Mount Osore (恐山)
Mount Osore is a small volcano in the middle of the Shimokita Peninsula, just west of Mutsu City. It is home to a Buddhist temple named Bodai-Ji, whose patron deity is Jizo, as well as a small lake: Lake Usori. Flowing into the lake is a small brook, which in Japanese mythology is analogous with the Sanzu River, which spirits must cross after death.
Osore-zan—the Japanese name of the peak—means “Mount Fear.” The mountain, with its barren landscapes of crushed rock and sickly-colored sulfur pools and fumaroles, is believed to be the entrance to Hell. Intermittent volcanic activity and earthquakes add to the dreadful atmosphere around the mountain that looms over Mutsu.
