The cave where Amaterasu hid. The spring water is selected as one of the best 100 waters, the Oshima cherry tree is designated as a natural monument by the city, and the "early rice-cake pounding" during the cherry blossom season is a traditional performance of this area.

Legend has it that Amaterasu hid there because she lamented the violent actions of Susano. It is located on the border of Shima City and Ise City. The small water source has been selected as one of the "100 best waters in Japan". (You can take the water home with you, but be sure to boil it before drinking.)
The Oshima cherry tree, designated as a natural monument by the city, is also famous. During the cherry blossom season, there is an "Association for Enjoying Cherry Blossoms, Rice Cakes and Great Water" and the "Haya Mochitsuki" Preservation Society, a traditional performing art of the Erihara area, offers rice cakes to visitors.
