4.9 Japan's social security system

Japan has a universal insurance system whereby everybody residing in Japan must, in principle, take part in the public health (medical) insurance and pension insurance system.

4.9.1 Labor and social insurance systems

Japan has four different kinds of insurance system which companies are legally obliged to take part in; all workers that meet certain criteria are covered by the insurance.

  1. (1)

    Workers' Accident Compensation Insurance

    This covers any illness or injury at work or while commuting to or from work.

  2. (2)

    Employment Insurance

    This provides for workers that become unemployed and helps to maintain stable employment such as by providing financial aid and subsidies.

  3. (3)

    Health Insurance and Nursing Care Insurance

    These cover medical and nursing care expenses incurred by workers.

  4. (4)

    Employees' Pension Insurance

    This provides benefits for old age, death or disability.

Generally, Workers' Accident Compensation Insurance and Employment Insurance are known collectively as "labor insurance," while Health, Nursing Care and Employees' Pension Insurances are referred to collectively as "social insurance."

A company must enter these insurance systems when first incorporating or hiring staff/workers by submitting labor and social insurance notification forms to the relevant authorities. The company usually pays insurance premiums by deducting the portion of the premiums payable by employees/workers from their wages, and paying these together with the portion of the premiums payable by the company to the relevant authorities.

Also, from April 2020, corporations, mutual companies, investment corporations, and special purpose companies with share capital or owners’ equity exceeding 100 million yen are required to file procedures for social insurance and labor insurance electronically as a general rule.

4.9.2 Workers' Accident Compensation Insurance

(Table 4-5) Overview of Workers' Accident Compensation Insurance
Application As a rule, this is compulsorily applicable to all workers. However, some workers such as officers of corporation or relatives living together may not be applicable. Principals of small and medium businesses (representative director, etc.) may be specially approved for coverage if they apply.
Benefit Benefits are paid for any illness, injury, disability or death incurred as a result of an accident caused by a work or while commuting to or from work.
Premium Premiums are generally calculated as a certain percentage of total amounts of each worker’s wage. Premium rates depend on the kind of business carried out at the workplace; the maximum premium rate is 8.8% (for metal/non-metal/coal-mining industries) and the minimum is 0.25% (for finance, insurance telecommunications and broadcasting industries) (revised in April 2024). The employer bears the whole cost of premiums.
0.002% is added to the above premium to fund benefits for asbestos-induced diseases.
Notification Notifications shall be submitted to the local Labor Standards Inspection Office within a period of 10 days starting on the day following that on which participation in the insurance program was established.

4.9.3 Employment Insurance

(Table 4-6) Overview of Employment Insurance
Application In principle, this applies to all general workers. However, to qualify for Employment Insurance, prescribed working hours must not be less than 20 hours per week, and they must expect to be employed for not less than 31 days. Employees dispatched to Japan from an overseas company head office who enroll in a scheme equivalent to employment insurance overseas are exempt from this insurance.
Benefit Benefits are paid for a predetermined period when the insured worker leaves his/her job; the amount of benefits are determined according to the reason for leaving the job, the length of time for which the insured was covered, the insured party's age, etc. There are also a number of benefits available for the purpose of maintaining stability of employment.
Premium Premiums are calculated as a certain percentage of each worker’s total wage. The insurance premium rate is 1.55% (the employer paying 0.95% and the worker paying 0.6%) with the exception of a few kinds of job (revised in April 2023).
Notification Notifications must be submitted to the local Public Employment Security Office within a period of 10 days starting on the day following that on which participation in the insurance program was established.

