Daidara-bocchi (ダイダラボッチ) is a giant in Japanese mythology.
Daidara-bocchi is sometime described as a huge man with one eye and one leg with a straw sandal.
Daidara-bocchi was so enormous that his footprints are said to have created innumerable lakes, and ponds, and his strength is to blame for the current placement of many mountains and rivers. According to one legend, Daidara-bocchi once compared the weights of Mount Fuji and Mount Tsukuba on his scales, and when the latter fell down, its peak split in two.
The Waraji Matsuri (Festival of Huge Straw Sandal) is a festival that takes place in September every year in Nakiri, Daio-cho, Shima-City. People throw a huge waraji (a straw sandal 3m X 1.2m) into the ocean and pray for peace as well as a rich fish harvest.
