Daidarabotchi(ダイダラボッチ?, lit. "Giant") was a gigantic yōkai in Japanese mythology. 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. So he weighed them on a great scale. However, when he was finished he dropped the latter, splitting its peak. The Hitachi no Kuni Fudoki, a recording of the imperial customs in the Hitachi Province compiled in the 8th Century, also told of such a giant living on a hill west of a post office of Hiratsu Ogushi who fed on giant clams from the beach, piling the shells on top of a hill.
