Shinzan Shrine: A Hidden Oga Power Spot Where the Namahage Legend Lives On

Shinzan Shrine in Oga City is an old shrine set on Mount Shinzan, one of the three sacred peaks of Oga. According to shrine tradition, in the age of Emperor Keiko, when Takenouchi-no-Sukune toured the northern provinces, he came down to the land of Oga, climbed Yushutsuzan, the former name of Mount Shinzan, and enshrined the two deities Ninigi-no-Mikoto and Takemikazuchi-no-Mikoto. Later it received the devotion of successive lords such as the Ando and Satake families, and in the Meiji era it was renamed Shinzan Shrine. Deeply tied to the Namahage legend of Oga, it is a center of local faith.

Enjoying the Seasons

From spring into summer the mountain trees are wrapped in green, and merely walking the path calms the heart. In autumn the surrounding foliage is beautiful, and its harmony with the old shrine makes for a graceful season. Winter is also when rites tied to the Namahage are held, and the snow-clad precincts give off an even more mysterious mood. In particular, the Namahage Sedo Festival held in the precincts in February, with the figures appearing amid snow and flame, is dreamlike.
