Amanagawara is a large cave where eight million gods are said to have consulted when Amaterasu Omikami hid in Amanoiwato. Since some time ago, the stones have been piled up by the hands of people praying, giving it a mystical and fantastical atmosphere.

At Tenyasu River, you can enjoy the scenery of stonework and caves. It is also said that if you make a wish by piling up rocks from Tenyasu Kawara, your wish will come true, so many people pile stones there.

For parking, please use the parking lot of Amanoiwato Shrine Nishihongu, which is located far away.
