Suyama Kofun, Ancient burial mound in Kashiba, Japan
The Suyama Kofun features a keyhole-shaped layout with a total length of 204 meters and surrounded by deep moats filled with water.
Built between the late 4th and early 5th centuries, this burial mound received the Special Historic Site designation from the Japanese government in 1952.
The tomb contains multiple burial chambers, ritual spaces, and numerous clay figurines that demonstrate the funerary practices of ancient Japanese nobility.
Visitors can observe the entire structure from an observation platform on the southern side, with the site accessible throughout the year.
The moat system around the tomb currently functions as an agricultural reservoir, creating a distinctive island-like appearance for the burial mound.
