge and skills they need to focus on are also different. In this article, we will take a closer look at back-end engineers, who work on the programs that are not visible to users.Reference: バックエンドエンジニアとは？フロントエンドエンジニアとの違いや求められるスキルについても解説／AKKODiSLanguages that back-end engineers in IT companies should focus on from now onThere are many different types of languages used by engineers, and many people may be wondering which languages they should focus on in order to become active as a backend engineer at an IT company in the future. Languages in high demand for backend engineers should be prioritized for learning, and it is also recommended to learn languages that are expected to develop in the future. In this article, we will introduce four languages that backend engineers should focus on in the future.PythonPython is a programming language suitable for engineers working with deep learning. Back-end engineers who want to work in fields such as AI and machine learning in the future should learn it. Python is a language that can also be used for developing web apps, games, desktop apps, etc. However, for back-end engineers who do not work on AI or machine learning, it is not a language that should be mastered as a trend.Even among backend engineers, if Python has already been introduced in the workplace or is included in the requirements for job postings, you should hurry up and learn it. If you need deep learning skills, we recommend that you consider learning it.Reference: Pythonでできること一覧！AI・データ分析など事例をふまえて解説／UdemyメディアGoGo is a relatively new language, and it is increasingly being used for back-end development. Compared to Java and Ruby, the way you code is very different, so the learning curve is steep, but the advantage is that you can do it with less coding, so it's compact and less prone to bugs. Go is a language that is expected to develop in the future, so it is recommended that you learn it if you want to work as a back-end engineer at an IT company in the future.Reference: Goエンジニアの仕事内容は？将来性や身に付けるべきスキルについて解説！／HiPro TechKotlinKotlin is a relatively new language that is Java-based and suitable for Android development. If you are a backend engineer who wants to start developing Android apps, we recommend learning Kotlin. Although the iPhone has a large share of the smartphone market in Japan, Android is dominant worldwide. Demand for Android app development is expected to remain high in the future, so if you are planning to develop apps, you should learn Kotlin.Reference: Kotlinのこれからを語るScalaScala is a new language that is compatible with Java and has many advantages, such as high-speed processing and high development efficiency. It can be used for server-side development and development related to big data analysis, so it is a language that is set to develop in the future. As the successor to Java, it is highly secure and can be used for large-scale systems. For this reason, it is one of the languages you should learn if you want to work as a backend engineer for an IT company in the future.Reference: Scalaとは？将来性やメリット・デメリット、Javaとの関係も解説／レバテックキャリアLanguages that back-end engineers in IT companies should knowThe four languages introduced above are relatively new languages that back-end engineers should know. From here, we will also introduce the five standard languages that back-end engineers often use.PHPPHP is a language that is active as a back-end development language. There are many existing systems that have been developed in PHP, and it is often necessary to use PHP when performing system maintenance or adding functions. However, PHP is not a trendy language, and it is expected that it will gradually give way to new languages that will become major in the future. However, there are many IT jobs that require PHP skills, so it is one of the languages you should learn if you want to work as a backend engineer at an IT company in the future.Reference: 2000年以降20年間のプログラミング技術の歴史を振り返って、得た知見を書いてみる／QiitaJavaJava is a basic language that should be learned as a top priority for back-end engineers. It is used all over the world because it is highly secure and can reduce bugs and security risks, and there are many parts that are necessary for working with existing systems. If you learn frameworks such as Spring and Spring Boot together, you will be able to code efficiently.Although Java is an old language that is rarely upgraded, there are still many job postings that require Java skills. If you are looking to change jobs and increase your annual income, we recommend learning it.Reference: バックエンドエンジニアになるには（身につけるべき重要なスキル）／kinstaRubyRuby is a language developed in Japan and is the base language for the popular framework Ruby on Rails. Using it in conjunction with this framework makes programming easier and allows for more efficient development. It is a language that is constantly evolving, so it can be said that it will continue to play an active role in the future. It is particularly often used by venture companies, so back-end engineers who are aiming for jobs at venture companies should learn it.Reference: プログラミング言語のRubyとは？特徴やできることを解説／発注ラウンジC, C++The C language, which has been used for a long time, is a general-purpose language that can be used for developing operating systems, core systems, software, embedded systems, etc. C++ is an object-oriented language that extends the C language, and can be used for a wide range of applications, including web apps, embedded systems, AI development, and game development. There are many systems that run on these languages, and there are still many system maintenance and function addition projects. For this reason, you should make sure you have a good grasp of these languages as a backend engineer.Reference: C言語は今でも価値のある言語か？