The clay burial yielded the gold-inlaid Chūhei-inscribed sword with a flower-shaped pommel, swords with house-shaped pommels, stone bracelets, and other objects. The assemblage was designated a National Treasure in 2017.

Two views on the occupant

Archaeological view
An approximately 130m keyhole mound at Ichinomoto, Tenri, built in the latter half of the Early Kofun period. A 1961 excavation uncovered a clay burial in the rear and yielded swords with house-shaped pommels and the gold-inlaid Chūhei-inscribed sword.
Imperial Household Agency view
This is not an IHA mausoleum, and no historic-site designation for the mound itself has been confirmed. The excavated assemblage held by the Tokyo National Museum is a National Treasure.

Field notes

The National Treasure assemblage is held by the Tokyo National Museum. Because displays rotate, check the museum schedule before visiting.
