Achi阿智村

Visit Achi for a night of stargazing or onsen; a day‑trip works if you only want the mountain views.

Achi is a tiny Nagano village famous for low‑light stargazing and hot‑spring resorts. It is reachable by a 40‑minute bus from Iida Station, so a single night covers the main attractions; a day‑trip is possible if you only aim for the mountain viewpoint.

Rules in force · 5
  • East Asia ↗Every border in East Asia is a full international border, Hong Kong and Macau included: an entry permission for one never covers the next.
  • East Asia ↗Ferries between Korea, Japan and China cancel in rough seas and typhoons; keep a flight or a spare day behind every sea leg.
  • Japan ↗IC cards (ICOCA/Suica) are topped up with cash at station machines.
  • Japan ↗Smoking while walking is banned in most city centres; use designated areas.
  • Japan ↗Shinkansen bags 160–250 cm (L+W+H) need a seat reserved with the oversized-baggage area.

Entry rules depend on your passport. Full visa guide

Watch out

Safety

Achi is generally safe; main risks are sudden mountain weather changes and limited English signage, so carry a map and warm clothing.
  • English information is scarce; rely on the Japan Travel Agency page or machine‑translated village site.
  • Stargazing tours run only in summer evenings; bring warm clothing.
