Modern usage

Residents of places like Hokkaidō, Okinawa and Amami occasionally use ''naichi'' to refer to the "mainland", excluding these areas. The colloquial usage is officially "incorrect", as both areas are legally within ''naichi''. In Hokkaidō, the official term that refers to Japan except Hokkaidō is ''dōgai'' (lit. outside of Hokkaidō). With ''dōgai'' becoming common even in colloquial use, ''naichi'' ceased to be used. Residents of Okinawa also use the term ''hondo'' (lit. mainland) to refer to parts of Japan outside of Okinawa. In Japanese law, the meaning of ''hondo'' is used to make a distinction between the "main islands" of Hokkaidō, Honshū, Shikoku, and Kyūshū and "outlying islands" referred to as ''ritō''. The term "main islands" (本島 ''hontō'') is used for
