A terminal-period megalithic chamber exposed on the south slope of a hill branching from the Ikoma Mountains at Uchiage, Neyagawa — northern Kawachi's answer to the Oni-no-Manaita & Oni-no-Setchin↗, tracing the spread of Asuka's chamber culture.
Finds & research
Hollowed-out (kurinuki-type) side-entry chamber of two granite stones; Sue-ware sherds, and gaki-bowl fragments from a medieval deposit (Neyagawa City Board of Education report).
Official status & archaeological view
Official status
National Historic Site (1973).
Archaeological view
Its mound earth gone, the exposed chamber — two granite megaliths, the lid hollowed out and set on a flat base stone (0.9m × 2.2m inside; lid ~3m across) — has an uncertain mound form: the 1973 designation note estimated a square mound about 15m per side, while Neyagawa City notes that stones found in a 1988 excavation suggest an octagonal mound. Built in the mid-7th century (Terminal Kofun period), it is the only side-entry chamber in northern Kawachi.
Field notes
Behind Uchiage Shrine; the chamber can be seen up close. Near JR Neyagawa-Koen Station.
