Mausoleum of Tokugawa Shōguns Six of the 15 Tokugawa shōguns are buried at Zōjō-ji. The Taitoku-in Mausoleum of Hidetada (and the monument to his wife Sūgen'in), Ienobu, and Ietsugu had been designated National Treasures of Japan, but were burned in World War II. At present, parts of two of their graves have the distinction of being Important Cultural Properties of Japan. Additional graves are located in the cemetery behind the Great Hall. Parts of the former grounds of the temple are now occupied by a park and two hotels. Tokugawa Iemochi also Iemochi's wife, Kazu-no-Miya Chikako also buried in Zozo-ji. Sentai Kosodate Jizō (Unborn Children Garden) In one particular garden at the cemetery, rows of stone statues of children represent unborn children, including miscarried, aborted, and stillborn children. Parents can choose a statue in the garden and decorate it with small clothing and toys. Usually the statues are accompanied by a small gift for Jizō, the guardian of unborn children, to ensure that they are brought to the afterlife. Occasionally stones are piled by the statue; this is meant to ease the journey to the afterlife.
