At Mt. Oe, where the legends of Shuten Doji remain, you can see beautiful seas of clouds as autumn turns into winter. At the foot of Mt. Oe, due to the big temperature difference between night and day Yura river basin, it is said that fog readily forms, and the fog that builds up between the mountains looks like a sea of clouds, and so it is called the “sea of clouds.” You can see the sea of clouds in early morning from November to December. Situated at the eighth station on Mt. Oe, Onitake Inari Shrine is a famous spot for viewing the spectacular sea of clouds.
