"Japan's gateway to the underworld where the living commune with the dead"
Osore-zan Boto-ji
Mutsu, Aomori Prefecture, Japan
Osorezan, the mountain of fear, rises as one of Japan's three most sacred mountains. Founded in 862 CE after a divine vision led the monk Ennin to this volcanic caldera, Bodaiji Temple stands where Japanese mythology places a gateway between worlds. Sulfurous vents, charred landscapes, and a pristine lake create an embodied experience of Buddhist hell and paradise. Itako spirit mediums still summon the dead here for grieving families.

Founded in 862 CE by the monk Ennin after divine vision, Osorezan has served as a gateway between worlds for bereaved families for over 1,100 years.
Origin Story
In 862 CE, the monk Ennin received a divine vision in a dream guiding him to this remote volcanic location on the Shimokita Peninsula. Recognizing the supernatural power of this gateway between worlds, he founded Bodaiji Temple with Jizo Bosatsu as its main image. The souls of dead children and unborn babies were understood to gather at Sai no Kawara, the riverbed along the Sanzu River, where they build piles of pebbles trying to reach paradise. Demons constantly destroy their cairns, but Jizo Bosatsu protects them.
