Each of these stages can take months to complete so applicants should be forewarned that citizenship is not granted quickly in Japan.

A Japanese immigration control officer can temporarily detain a foreign national if he or she reasonably believes that the foreign national has committed a deportable offence such as overstaying a visa or committing a crime. However, this temporary detention is only allowed in situations that require urgent action and once the foreigner has been safely detained, the immigration officer must deliver the foreigner and any evidence relating to the offense to an immigration inspector within 48 hours from the start of the detention.
Simply marrying a Japanese citizen does not automatically grant Japanese citizenship to a foreign national. Attaining Japanese citizenship must be done though the normal naturalization process. While the naturalization process is somewhat easier for spouses of Japanese citizens, the naturalization application is quite time consuming and detailed. In addition, there may be a waiting period of several years before the spouse can apply, depending on the circumstances.
