Mainland Japan(内地, naichi) is an uncommon term to distinguish the area of Japan from Okinawa and Hokkaido and the colonies that Japan used to possess in East Asia. It is somewhat confusing as Mainland Japan is defined to consist of several major islands (Honshu, Kyushu, Shikoku) and many minor ones. The term is also sometimes used to translate Honshu, the largest island.
