If you live in Hokkaido, this is the office that handles your visa extension, change of status, permanent residence application and re-entry permit.
Go early. Queues at the big bureaus start before the counters open, and the airport branches do not handle applications at all.
Addresses, telephone numbers and counter hours come from Immigration Services Agency of Japan (出入国在留管理庁). Each entry links to that office’s own page. Checked 12 August 2026.
