The Yakeishi Mountain Range occupies the northern corner of Kurikoma Quasi-National Park and has 13 mountains over 1,000m. Mt. Yaishishi, at an altitude of 1,548m, is the leader of this mountain range. It has the most remaining snow in the prefecture, and wetlands and ponds have developed everywhere. It is said that more than 300 species of alpine plants grow here, and the vegetation is diverse. Climbing courses include the Nakanuma course and the Tsubunuma course, as well as a traverse course that starts at Natsuyu Onsen and goes via Mt. Kyozuka to Mt. Yaishi.
