Japanese social insurance system
All regular employees of workspace in Japan regardless of nationality
are required to participate in the Employees' Health Insurance System
and the Employees' Pension Insurance System, provided the number
of hours and the number of days they work at the workspaces are
generally at least three-fourths those of other ordinary employees
of those workplaces.
As proof of coverage, the insured person receives a Health insurance
Certificate for the Employees' Health Insurance System and
a Pension Handbook for the Employees' Pension Insurance System.
Employees must join the insurance Systems when they begin working
at their workplaces. Monthly insurance charges are determined according
to the insured person's salary, and are shared equally between the
employer and the insured person.
