Mount Tateshina, known as the 'Suwa Fuji' due to its symmetrical volcanic shape, reaches an elevation of 2,531 meters in the Yatsugatake mountain range. The mountain is an extinct volcano composed primarily of andesite, offering diverse climbing routes ranging from forest trails to steep, rocky scrambles. Its peak provides panoramic views extending to the Northern Alps and the Yatsugatake massif. The landscape transitions from broadleaf forests at the base to alpine flora near the summit. The Tateshina-guchi and Suzuran-toge trailheads are the primary access points for hikers. The mountain is characterized by a significant caldera-like top area and scattered volcanic boulders.
