Sairyo Kofun

Sairyo Kofun is a prehistoric burial mound shaped like a keyhole from above, stretching approximately 210 meters in length with a circular section about 115 meters across. A moat between 15 and 35 meters wide still surrounds much of the structure.

This burial mound was built between 420 and 440 AD as one of Japan's largest kofun structures. It represents a period when monumental graves reflected the power and status of the deceased.

The burial mound features haniwa terracotta figures positioned around it, marking sacred spaces and showing how communities honored their dead. These clay figurines reveal the spiritual beliefs and craftsmanship of the Kofun period.

The site is surrounded by walking paths that provide access to different viewpoints of the structure. Visitors should expect uneven ground and allow time to appreciate the full shape of the mound from various angles.

Historical records suggest this tomb may have belonged to General Kikoyumi, who died in Korea and was brought back for burial. This connection links the local site to broader regional exchanges in early Japanese history.
