Japan is an Island Nation in East Asia.
The Empire of Japan consists of five main islands: Honshu, Kyushu, Shikoku, Hokkaido, and Karafuto. Temperature can vary between subtropical and temperate. Japan is an island nation and has no land borders. Its only territorial claim postwar, to the Dokdo islands, had been abandoned by 1995 by an agreement with Korea.
Japan is a constitutional monarchy. A single dynasty had been ruling in Japan since its inception; unofficially it was called the Yamato dynasty. The present Emperor, Akihito, is the 124th descendant of Jimmu Tenno, the first emperor of Japan. He succeeded his father Hirohito at his father's death in 1989.
