Japan has "International Social Security Agreement
(社会保障協定, しゃかいほしょうきょうてい)" with foreign countries (See the table below)
People whose home countries have "International Social Security Agreements" with Japan are given "Elimination of Dual Coverage
". "Elimination of Dual Coverage" is an agreement that prevents people from being enrolled in two countries’ pensions at the same time, and which of pension they are to be enrolled in is decided by conditions ruled by each of agreement.
And some "Agreements" can, according to their contents, give people "Totalization of Periods of Coverage
". When "Totalization of Periods Coverage" is applied, people can totalize a period they contribute to Japan’s pension with a period they will contribute (or had contributed) to their home countries’ pensions, and vice versa (*).
(*) Please note that it doesn’t mean that Japan’s pension and other countries’ pensions will be paid at once. Totalizaion of Periods of Coverage can only allow contributors of Japan’s pension to get a qualification for receiving Japan’s old age pension, and they will receive old age pension from Japanese government if they claim it after age 65, according to their contribution to Japan’s pension system.
Contents of "Agreements" vary county by country. So please understand how "Agreement" of your home county is. But we show the list of countries that have "Agreement" with Japan and have "Totalization of Periods of Coverage" in them, as of August 2018.
