Spouses who are worried that their partner might file a fraudulent divorce registration in Japan can file a Non-Acceptance of Notification of Divorce (rikon fujuri moshidesho 離婚不受理申出書) in order to prevent acceptance of a divorce form. While this non-acceptance used to only last for 6 months, in 2008 the law was changed to allow such non-acceptance to be valid until withdrawn by the submitting spouse.
While trials in Japan normally take place as close as possible to the location of witnesses and evidence, sometimes witnesses from far away locations must be consulted on some aspect of the trial. However, having these witnesses come to the court from a faraway location is not always possible. Therefore, in order to facilitate the appearance of witnesses from remote areas, Japanese courts sometimes allow for the examination of witnesses by video conference.
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.
