Health insurance provides insured persons and their family members (dependents) with medical treatment in the event they fall sick or sustain injuries while off duty, and fixed amounts of various cash benefits in the event they give birth, or pass away.
Medical treatment and cash benefits provided in the cases stated above are referred to as "insurance benefits." See here for list of insurance benefits >> "List of insurance benefits"

Benefits in kind and benefits in cash

There are two ways to provide benefits-through the provision of medical service for the treatment of sickness and injuries and through the provision of expenses required for such treatment. Medical service provided through health insurance is referred to as "benefits in kind." Cash supplied through health insurance is known as "benefits in cash."

Statutory benefits and additional benefits

Statutory benefits are prescribed benefits under the Health Insurance Act. They are available to persons covered by Health insurance plan managed by the National Health Insurance Association (Kyokai Kenpo) as well as to persons covered by Society-managed Health Insurance.
"Additional benefits" consist of benefits of its own provided by the respective Health Insurance Societies. Health Insurance Societies provide these benefits in addition to statutory benefits.

Breakdown of benefit ratios according to age

The breakdown of benefit ratios for illness and injury is determined by age.
