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.
Unlike student visas or work visas, the spousal visa has no restrictions on what activities the visa holder can engage in while in Japan. This means that the visa holder may work freely or participate in income generating activities that would otherwise be barred by a work or student visa.
