Yatsugatake-Chūshin Kōgen Quasi-National Park is a quasi-national park on Honshū in Japan. It is rated a protected landscape according to the IUCN. The park includes the Yatsugatake Mountains and the surrounding lava plateaus: Tateshina plateau, Kirigamine, and Utsukushigahara. It straddles the border between Nagano and Yamanashi prefectures. Mount Aka is the highest point in the park at 2,899 m (9,511 ft). The volcanoes of the Yatsugatake mountains erupted from the middle of the Fossa Magna and spread skirts of lava south, east and west. Lake Matsubara, Shirakoma Pond, and Lake Shirakaba attract tourists to the region for boating, skating, and camping. Utsukushigahara is a lava plateau at the northern end of the park and offers views of the Northern Alps. The extensive lava plateau of Kirigahara is popular for hiking. There are also a number of onsens in addition to the hotsprings at Tateshina. The park was designated a quasi-national in 1964.
Insider tip — At 1,400 metres on the Kirigamine plateau, this onsen sits above the cloud line for much of the year, lending bathers a sensation of soaking inside a cloud. The bicarbonate-calcium water is notably smooth, leaving skin visibly polished after a single soak. Wildflower meadows bloom around the plateau from late June through August, turning the highland gold in September. The nearest convenience store is 40 minutes away, so plan provisions and embrace the highland solitude.
