What is health insurance society?
A health insurance society is a public corporation that provides health insurance services in place of the government. Around 1700 health insurance societies currently operate nationwide. There are many unique benefits that result from health insurance operation by a health insurance society


Health insurance comes in several varieties

Under a health insurance system, an employer (company) and its employees pay insurance premiums to provide protection against the possibility of sudden unexpected costs following events such as illness, injury, hospitalization, or death. In this spirit of communal support, health insurance also provides compensation for living expenses in the event of illness or injury, as well as everyday activities to improve one's health. Health insurance systems generally fall into one of four general types, reflecting differences in workplaces and other factors. (See the table below.) Although the type of insurance system you join is determined by your company (workplace), all Japanese citizens are required to have health insurance.

As its name suggests, the Sony Health Insurance Society (Sony Health Insurance hereinafter) is a health insurance society insurer. It was established May 1, 1958, with the authorization of the Minister of Health and Welfare.


A health insurance society operates on democratic principles.

The health insurance society operates democratically, managed by a board whose members and directors are elected (to 3-year terms) by the employer (company) and the insured persons (employees).


A health insurance society makes the following possible:

1. Independent operations that reflect the specific conditions of society members
A health insurance society makes it easy to assess group demographic profiles and trends affecting members, such as age, gender, health conditions, and medical costs, in turn making it possible to initiate programs that best meet the needs of its members. In addition, the insured are represented by elected committee members, whose opinions are reflected in society management, creating a democratic system of management.

2. Enables payment of additional benefits
In addition to legally required insurance benefits (statutory benefits), additional benefits can be paid in accordance with the financial circumstances of the health insurance society.

3. Allows development of independent health promotion operations
Health activities can incorporate various types of health promotion operations, including preventive efforts based on various types of examinations, stamina-building activities, recreation facility operations, and health maintenance activities for the elderly.

4. Provides latitude in setting insurance premiums based on specific financial circumstances
The insurance premium rates (used to determine health insurance premiums) used by the health insurance society can be set to values in the range from 0.3% to 0.95%, depending on the society's financial circumstances and area of business. This makes it possible to set the most appropriate premium levels.
