Route Guide

A-Basic  course sorted by trailheads

  1. Akaishi o'ne Route
  2. Arakawa-dake Roundabout Route

Mt. Akaishi-dake: Elevation 3,210m


This mountain is climbed often with The Arakawa Three mountains, however, a route starting from Sawara-jima to Mt. Akaishi-dake via Mt. Ko-Akaishi dake then proceeding to Mt. Hijiri-dake, is popular as well.  In that case, it is time efficient to descend from Hijiri-daira-koya Mountain hut to Hijiri-sawa trailhead and walk to Sawara-jima.  However, it requires more than three nights to complete the route.  If time is limited, a round trip from Sawara-jima to Mt. Akaishi-dake is recommended. On this route, you may stay at Sawara-jima the night before and stay another night in the mountain.  If you are aiming to climb Mt. Akaishi-dake only, then this course is recommended.  Most hikers choose this route.  Also, another route from Mt. Hijiri-dake to Mt. Akaishi-dake is introduced as the Southern Japan Alps ⑨ Mt. Hijiri-dake.  Please refer to the route if interested.
