Mori Shogunzuka Kofun is a significant keyhole-shaped burial mound located in Chikuma City, Nagano Prefecture. It is recognized as one of the largest keyhole-shaped tombs within Nagano. A unique feature is its elliptical shape in the rear circular section, shaped by the natural topography. The mound is covered with stone cladding (fukiishi), and the arrangement of Haniwa (clay figures) showcases the advanced construction techniques of that era.
This tomb is estimated to have been constructed during the early Kofun period (late s 4th to 5th century). This was an era when keyhole-shaped tombs were widely built across Japan, and the site serves as an important archaeological resource reflecting connections with the central Yamato Court. Numerous other circular tombs and small-scale burial sites belonging to the clans that inhabited this region can also be identified nearby.

The most striking feature of Mori Shogunzuka Kofun is its unique shape and structure. Because it was built upon a winding ridge, the rear circular part is nearly elliptical rather than perfectly symmetrical, demonstrating how ancient builders adapted to the terrain. The mound also features stone cladding and traces of Haniwa rows. At the adjacent Mori Shogunzuka Kofun Museum, visitors can gain a deep understanding of the tomb's structure through life-sized models and various historical exhibits.
This site is primarily intended for observing historical remains and learning through museum exhibits.
