Mount Kesamaru

Mount Kesamaru is a peak rising to about 1961 meters, straddling the boundary between Tochigi and Gunma Prefectures. The terrain consists of multiple summit points covered in thick forest vegetation.

A triangulation station was built here during the Meiji period as part of Japan's early systematic mapping efforts. This station represented the country's growing focus on precise geographical documentation during that era.

The mountain belongs to several collections of celebrated Japanese peaks, reflecting how locals categorize and value mountains across regions. Visitors notice its status through the many trekking communities that reference these official mountain lists.

Various trails lead to the summit from different starting points, with the Tōnosawa Trailhead offering one of the more direct routes requiring about 2 hours of climbing. Visitors should come prepared for typical mountain conditions including changing weather and uneven ground.

The front and back peaks are no longer connected by their original trail, as natural erosion has destroyed the passage. This creates two distinct hiking experiences on the same mountain.