4.9.4 Health Insurance and Nursing Care Insurance

(Table 4-7) Overview of Health Insurance and Nursing Care Insuarnce
Application:
Applicable businesses
All incorporated companies without exception and a representative office which has 5 or more regular employees and falls under the prescribed kinds of businesses are obliged to take part in the insurance. Branches and sales offices of overseas companies are treated as incorporated businesses, and representative offices are treated as sole proprietorships.
Application:
Insured parties
Generally, all employees of the aforementioned applicable businesses are covered. Part-time employees are covered where their prescribed working hours are not less than 75% of those of full-time employees*1. Employees dispatched from overseas company head offices are covered, as are presidents and representative directors of incorporated companies. However, persons dispatched from the United States, Belgium, France, the Netherlands, the Czech Republic, Switzerland, Hungary, and Luxembourg to Japan who are enrolled in medical insurance in these countries are exempt from enrolling in Japan.
Application:
Dependents
Insured parties' lineal ascendants, spouses, children, grandchildren and siblings whose livelihood is maintained mainly by the insured party are eligible to receive insurance benefits.
Application:
Nursing care insurance
This applies only to those of 40 years or over.
Benefit:
Medical expenses
70% of expenses incurred for medical treatment at designated Insurance Medical Institutions (this refers to medical institutions which have been designated as acceptable for medical insurance purposes; almost all medical institutions in Japan are designated) are covered by insurance, while the insured party must pay the remaining 30%. This also applies to dental expenses.
Benefit:
Overseas expenses
If an insured party incurs medical treatment expenses at a medical institution while staying or traveling overseas, he/she can apply to be reimbursed after returning to Japan. The amount of medical expenses incurred overseas is converted into a comparable amount of Japanese medical expenses, and 70% of that amount is reimbursed. It should be noted that this also applies to foreign nationals insured under this system who receive medical treatment in their own countries or other countries outside of Japan.
Benefit:
Excessive medical expenses
If the amount of medical expenses (e.g., the portion of medical expenses payable by the insured party) an insured party pays to a single medical institution within a single calendar month exceeds a predetermined amount, the amount of expenses excess of that predetermined level shall be reimbursed to the insured party as "Excessive medical expenses."
Contribution General insurance premiums for the Japan Health Insurance Association Run Health Insurance are 10.00% (in Tokyo*4, those of 39 years or under) of each insured party’s standard monthly remuneration*2 (maximum: 1.39 million yen) and standard bonus*3 (maximum: 5.73 million yen per year). For those of 40 years or over, 11.82%. In either case, the insured party and the employer share the premiums equally (revised in March 2023).
In the case of Union Run Health Insurance*5, a certain amount of leeway in deciding insurance premiums is granted to the managing union.
Notification Notifications must be submitted to the local Pension Office or Health Insurance Union Office within a period of five days starting on the day following that on which participation in the insurance program was established.
Ineligibility for Health Insurance (National Health Insurance)
Application People who are not eligible for Health Insurance coverage as described above must enter into the National Health Insurance scheme run by their local city, ward, town or village government.
Benefit With a few exceptions, National Health Insurance benefits are virtually the same as those under the above-described Health Insurance.
Premium Premiums are determined by each operating local government within certain limitations.
  1. (Note)

    In Japan, everybody has an obligation to take out one of the above forms of public health (medical) insurance. Because you will therefore inevitably have Health Insurance in Japan, if you choose to take out private insurance with an overseas company, it is better to ensure that the coverage of that private insurance does not overlap with your Japanese public insurance coverage.

  1. *1

    Part-time employees of an enterprise with 101 or more employees (51 or more from October 2024) who work at least 20 hours per week and receive a monthly pay of at least 88,000 yen are also insured. At an enterprise with 100 or fewer employees, part-time employees meeting the same requirements become insured based on the agreement between the employer and employees (excluding students).

Contribution:
Lump-sum Withdrawal Payments
When a foreign national who has at least 6 months of coverage periods under Employees' Pension Insurance and returns to his/her country without fulfilling entitlement period of the public pension systems, he/she can claim Lump-sum Withdrawal Payments for the amount basically corresponding to the coverage periods under Employees' Pension Insurance, 36 months at most.
Notification Notifications must be submitted to the local Pension Office within a period of five days starting on the day following that on which participation in the insurance program was established.
Ineligibility for Employees' Pension Insurance (National Pension Insurance)
Application Every person aged between 20 and 59 (inclusive) residing in Japan and without Employees’ Pension Insurance must be a part of the national pension system. Contributions are a fixed amount per month (16,980 yen from April 2024 to March 2025) and participants in the system are eligible for Old-age Pension, Disability Pension and Survivor’s Pension as well as Lump-sum Withdrawal Payments for a foreign national similar to that of the above-mentioned Employees’ Pension Insurance system.

At an enterprise with 100 or fewer employees, part-time employees meeting the same requirements become insured based on the agreement between the employer and employees (excluding students).

4.9.6 Labor and social insurance coverage of representative office

Labor insurance (Workers' Accident Compensation/Employment Insurance): In principle, when the individual, who is working at the representative office of a foreign corporation, falls under the definition of "workers" under the Labor Standards Act in Japan, he/she is eligible for Industrial Compensation Insurance. Whether the representative of the office is applicable to the definition of "workers” or not is respectively determined based on the actual situation of work. When the representative of the office is not a worker, the labor insurance does not apply. However, under certain conditions, there is a scheme in place to allow the representative insured by Worker’s Accident Compensation Insurance as a special enrollment at his/her own cost.

Social insurance (Health/Employees' Pension Insurance): In case of a representative office with less than 5 employees, in principle voluntary coverage with the representative of the office as the employer (the representative does not become the person insured) is available. If a representative office has 5 or more employees and falls under the prescribed kinds of businesses, as a general rule, insurance coverage is mandatory. In principle, a representative does not become the person insured, because a representative is an employer of sole proprietorship. However, as an exception, a representative can sometimes be granted eligibility to be insured if documents certifying the representative’s status as an employee of the overseas head office are submitted. However, the ultimate decision to allow for this exception lies with each local competent authority.
