There are two types of spousal visas in Japan, one for spouses of Japanese citizens and one for spouses of permanent residents of Japan, although both visas are substantially the same. Therefore, it is possible for a foreign national to receive a visa to enter Japan even if his/her spouse is only a Japanese permanent resident.
Spousal visas in Japan allow the holder to work freely in almost any profession. Therefore, upon marrying a Japanese national, many foreign nationals decide to switch their visa status to a spousal visa. The main requirement for a spousal visa is that the visa holder continue to engage in activity as a spouse.
Employers, schools or relatives, among other parties, are allowed to sponsor a visa for a foreign national to come to Japan. Each of these sponsoring relationships is different and will therefore have different requirements but the general procedure is the same.
The Ministry of Justice will accept requests for disclosure of alien registration records for foreigners living in Japan. Having a copy of these records can help foreign nationals clarify the source of their immigration problems or provide evidence in an immigration dispute. However, these records contain very private information and therefore, the Ministry of Justice takes great care to avoid disclosing them to the wrong person. The ministry does this by ensuring that only applications for disclosure by certain people will be accepted.
