This two-day onsen tour starts at TASHILOG GARAGE in Hachioji and heads west on the Chuo Expressway toward Achi Village in southern Nagano. The destination, Hirugami Onsen, is a beauty-of-the-skin hot spring in a village certified by Japan's Ministry of the Environment as having the nation's best starry skies. Quiet inns line the valley stream, and at night you can look up at a blanket of stars on a guided tour.

Course Highlights

  • Long Chuo Expressway cruise — From Hachioji IC through Suwa and the Ina Valley, riding south through a landscape framed by the Southern and Central Alps.
  • Autumn colors at Sonohara and the Heavens Sonohara foothills — A ropeway with major elevation change offers an aerial walk through the famous three-tiered autumn foliage.
  • Hirugami's silky hot spring and starry skies — Stay at a traditional inn with soft, smooth spring water and enjoy Japan's finest stargazing.
  • Shinshu soba — Fuel up on Achi's signature soba before the ride home.

Riding Tips

The route mixes mountain roads with long expressway stretches. Pack warm gear and plan your fuel stops. On autumn weekends the ropeway area gets crowded, so an early start is recommended.
