Located south of Lake Towada and bridges the central areas of Akita prefecture and Iwate prefecture. It is an area of ancient volcanic activity, and the entire plateau is dotted with boiling mud pools, steam and smoke vents and hot springs.
Mount Hachimantai is the highest peak of a group of stratovolcanos distributed around the Hachimantai plateau in the Ōu Mountains in northern Honshū, Japan. This volcanic plateau is part of the Nasu Volcanic Zone and straddles the border between the Iwate Prefecture and Akita Prefecture. The volcano is listed as one of the 100 Famous Japanese Mountains, and forms part of the Towada-Hachimantai National Park.

Lake Towada, or Towada-ko, is Honshu's largest volcanic caldera lake and also the country's third deepest lake. The area nearby is dotted with dense forests and waterfalls, and is the top tourist draw in all Tohoku.
奥入瀬川
The upper reaches, known as literally as the Oirase Stream (奥入瀬渓流 Oirase-keiryu) or as the Oirase Gorge, are famously scenic, featuring constant-flowing water since this is the drain of Lake Towada, and numerous waterfalls.
