The most beautiful cylindrical water tank in Japan

A circular water tank with a diameter of about 9 m, which was constructed in 1955 to distribute agricultural water equally to the 3 neighboring areas.
It does not use any electricity and water is spewed out by forces of nature using the principle of siphon.
The scene of the water overflowing is very cool and has become a hot spot for tourists as it has been featured on SNS and other places.
It was registered as a national tangible cultural property (building) in April 2020.
