Terminology

The term mainland Japan is used to refer to the mainland from the remote islands. It is also used when referring to the main islands Hokkaido, Honshu, Kyushu, Shikoku and Okinawa.[5] It included Karafuto Prefecture (Sakhalin) until the end of World War II.

The term Home Islands was used at the end of World War II to define the area of Japan to which its sovereignty and the constitutional rule of the Emperor would be restricted. The term is also commonly used today to distinguish the archipelago from Japan's colonies and other territories in the first half of the 20th century.[6]
