・Points to note
Since the scope of "family" refers to "spouse and children",Siblings and parents are not included.In addition, the family visa is not a visa that is permitted for the purpose of working in Japan or living alone in Japan because it is a visa for living in Japan with family. You should be careful.
In some cases, the spouse (wife or husband) of a foreigner residing on a student visa and their children may also be permitted to stay as dependents.
・The principle is that you are not eligible to work.
As mentioned above, working is not permitted in principle because of the visa to send family life in Japan.
However, foreigners staying in Japan on a family visa can also work part-time for up to 28 hours a week by separately obtaining permission to engage in activity other than that permitted under the status of residence previously granted.
