Akakura mountain is the name given to the north-east face of Mt. Iwaki, a quiescent volcanic cone that dominates the southern Tsgaru plain of Aomori Prefecture.  The better known Iwaki mountain has three peak; Iwaki san shrine is located at its base, below a relatively smooth slope. Akakura mountain, in turn, also has three peaks, but is noted for its rough, volcanic surface and is dominated by a great gorge. For centuries, worshippers have undertaken ascetic discipline (shugyo) on its slopes, many climbing to the Waterfall of Fudo (Fudo taki) about halway up the mountain.

There are several geographical sites known as "Akakura" (lit. red storage hall) in northern Tohoku, some of which have long-term ritual and cosmological links to Mount Akakura. These include Akakura gorge on Mt. Hakkoda and the Akakura route on Mount Mahiru in Akita Prefecture.
