Japan is an island country in East Asia. It is situated in the northwest Pacific Ocean, and is bordered on the west by the Sea of Japan, while extending from the Sea of Okhotsk in the north toward the East China Sea. Japan is a highly developed country, and a great power in global politics. Its economy is the world’s third-largest by nominal GDP and the fourth-largest by PPP. Although Japan has renounced its right to declare war, the country maintains Self-Defense Forces that rank as one of the world’s strongest militaries.
Japan’s rivers are generally short and swift-running and are supplied by small drainage basins. The most significant rivers are the Teshio and Ishikari rivers of Hokkaido; the Kitakami, Tone, Shinano, Kiso, and Tenryū rivers of Honshu; and the Chikugo River of Kyushu. The soils of Japan are customarily divided from northeast to southwest into a weak podzolic zone, a brown earth zone, and a red earth zone. There are some local variations. The northern half of the Tōhoku area of northern Honshu is included in the area of brown forest soils.
