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.
