The Republic of Japan (ROJ; Japanese: 日本共和国, Nihon Kyōwakoku), informally known as West Japan (Japanese: 西日本, Nishinihon), is a sovereign state located in the western part of the Japanese archipelago. Located in the Pacific Ocean, it lies to the east of the Sea of Japan, People's Republic of China, Korea and the Soviet Union, stretching from the border of the People's Republic of Japan in the northeast to the East China Sea and Taiwan in the south.
The Republic of Japan was established in 1949 in areas of the Japanese Empire which were occupied by the Allied Pact after Japan's defeat in the Second World War. It is a republican democracy, in contrast to East Japan, which is a single-party communist state. Though constitutionally a republic, the throne of West Japan remains open, and the monarchy may be restored should a valid claimant be found.
West Japan maintains a very large military relative to its size, which is focused on defending the mutual border with East Japan, as well as protecting the Republic from attack by other powers in the region, particularly Korea and the People's Republic of China. The Allied Pact also maintains military forces within West Japan.
West Japan is a highly developed country, with one of the highest life expectancies in the world and very low homicide and infant mortality rates. West Japan has a gross domestic product of £1,696,211,379,825.76 and GDP per capita of £34,888.57.
West Japan is a member of the League of Nations and Allied Pact.
West Japan is divided into twenty-nine prefectures and the city of West Tokyo:
