Oyamakui no Mikoto is a Shinto deity associated with Mount Hiei and Mount Matsuo, traditionally regarded as a kami of mountains and the lands surrounding them. This deity is enshrined at Hiyoshi Taisha in Shiga Prefecture and at Matsunoo Taisha in Kyoto, where devotion has long linked the kami to the guardianship of the surrounding area and its communities. Many worshippers have sought this deity's protective influence, though such benefits are matters of traditional belief rather than verified fact.
