Kyoshuzuka Tumulus

The Kyoshuzuka Tumulus in Oita is a sixth- or seventh-century burial chamber whose earthen mound has long since eroded, leaving only its stone walls. Four large slabs, each roughly two meters tall, form a rectangular chamber on a ridge overlooking what was likely the territory of the buried clan chief. The name translates roughly as the burial mound of rebel heads, tied to a legend about remains from a Yamato court campaign in the 720s, though the mound predates that event. The chamber sits beside the old road to Usa Jingu Shrine and is freely accessible. It is designated a Historic Site by Oita Prefecture.
