Koseyama Kofun Cluster

Koseyama Kofun Cluster contains multiple burial mounds with keyhole, circular, and square shapes arranged across elevated plateaus and hillsides. The mounds occupy different height levels, creating a dispersed archaeological site that spreads across the natural landscape.

These burial mounds date from the late 4th to mid-6th century, a period when ruling families grew more powerful in Japan. They mark an era of intensive construction and social development in ancient times.

The mound shapes show different burial practices that reflect how communities ranked their dead. Walking around the site, you can see how these designs communicated social status to those who saw them.

The site became part of the UNESCO World Heritage site Mozu-Furuichi Kofun Group in 2019 and is accessible via local public transportation. Plan several hours to walk between the different mounds scattered across the terrain.

Excavations at non-imperial tombs have revealed weapons, tools, and ceremonial objects from this period. These discoveries show in detail how people lived and practiced their beliefs.
