Daidarabotchi was a gigantic yōkai in Japanese mythology, sometimes said to pose as a mountain range when sleeping. His size was so great that his footprints were said to have created innumerable lakes and ponds. In one legend, Daidarabotchi wanted to see which was heavier: Mount Fuji or Mount Tsukuba - and he weighed them on a great scale. However, when he was finished he dropped Mount Tsukuba, splitting its peak.
