History and founding 
Jakuen left Eihei-ji in 1261. He meditated in solitary with the wild animals at the base of Mount Ginnanpo, about 25 kilometres (16 mi) away. By one account, a leader of the Fujiwara clan in charge of the Ono District, Ijira Tomotoshi happened to find him during a hunt, and offered his financial support. In 1278, Tomotoshi's son Tomanari built a temple for Jakuen who apparently wished to revere Ju-ching by taking the name from the Hōkyō era in China, a period during which Ju-ching was Dogen's teacher.
