OVERVIEW
What is the Spouse of Japanese National visa?
This status of residence covers the spouse of a Japanese national, a person born as the biological child of a Japanese national, and a special adopted child of a Japanese national — commonly known as the marriage visa. Unlike work-based visas, there is no restriction on the type of job you can do, which is a major advantage. At the same time, examination has grown stricter year by year in order to prevent abuse of the status through sham marriages.
Simply registering the marriage at a municipal office is not enough. Under a Japanese Supreme Court ruling (17 October 2002), a marriage is, in substance, "a relationship in which the two parties genuinely intend to build a shared life aimed at a lasting spiritual and physical union." In other words, the "substance of the marriage" is an essential precondition — if the marriage has lost its substantive basis and exists only in form, the status of residence itself will not be recognized.