／InfoQC#C# is a language that is very similar to Java, and it can be used for web apps, smartphone apps, game development, etc. As it was developed by Microsoft, it has a high affinity with Microsoft products. There are many existing systems that are running on C#, so it is one of the languages that you should know as a backend engineer.Reference: C#の将来性はある？需要が高まっている理由や成功するための方法を紹介／HiPro TechWhat is the future for IT companies as a backend engineer?There are many different types of engineers in IT companies, and I'm sure many people are wondering what the future holds for backend engineers. Backend engineers' jobs, such as maintaining and operating existing systems, will never disappear, so it can be said that this is a job that will continue to be in demand. In fact, there are many job openings for adding functions to existing systems, fixing bugs, and maintenance, and it is predicted that the high demand for backend engineers will continue in the future.Furthermore, the market for IT systems and smartphone apps is expected to continue growing, so the demand for backend engineers is extremely high. However, the skills required of backend engineers are constantly evolving, so you need to constantly acquire new skills and knowledge.Reference: バックエンドエンジニアの今後は？予想される5つと必要とされ続けるためのスキルを解説／DMM WEBCAMPIt is a chance for foreign IT workers to work as back-end engineers in Japan!In recent years, the shortage of IT workers in Japan has continued, and the number of foreign IT engineers has been increasing in order to make up for the lack of human resources. According to the Ministry of Health, Labour and Welfare's “Summary of Reports on Employment Status of Foreigners” (as of October 31, 2021), the number of foreign workers has continued to increase as shown in the following graph. In particular, in Japan's IT industry, where the shortage of human resources is progressing, there is a high possibility that demand for foreign IT engineers will continue to grow. For foreigners who want to play an active role in Japan from now on, it can be said that backend engineering is one of the recommended occupations.What is necessary to play an active role as a backend engineer at an IT company?In order to play an active role as a backend engineer at an IT company from now on, you will need various knowledge and skills in addition to programming languages. In particular, the following five things are things that you will not lose by remembering as a backend engineer.Improve management skillsImprove framework skillsAcquire cloud skillsAcquire knowledge of securityAcquire front-end skillsImprove management skillsWhen working for a Japanese IT company, team work is required in almost all workplaces. In particular, if you want to become a leader or manager rather than just a worker as a team member, you will need management skills to ensure that work is carried out smoothly within the team. As you will need to communicate with team members, manage progress, manage problems, and train junior staff, you will need to develop high-level management skills.

The main role of front-end engineers working in IT companies is to develop the screen interface that users can see. Engineers, not just front-end engineers, need to be able to use programming languages, and there are also programming languages that are suited to front-end engineers.What kind of language knowledge and skills should front-end engineers working for IT companies acquire in order to be successful in the future? In this article, we will explain the programming languages and frameworks that front-end engineers should learn in order to be successful in the future, as well as the future prospects for front-end engineers and what they need to do in order to be successful.If you are looking for a job as a front-end engineer at an IT company, please use IT engineer-focused recruitment agency “G Talent”.What is a front-end engineer working at an IT company?A front-end engineer working at an IT company is an engineer who develops the parts of websites and web apps that users can see. They use various programming languages to create screen designs and movement exactly as the web designer has designed.In addition to front-end engineers, back-end engineers are also needed for the development of websites and web apps. The back-end is the part of the program that runs on the server in response to requests sent from the screen to the server. The job of back-end engineers is to develop programs on the server that are not visible to users.Front-end development is an important part of developing websites and web apps that users use. High-quality front-end engineers are essential for creating easy-to-use, easy-to-view, high-functionality websites and web apps. As the number of websites and web apps is expected to continue to increase, demand for front-end engineers is also expected to remain high.Reference: フロントエンドエンジニアの将来性と求められるスキル・資格を解説／レバテックキャリアProgramming languages that front-end engineers at IT companies should focus on from now onFrom here, we will explain the programming languages that front-end engineers who want to become active in the future should learn, as well as frameworks that make programming languages easier to use. We will introduce programming languages and frameworks that are likely to develop in the future, so if you come across any you don't know, make sure you get to grips with them. If you want to become even more active as a front-end engineer from now on, please make sure you refer to this.PHPPHP is not a programming language of the future, but a general programming language that IT engineers should know. PHP is used mainly in the back-end, but it is also a major language used in services such as WordPress, so it is expected that front-end engineers will have more opportunities to use it in the future.Some companies need engineers who can build and customize WordPress, so learning PHP is recommended to be able to handle a wide range of work. Because its syntax is simple, it is one of the languages that is relatively easy to learn.Reference: PHPとは？