A group of three keyhole mounds in Anashi, Sakurai City, Nara — a National Historic Site. Built in the Late Kofun period (late 6th century); the largest, Mound No.2, is ~75m long. The three keyhole mounds are arranged in a rare linear row, and their horizontal stone chambers yielded rich grave goods including horse trappings. Mound No.1 is one of the few tombs in this area whose stone chamber interior can be entered. Located along the Yamanobe-no-michi, it can be visited together with the Keiko and Sujin imperial mausolea and the Oyamato–Yanagimoto kofun groups.
The horizontal stone chambers yielded horse trappings (bridle fittings, umbrella-shaped ornaments, cheekpieces), weapons, armor, Sue ware, and personal ornaments. Mound No.1 held an assembled stone coffin (displayed at the Museum of the Archaeological Institute of Kashihara).
About a 5-minute (≈300m) walk northeast of Makimuku Station (JR Manyo-Mahoroba Line). Adjacent to the south of the Keiko Imperial Mausoleum, along the Yamanobe-no-michi hiking route. The horizontal stone chamber of Mound No.1 is open for interior viewing. The assembled stone coffin and finds from Mound No.1 are displayed at the Museum of the Archaeological Institute of Kashihara.
