Daidarabotchi (ダイダラボッチ), are gigantic yokai (supernatural phantom-like creature) in Japanese folklore.
It is said that their gigantic footsteps are responsible for lakes and various bodies of water in Japan.
In one story, a daidarabotchi once weighed Mt. Fuji and Mt. Tsukuba in its hands to see which is bigger and heavier, and when it found out that Mt. Fuji is bigger, it dropped Mt. Tsukuba in the ground.
The force of the drop caused Mt. Tsukuba's peak to split, which is allegedly the origin of it's twin peaks now.
