Is a Tokasan temple of the Rinzaishu Kencho-ji Sect, ranked 5th among the 5 great Zen temples of Kamakura. Built in 1188 by Ashikaga Yoshikane, a famous samurai and a chief supporter of Minamoto Yoritomo since 1180 when Minamoto Yoritomo raised an army in Izu Province. The founding priest was Taiko Gyoyu (1163-1241), who was born in Odawara and in 1181 he became a priest and studied Shingon Tantric Buddhism at Tsurugaoka Hachimangu Temple. In 1199 he became a disciple to Eisai to study Rinzai Zen. After Eisai´s death, Gyoyu was assigned to Jufuku-ji Temple. He acted as advisor to Yoritomo and his wife Masako.
The temple was originally a Tantric Buddhist temple and it was converted to a Zen temple when Geppo Ryonen, a disciple of Rankei Doryu, the founder of Kencho-ji Temple, became head priest. The name was changed to Jomyo-ji Temple between 1257 and 1259. In 1386 the temple consisted of seven buildings and 23 pagodas but many of them were destroyed by fire.