基礎知識、できることを初心者にもわかりやすく解説します／カゴヤのサーバー研究室TypeScriptThis is a programming language that allows type declarations and was developed by Microsoft as an extension of JavaScript, a standard programming language for front-end engineers. By declaring types, you can prevent errors when compiling the source code, so it has the feature of improving development efficiency. Compared to JavaScript, it has the advantage of reducing the occurrence of bugs and allowing you to develop safely and efficiently.Development using TypeScript is becoming mainstream, and there is also a movement to rewrite JavaScript code in TypeScript. For this reason, it can be said that it is a language that should be mastered as a front-end engineer.Reference: TypeScriptを入門者向けに解説！JavaScriptとの違いや勉強法までわかりやすく／Udemy mediaNext.jsNext.js is a framework developed based on React.jp. React.jp is a library used when developing user interfaces in JavaScript, and it is effective for efficient development in JavaScript. Using Next.js makes it possible to increase the efficiency of web app development.The biggest difference between Next.js and React.jp is the presence or absence of server functions. Next.js has server functions, so you can run web apps on their own, and it has the advantage of easier environment preparation and lower learning costs than React.jp. Using Next.js allows you to develop efficiently in JavaScript, so it is recommended for those who want to become active as front-end engineers in the future.Reference: Next.jsとは？Reactとの違いやインストール・基本操作を解説！／Udemy mediaNuxt.jsNuxt.js is a JavaScript framework based on Vue.js. Vue.js is also a JavaScript framework like React.js, and it has many advantages, such as components that can be used like program components and extensibility that allows the use of plugins. Nuxt.js is a more user-friendly version of Vue.js, and it is possible to greatly improve development efficiency.While Vue.js does not have a server function, Nuxt.js does, so Nuxt.js is easy to use without the hassle of installing server libraries, etc. For this reason, we recommend that front-end engineers who want to become active in the future learn Nuxt.js.Reference: Nuxt.jsとは？Vue.jsとの違いやできること、メリットを解説／TECH MANIASvelte.jsSvelte.js is a JavaScript framework that is not as major as React.js or Vue.js, but it is expected to develop in the future.While React.js and Vue.js are classed as libraries, Svelte.js is a compiler. It works by compiling files with the extension “.svelte”, which contain source code written in HTML, CSS and JavaScript. Using Svelte.js has the advantage of reducing the amount of code you have to write and making it less likely for bugs to occur. It has a full range of functions, so it can be said to be a framework that is suitable for small-scale development.However, since Svelte.js is a new framework that is still in its infancy, there is not a lot of information available, and it may be difficult to learn. It is not suitable for large-scale development because it has low extensibility and few functions. While keeping in mind the points to note, learn it if it will be useful for your own development work.Basic languages that front-end engineers in IT companies should knowUp to this point, we have introduced languages and frameworks that are likely to develop in the future for front-end engineers. However, of course, in order to be active as a front-end engineer, you also need to have basic knowledge of languages. From here, we will explain the basic languages that you should learn when working as a front-end engineer.HTMLHTML is a fundamental development language that is essential for front-end engineers. HTML is a markup language that is essential for developing web pages, and it plays a role in giving computers instructions on how to structure and provide information such as text and photos when creating websites.Because it is not possible to create or update websites without specialist knowledge of HTML, it can be said that it is a language that front-end engineers must definitely master. The current latest version of HTML is HTML5, so you should upgrade to this version if you are using anything else.Since HTML is almost always developed using HTML editors and other development tools, there may be few cases where you have to generate and write tags yourself. However, since you may have to read code and make improvements or extensions, it is necessary to learn the HTML language.Reference: HTMLとは？CSSとの違いやメリット・デメリット、代表的なタグについても解説／生涯学習のユーキャンCSSCSS is also called a style sheet, and is used in conjunction with HTML to develop web pages. HTML is essential for web pages, but beautiful visuals cannot be created using HTML alone. By creating the page's document structure using HTML and setting the font color, font size, etc. using CSS, the web page will become easier to read. When learning HTML, also learn CSS at the same time.As with HTML, CSS is increasingly being generated automatically in development environments, so there may not be many cases where you have to code from scratch. However, as you will need to decipher the source code, you will need to understand the syntax and structure if you want to work as a front-end engineer.Reference: CSSとは？