最勝寺
Saishouji is a Buddhist temple in Yamakita, Kanagawa, whose grounds include the ribbon-like Shasui Falls. The temple is home to a taiko school, and hosts a drumming contest on the fourth Sunday of each July to celebrate the falls.
The temple is fronted with rows of hundreds of jizo which are decorated with pinwheels. (Unfortunately I haven’t been able to find any explanation for this colorful phenomenon.)
