Nomoto Shōgunzuka Kofun

Nomoto Shōgunzuka Kofun is a keyhole-shaped burial mound situated on a mountain ridge near Chikuma. The structure extends over 100 meters in length and rises to approximately 490 meters above sea level.

The burial mound dates to the 4th century and contains a double-chambered stone structure representing one of the largest examples in eastern Japan. This construction reflects the advanced building techniques of its era.

The site served as a focal point linking regional rulers to the imperial court, as evidenced by objects discovered during excavation. These finds reflect the importance of this burial in early Japanese society.

Access to the mound requires climbing approximately 120 meters from the parking area using several possible routes. Visitors can choose between a shuttle bus road and forest stairways depending on their preference and fitness level.

The monument underwent major restoration between 1981 and 1992, during which the entire exterior stonework was rebuilt from scratch. Original decorative pottery was replaced with replicas to protect the historical integrity of the site.
