Shirakami-Sanchi (白神山地, lit. white god mountain area) is a UNESCO World Heritage Site in northern Honshu, Japan. This mountainous, unspoiled expanse of virgin forest straddles both Akita and Aomori Prefectures. Of the entire 1,300 km², a tract covering 169.7 km² was included in the list of World Heritage Sites in 1993. Siebold's beech trees make up a large portion of the forest.
