Motonosumi Inari Shrine

This shrine houses the sacred spirits that were split about 60 years ago from Taikodani Inari Shrine in neighboring Shimane Prefecture. It is said the shrine originated from a story where a God posing as a white fox appeared in the dream of a local fisherman, telling him to enshrine it in the area. The most impressive part of the shrine is the 123 shrine gates that stand in a row stretching over 100m (328ft.)
