Kinreizuka Kofun

Kinreizuka Kofun is a keyhole-shaped burial mound in Kisarazu with a rounded front section and rectangular back section extending over 100 meters in length. This structure displays the classical design typical of these ancient monumental tombs from Japan's ruling era.

The burial mound dates from the Kofun period between 250 and 538 CE, a time when large tombs were built for the ruling class. This era marked a period of extensive monumental construction in ancient Japan.

The name reflects ancient burial practices of Japan's ruling families. Visitors can see how the mound's shape and placement tell us about the importance these tombs held in their society.

The site lies within a cluster of ancient burial mounds that visitors can explore across the area. Comfortable shoes are recommended since walking around the grounds and viewing different mounds involves substantial time on foot.

This burial mound is part of a larger cluster of multiple ancient monuments, showing how important this area was for the ruling elite. The grouping of several tombs in one location provides a rare chance to see where multiple leaders were buried together.