基本的な書式や書き方、学習のポイントなどを解説／／生涯学習のユーキャンJavaScriptJavaScript is a language for building dynamic web page functionality. For example, it can be used to achieve dynamic on-screen functionality such as starting an animation when the mouse cursor is moved on the screen, or making images slide one after another. Because this kind of dynamic web page functionality is used on many websites, JavaScript is a language that is essential for front-end engineers.In order to do a good job as an engineer, you need to use libraries and frameworks to carry out efficient, high-quality development, rather than just using JavaScript. The frameworks introduced above can all be used with JavaScript, so it's a good idea to learn them as necessary.Reference: 【初心者向け】JavaScriptとは？基本の書き方をわかりやすく解説／HubSpotWhat is the future for front-end engineers in IT companies?If you want to work as a front-end engineer in an IT company in the future, you will be wondering about the future prospects for this career. Although it is difficult to say with certainty about the long-term future prospects for front-end engineers over the next few decades, it is a career that is said to have short-term prospects.The use of the internet and the spread of smartphones and tablets is continuing to expand, and demand for website and app development is expected to continue to expand in the future. For this reason, it is expected that the work of front-end engineers involved in websites and web apps will continue to increase in the future.However, when considering the next few decades, it is unknown how the work of front-end engineers will change due to improvements in technology such as AI. In the future, there is a possibility that new engineers other than front-end engineers will be born, as more advanced technology and knowledge than now may be required.Reference: フロントエンドエンジニアの将来性と今後の展望を解説／HiPro TechChances for foreign IT engineers to work in JapanThe number of foreign IT engineers is increasing in Japan. According to the Ministry of Health, Labour and Welfare's “Summary of Reports on Employment Status of Foreigners” (as of October 31, 2021), the number of foreign workers is continuing to increase as shown in the graph below.In particular, there is a shortage of IT personnel in Japan, and demand for foreign IT engineers is increasing. For this reason, it can be said that the environment is becoming more conducive to foreign engineers working as front-end engineers. If you want to work as a front-end engineer in the future, consider working in Japan, where there is a shortage of personnel.What you need to do to work as a front-end engineer in the futureIn order to work as a front-end engineer at an IT company in the future, you will need to acquire the following skills, as well as language skills.Improve management skillsImprove UI/UX design skillsGain knowledge of web marketingGain knowledge of back-end engineeringImprove management skillsAs a front-end engineer in an IT company, you will be working with many team members to progress with development, so you will need to improve your management skills. If you only work as a worker, you will not be able to do a good job as a team. In order to cooperate with each other and progress with development while efficiently dividing up the work within the team, you will need excellent management skills.If you can improve your management skills by sharing the workload within the team and managing the progress of development, as well as dealing with any problems that arise, you will definitely be able to make the most of your skills as a front-end engineer in the future.Reference: フロントエンジニアの需要は無くならない？今後の将来性と求められるスキルとは／DMM WEBCAMPImproving UI / UX design skillsFront-end engineers who create highly visible web pages and web apps also need UI design skills and UX design skills.The UI of a website refers to the appearance and ease of use of the site. If the UI design is poor, it can cause users to become disengaged, so UI design is an important aspect of a site, as it is the face of the site. UX design refers to the experience that users gain through web pages. It refers to the kind of experience users have and the impression they form of that experience, and if they have a positive impression of the experience, it means that the UX evaluation is high.UI design and UX design can be acquired by gaining work experience while studying knowledge and skills. In most IT companies, there is a high demand for front-end engineers with strong UI and UX design skills who can create high-value web pages.Reference: 今さら聞けない！ UI（ユーザーインターフェース）とは？／M-HAND BLOGGain knowledge of web marketingWeb marketing, also known as SEO, is a strategy for ensuring that your company's website appears at the top of search results when people search for keywords on search engines such as Google and Yahoo! No matter how good your website is, if it doesn't appear in the search results for many people, it won't be accessed.For this reason, front-end engineers also need to acquire knowledge and skills related to SEO for web marketing activities. In some IT companies, SEO may be included in the job description of front-end engineers, so if you have knowledge of web marketing, you will be recognized as a front-end engineer who can make an immediate contribution.Reference: フロントエンドエンジニアの仕事内容とは？未経験からの転職は簡単なのか徹底解説／パーソルクロステクノロジーGain knowledge of back-end engineeringBy acquiring not only front-end engineer knowledge but also back-end engineer knowledge for server-side program development, your demand as a front-end engineer will increase.
