West of the site of Motsuji's main hall, Enryuji, stands an earthen platform surrounded by cedars. Enormous foundation stones lie here, at what is believed to be the site of Kashoji, a temple hall recorded in Azuma Kagami, the official history of the Kamakura Shogunate. The site is not only almost the same size as Enryuji, but it also has the same configuration of hall and corridors as Motsuji's central hall. This suggests that Kashoji was given equal status in the temple heirarchy. Whether one believes the temple history's account that attributes Motsuji's founding to Ennin (Jikaku Daishi, third head abbot of the Tendai sect) in 850, the question of Kashoji's existence before Fujiwara no Motohira's twelfth-century construction of Enryuji persists.
