The north of Shizuoka prefecture and the southeast of Nagano prefecture. This mountain is located at the center of the South Japan Alps. The east peak is at an elevation of 3,052 m and the west peak where second triangulation is set is at an elevation of 3,047 m. Looking from Sanpuku pass, Tengu-iwa can be seen on the left and Mt. Kitamata-dake on the right. That view is dignified and beautiful. Also the view from the summit is phenomenal. The main ridgeline descends sharply at Tengu-iwa and it runs from Mt. Gonemon-yama to Mt. Hontani-yama and Sanpuku pass. The dynamic view of the high-altitude mountain makes one’s willingness to climb. This is the mainstay of the Akaishi mountains.
Mt. Shiomi-dake: Elevation 3,052 m
It can be hiked from the Arakawa Three Mountains or from the direction of Mt. Kita-dake. Some like the long trail, however, it requires many days to complete. There are actually routes to climb only Mt. Shiomi-dake. Those are the Shiomi-shindo route, Shio-kawa route, and the Torikura route. Unfortunately, the Shiomi-shindo and Sho-kawa routes are either lost due to the damage from a Typhoon or requires a 20 km walk on a logging road. The Torikura route still exists and a trailhead is accessible by your car or bus. By using this route, this mountain can be hiked in one night and two days. Shiomi-koya Mountain hut, however, does require a reservation to stay. Make sure that you make a reservation before you enter the mountain.
