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.
