Social Security Agreements

Japan has social security agreements with multiple countries. There are two main functions of such agreements:

1. Elimination of dual coverage (prevention of mandatory contributions to two systems)
2. Totalisation of periods of coverage (allowing periods of coverage in one country to count towards benefits in the other country)

As of 2022, all such agreements signed by Japan allow for elimination of dual coverage, but not all have provision for totalisation.

United Kingdom

The Agreement between the UK and Japan on Social Security is not a totalisation agreement. It prevents mandatory contributions to two systems. For eligible Japan-resident individuals, voluntary contributions to the UK system are possible. See United Kingdom#UK State Pension.
