The only major requirement for keeping a spousal visa in Japan is to continue to stay married to a Japanese national. In general, spousal visas do not apply to couples who divorce or where one spouse has died, although it may be possible to switch to a long term visa in some cases. It is important to note that, even if the couple is legally married, they must also meet a certain standard of marital behavior and marriages that seem fraudulent risk the possibility of having a renewal visa rejected.
