Outline of Japan Health Care Insurance System

Japan's health care insurance system is facing a significant impact brought by changes of the social environment, mainly caused by the aging population, economic slowdown, advances in medical technology, and improved national awareness, thus the hidden crisis of Japan's highly developed health care insurance system is being exposed.

According to the Ministry of Health, Labor and Welfare's research, in 2025, 15.6% of the population aged 75 or older will account for 56% of the medical expenses of all Japanese citizens, without reform, this huge amount of money will bring unimaginable financial pressure to the entire medical sector and even society, the health insurance reform for the elderly group is urgent.

The Ministry of Health, Labour and Welfare proposes that, in the current adverse social environment, it is necessary to maintain a national healthcare system that not only continues to provide efficient, safe, and high-quality medical services from the patient's perspective, but also enhances healthcare and medical services with an extension of the healthy lifespan, and constructs a stable medical insurance system that is trusted by the public and is sustainable.

Therefore, the reform of the existing health insurance system in Japan focuses on the reconstruction of health insurance financing for the elderly, and a series of initial reforms have been carried out to provide more appropriate and efficient services to the elderly, as well as to equitably share the cost of medical care, which have already yielded good results.

In this passage, Kaizen will base on information from the Ministry of Health, Labour and Welfare and related regulations, briefly introduce Japan’s health care insurance system, for a reference to Kaizen’s existing and potential clients. Kaizen do provide services on enrolment of Japan insurance and calculation of payroll for Japan companies, please contact our consultants for further information.

  1. Classification of Health Insurance

    Medical insurance in Japan is roughly categorized into “public health insurance,” which is mandatory, and “private health insurance,” which is voluntary.

    (1)
    Public Health Insurance.

    Japan's public health insurance is based on the nationwide universal health insurance system (in Japanese “国民皆保険制度”), which requires that all citizens participate in and pay for public health insurance in order to reduce the burden on each other. By doing so, all Japanese citizens can enjoy a high level of medical services at a low price

    Japan's public health insurance does not impose restrictions on its usage, therefore, patients in Japan can choose the appropriate medical institutions and doctors for treatment according to their needs. This system of free choice of medical institutions and doctors is called “free access” (in Japanese “フリーアクセス”) and is one of the most significant features of the Japanese public health insurance system.

    Public health insurance is categorized into following categories (including but not limited to) based on the participants' works nature, age, and so on:

    i. National Health Insurance (NHI) (in Japanese, “国民健康保険”), is a program mainly for self-employed individuals, retirees, non-regular workers, and the unemployed.
    ii. Health Insurance Administered by Japan Health Insurance Association, which is mainly enrolled by employees of small and medium-sized enterprises.
    iii. Health Insurance Administered by Societies, which is mainly enrolled by employees of large enterprises.
    iv. Mutual Aid Association, which is mainly enrolled by Civil servants, staff of certain independent administrative corporations, staff of the Japan Post Group, etc.
    v. Medical Care System for Elderly in the Latter Stage of Life, which is for elderly aged 75 or above.

    (2)
    Private Health Insurance

    Private health insurance in Japan exists as a subsidiary of public health insurance to cover the individual's contribution to medical or miscellaneous expenses such as inpatient beds, transportation, etc., as well as to compensate for the reduction in income due to sick leaves, etc.

    Unlike public health insurance, which generally does not provide cash subsidies, most private health insurance policies provide “visiting fees” to participants based on their diagnosis, degree of injury, type of surgery, frequency of consultation, or number of days of hospitalization, etc. In addition, when certain conditions are met, the private health insurance premiums paid by the participants can be deducted from their taxable income for tax reduction purposes.

    Japan's private health insurance industry was controlled by U.S. capital in the early years. In 2021, after negotiating with rh U.S., Japan's private insurance sector achieved to go into free-market in. As the private health insurance industry has been developed for a relatively short period of time, it has been experiencing problems, such as bad incentives from the insurers or defaults on payment of insurance premiums.

  2. Health Care System

    According to official data from the Ministry of Health, Labor and Welfare, as of March 2020, the number of insurers for national health insurance is 1,716, with about 26.6 million participants; the number of insurers for association health insurance is 1, with about 40.44 million participants; and the number of insurers for societies health insurance is 1,388, with about 28.84 million participants; The number of insurers for the mutual health insurance is 85, with about 8.54 million participants; and the number of insurers for the elderly in the latter stage of life is 47, with about 18.03 million participants.

    In addition, according to a survey conducted by the Ministry of Health, Labor and Welfare, there are a total of 8,199 hospitals, 104,538 clinics, 68,028 dental clinics, and 60,171 pharmacies in Japan, including 327,210 doctors, 104,908 dentists, 311,289 pharmacists, 1,272,024 nurses, 64,819 health care practitioners, and 40,632 midwives.

  3. Procedure of Consultation with an Insurance

    When participants visit a doctor with public health insurance, coverage is usually paid through the following process:

    (1)
    The participant pays the health insurance premiums to the health insurer on a regular basis.
    (2)
    The insured person visits an insured medical institution, such as a hospital or clinic, to receive medical treatment and pays to the medical institution the portion of the rate of the medical expenses he/she should bear.
    (3)
    The insured provider submits a claim for reimbursement of the cost of the visit to the medical fees review committee (i.e., National Health Insurance Medical Fees Review Committee) and provides a bill for the visit.
    (4)
    The medical fees review committee will review the medical bill and provide it to the health insurer.
    (5)
    Health insurers pay billing amounts to the medical fees review committee.
    (6)
    The medical fees review committee reimburses the medical treatment and pays it to the insured provider.
