Iwate-ken (Iwate prefecture) is in the northeastern Tohoku region of the main Japanese island Honshu. Iwate faces the Pacific Ocean to the east, and is bordered by Aomori Prefecture on the north, Akita Prefecture on the west, and Miyagi Prefecture on the south. The prefecture has mountains in the west, north and east, with the valley of the Kitakami River running from north to south through the center of the province and including the capital. The coast is very rugged, with little in between the mountains and the sea.
