A self-sourced spring in the Chichibu mountains
Hoshion-no-Yu is a day-trip-only onsen facility set in the mountains of Shimoyoshida, Chichibu. Its self-sourced water is enjoyed in indoor and open-air baths, with akasuri and relaxation services on site. Chichibu travel usually centres on a car, so the free shuttle from the main stations makes this one unusually easy to reach by public transport.
Tips for use
Open 10:00–22:00, with weekday and weekend/holiday rates differing. Because towel and lounge-wear are included, an empty-handed stop works well. Evenings, when visitors return from the sights, tend to be busy, so arriving earlier means a longer, quieter soak in the open-air bath.
Before you go
- No official tattoo policy is published — ask at reception.
- Last entry is 30–60 minutes before closing.
