Located within a forest in the western suburbs of Tokyo and named for the ancient Musashi Province, the site contains the mausolea of Emperor Taishō and Emperor Shōwa, as well as those of their wives, Empress Teimei and Empress Kōjun.

The imperial graveyard in Hachiōji is designed as a semi-natural planted space which mainly consists of woodland, rocks and trees.

In addition to the stone-topped Imperial mausolea, it also contains smaller monuments and religious structures, like Torii.

The approach to the Musashi Imperial Graveyard from the Kōshū Kaidō is lined with zelkova and the mausolea planted with cryptomeria.

This adaptation of the imperial funeral rites will mark a historic change from some 350 years in which in-ground burials were the norm for monarchs and their spouses.
