A small mound of outsized importance: its finds show Kofun-period Japan linked to the eastern end of a vast Eurasian trade network. The objects are held by the Tokyo National Museum and designated Important Cultural Properties.
Finds & research
A Roman cut-glass bowl, a Sasanian glass dish, gold plaques and spangled ornaments (Tokyo National Museum; Important Cultural Property).
Two views on the occupant
Archaeological view
A rectangular mound about 22m east–west and 15m north–south near the centre of the Niizawa Senzuka group, built in the late 5th century. An undisturbed burial found in the 1962 excavation yielded grave goods brought along the Silk Road — a Roman cut-glass bowl, a Sasanian glass dish and gold ornaments — suggesting an occupant of continental (Korean or northern Chinese) origin.
Imperial Household Agency view
Not an IHA mausoleum. One mound within the National Historic Site "Niizawa Senzuka Kofun Group" (designated 1976).
Field notes
The mound itself is small; the finds are shown at the Tokyo National Museum.
