Official status & archaeological view
Official status
National Historic Site "Midoro Kofun" (1961; two mounds).
Archaeological view
Two round mounds at the mouth of the Kose valley. The south mound (about 25m across with a ~15m chamber according to Gose City; the Agency for Cultural Affairs' designation note gives a base diameter of about 15m, with a ~4.6m burial chamber and ~6.2m passage) holds two house-shaped sarcophagi, one in the chamber and one in the passage, the passage coffin's boss carved with a lotus — a famed union of kofun and Buddhist culture. The north "Tsukaana" mound (~20m; 13.4m chamber) sits in a private garden. Gose City's 2012 heritage column dates the north mound to the late to end of the 6th century and the south mound to the beginning of the 7th century (the city's tourism page gives the mid-6th century and the late 6th century); the Agency for Cultural Affairs' designation note assigns both to the Asuka period.
Field notes
The north mound lies within a private residence (Gose City).
