Japan – National Pension Insurance: Revised Upper Limit on Salary Base

Japan–Nat'l Pension Ins: Revision of the Upper Limit

Under new legislation passed in Japan, as of September 1, 2020, the upper limit of the monthly standard salary for employee’s pension insurance has changed. Employees will begin feeling the effects of the change in the October payroll.




The Japanese government passed legislation revising the terms of the Employees’ Pension Insurance Law with respect to setting the standard classification of the monthly remuneration to which the national pension charge applies.  The new law, and the change in the upper limit of the monthly standard salary, came into effect as of September 1, 2020.1


Though more employees will see a greater portion of their monthly salary subject to pension insurance, the changes will help ensure the financial stability of the pension insurance regime.  Employers and payroll administrators should waste no time in making the necessary adjustments so that they are in compliance with this change in the rules.  Employees will begin feeling the effects of the change in the October payroll.


Pension insurance is one of the three components of the social insurance program in Japan. Any individual who meets the prescribed conditions is expected to participate in the system as an insured person regardless of his or her nationality, unless there is a totalization agreement between Japan and the expatriate’s home country.


It is important to note that not all totalization agreements cover all three components of Japan’s social insurance program.  Accordingly, employers should review the agreements closely to understand which components are covered.

Revision of the Upper Limit

As of September 1, 2020, the upper limit of the monthly standard salary for employee’s pension insurance has changed from 31st grade/JPY 620,000 (approximately USD 5,8002) to 32nd grade/JPY 650,000 (approximately USD 6,165).
