A great keyhole mound of the Keitai era at Gokasho, Uji, commanding the Uji–Kizu confluence, maintained as Futagozuka Kofun Park where its mass can be felt up close. The Agency for Cultural Affairs lists it as one of the mounds of the Uji Kofun Group National Historic Site, designated in 2018.
Finds & research
Cylindrical and figural haniwa; the chamber was destroyed in the Taisho era, its 18m × 9m pit detected.
Official status & archaeological view
Official status
Part of the National Historic Site "Uji Kofun Group" (2018, with the two Futagoyama mounds).
Archaeological view
A keyhole mound 112m long (rear circle 62m across, front 87m wide), two-tiered per the Agency for Cultural Affairs designation text (three-tiered in the Nara National Research Institute's site digest), with paving, double moats, and an outer bank, built between the beginning and the early part of the 6th century — Kyoto's largest of that century. Its design has been noted to parallel that of Imashirozuka↗, the presumed tomb of Emperor Keitai, spotlighting Uji's tie to his regime. The chamber was lost in the Taisho era, but its huge burial pit (18m) is confirmed.
