Mabechi River

The Mabechi River (馬淵川) is a river located in northern Iwate Prefecture and eastern Aomori Prefecture, in the Tōhoku region of northern Honshū in Japan.

Overview
The Mabechi River is 142 km long and has a watershed of 2050 km2.

The Mabuchi River rises from the Sodeyama Plateau in the Kitakami Mountains of northeastern Iwate Prefecture and flows to the northeast between the Kitakami Mountains and the Ōu Mountains through eastern Aomori Prefecture into the Pacific Ocean at Hachinohe, Aomori. The Port of Hachinohe is located at the mouth of the river. The city of Hachinohe utilises water from the Mabechi River for industrial purposes.

Near the boundary between Ninohe and town of Ichinohe, the river passes through a valley with cliffs, rock formations and pools. Geologically, the surrounding hills are composed of andesite and are the remnants of an ancient submarine volcano. The ravine is flanked by a 280-meter monolithic cliff labelled the Ogami-iwa (男神岩) on one side, and the Megami-iwa (女神岩) on the other. Nearby Mount Torigoe (鳥越山) (371.1 meters) is regarded as a holy mountain, and houses a statue of Kannon Bosatsu in a cave which is an object of pilgrimage. These rock formations and the mountain have been designated a National Place of Scenic Beauty and Natural Monument since 2006. The area is located within the Oritsume Basenkyō Prefectural Natural Park.
