Suribachiyama Kofun, Ancient burial mound in Ueno Imperial Grant Park, Japan
Suribachiyama Kofun is a keyhole-shaped burial mound located in a public park. The structure features a circular rear section connected to a rectangular front section, surrounded by shallow ditches that outline its distinct form.
This mound was built in the late 5th century during the Kofun period, when such structures served as burial sites for Japanese elite. The keyhole design of the mound belongs to a widespread architectural tradition of that era.
The mound reflects how ancient Japanese honored their elite through architectural form. The keyhole shape was a widespread building method used across the region for important individuals.
The mound sits within a large park filled with other attractions and is freely accessible. You can walk around the site while exploring nearby museums, temples, and gardens at your own pace.
The mound has never been formally excavated, leaving its contents and true purpose shrouded in mystery. This unexcavated state makes it one of the few ancient burial sites where the original mystery remains fully intact.
