139m keyhole mound in Tenri City, known for its excavated painted pottery.Yielded painted pottery (special pedestal vessels depicting horses, boats, buildings, and figures), offering rare insight into early Kofun funerary rituals. The site is preserved and managed by Tenri City and is accessible to walkers.
Surveys by Tenri City Board of Education. Defining finds: painted pottery (special pedestal vessels and jar-shaped vessels) bearing incised images of horses, boats, buildings, human figures, and paired-leg ring motifs — first-class evidence of funerary ritual at the Yayoi–Kofun transition. Cylindrical and morning-glory haniwa and stone paving also confirmed. Similar painted pottery from the Makimuku site and Tatetsuki site (Okayama) indicates a broad 3rd–4th-century ritual sphere.
