Overview

~90m keyhole mound in Tamura-cho, Kameyama City, Mie Prefecture. The largest in the northern Ise region (late 4th century), designated by the IHA as the mausoleum of Yamato Takeru (Nobono Tomb). The site is traditionally associated with the legendary hero's death at Nobono, as recorded in the Kojiki and Nihon Shoki. Nobono Shrine stands nearby.

Two views on the occupant

Archaeological view
A roughly 90m keyhole mound in Tamura-cho, Kameyama. An IHA survey in 2013 measured the rear at 54m across and 8.5m high; it is the largest keyhole mound in northern Ise. Kameyama City dates it to the late 4th century. Also called Chojizuka, it was designated as Yamato Takeru's tomb in 1879; that traditional attribution does not establish the archaeological identity of its occupant.
Imperial Household Agency view
Designated in 1879 by the Imperial Household Ministry (now the IHA) as the Nobono Tomb of Yamato Takeru, and now managed by the IHA; this traditional attribution is distinct from archaeological identification.

Field notes
