In the temple's vast graveyard behind the main hall, inside caves called yagura, are buried all the chief priests of the temple. Two "yagura" are dedicated to Hōjō Masako and her son Minamoto no Sanetomo, who was assassinated while still young by nephew Kugyō on the stairs of Tsurugaoka Hachiman-gū. Masako and Sanetomo's ashes are not actually there, though, because they were put in a temple, Chōshōjū-in, which no longer exists, and are therefore lost.
