쇼토쿠 태자
Honaikai took a leading part in the development of "yōkai" culture in Yōkaichi city, starting in 1999. In 2002, "Honaikai" made the map of mysterious "yōkai" places for the first time. In 2007, Honaikai made a map called the "Prince Shōtoku series" which introduced twelve shrines and temples related to Prince Shōtoku. Seven maps related to raccoon dogs, foxes, and the legend of a long-nosed goblin were created. Honaikai especially focuses on Gao, a ghost that eats mischievous children. Members of Honaikai disguise themselves as Gao on February 3 and visit children.
