Studying in Japan for a long period of time, such as for study abroad, working holiday, and job hunting, can be a pleasure, but at the same time, you may be worried about illness and injury.

In this article, we would like to explain the conditions for taking out a medical insurance in Japan, the types of medical insurance, insurance premiums, and procedures for foreigners who are planning to stay in Japan for a long period of time.

Is it Absolutely Necessary to have government medical insurance?

If you are covered by the government’s medical insurance, the co-payment of medical expenses to hospitals is basically 30% for people between the ages of 6 and 70. For example, when a medical cost is 10,000 yen, you can only pay 3,000 yen if you show your health insurance card to the hospital. This is the advantage of medical insurance in Japan.

In other countries, it is generally up to the individual to purchase medical insurance, but in Japan, all citizens (regardless of nationality) are required to have some type of medical insurance. In other words, all foreigners who are staying in Japan for a long period of time other than a short stay (3 months) are required to take out a medical insurance policy.

What kind of Medical Insurances are available in Japan?

In Japan, there are two types of medical insurance in general.

1.Social health insurance (Shakai-hoken)
The health insurance is for company employees in Japan.

2.National health insurance (Kokumin-kenko-hoken)
The health insurance is for housewife, freelancer, students with more than 20 years old and so on. In case of foreigners, it’s foreign students and foreigners who came to Japan on a working holiday and so on.

From now on, we would like to explain these two types of medical insurance briefly.

What is Social Health Insurance for Companies Employees?

Social insurance (shakai-hoken) consists of five components: health insurance, employees’ pension insurance, long-term care insurance, workers’ compensation insurance, and unemployment insurance, health insurance is included in this social insurance (shakai-hoken).

In Japan, full-time, contract, and part-time employees who meet the following requirements are eligible for social insurance: employees who work 20 hours a week, earn at least 88,000 yen a month and have been working for at least one year. Whenever a company hires an employee who meets certain requirements, it is obligated to have he or she joins the social insurance system.

How much is the Insurance Fee for Social Insurance (shakai-hoken) ?

The amount of social insurance fee varies depending on the area you live in, your income, and which health association you belong to. Therefore, the fees paid by a person working in Tokyo and Osaka are different.

And the payment of social insurance premiums is usually made by the company. The company deducts the monthly social insurance fee from the employee’s monthly salary, so the employee does not have to go through the payment process.

In case of employees and family members working for small and medium-sized companies who joined “Association Health Insurance” (Kyokai-kenpo), the health insurance premium rate in Tokyo from April 2020 will be 9.87% of their monthly salary as a monthly health insurance fee.

However, instead of paying the entire amount individually, the company and the individual will pay half of the insurance premiums. Therefore, half of the 9.87% of your monthly salary will be deducted from your salary as health insurance premiums.

In addition to the health insurance premiums, there are other social insurance fees such as employee pension insurance, which are generally deducted from your monthly salary.

Conclusion

In Japan, it is compulsory to purchase medical insurance so that all citizens can easily go to the hospital even for minor symptoms such as “slightly feverish” or “feeling sick”. Because of this, the amount of money that an individual actually pays at the hospital is about 30% of the total cost.

In addition, there is a system called the high-cost medical care benefits system, which sets an upper limit for monthly medical expenses based on income, so if you have a surgery or hospitalization that results in high medical expenses, you can receive a refund for any medical expenses that exceed the upper limit of your copayment.
