What a Medical(Health)Insurance

It is a social insurance system aimed at stabilizing living by paying necessary medical benefits and allowances when workers and their families get sick or injured, give birth, die, etc.


In general, those who work more than 30 hours a weekare eligible for health insurance. From October, 2008, the rule was expanded to companies that have 501 employees or more and who work 20 hours or more per week.

(Even for people who do part-time jobs, it is necessary to subscribe if working hours of one day or one week and prescribed number of working days per month are 3/4 or more of regular workers).

Insurance Premium Burden

The amount that the person pays at a hospital when he/she gets sick (counter burden)

If you bring your health insurance card to the hospital, you will only need to pay 30% of the treatment fee.

How to calculate health insurance premiums

◆The standard remuneration (monthly) is determined by the rank (grade) of the amount of monthly remuneration.
