Asahi Onsen or Hakusan Onsen in Nirasaki?
Compare Asahi’s naturally carbonated, source-flowing spring with Hakusan’s outdoor views and art. Check bus access, hours and weekly closures.
Checked: September 27, 2026
Nirasaki’s Asahi Onsen and Hakusan Onsen are both local day baths, but their appeal is not the same. Asahi is about the water: the city’s tourism page describes a sodium chloride–bicarbonate spring with fine natural carbonation and direct flow. Hakusan is more of a scenic stop, with outdoor baths, views toward the surrounding mountains and a collection of local art on display.

| From Nirasaki Station | Bus to Ozone, then about a 10-minute walk, or taxi | Municipal bus to the Omura Art Museum stop, then about a 2-minute walk, or taxi |
Asahi is the water-focused visit
The current adult rate for visitors from outside Nirasaki is ¥750; children through elementary school pay ¥500. Local resident rates are lower. Asahi is open 10 am–8 pm and normally closes Tuesdays and Fridays, with a holiday-related shift noted by the city.
Its tourism listing says the spring rises from about 1,200 metres underground and reaches the baths without added water, reheating, circulation or chlorine. Fine carbonation is a feature of the source. This description comes from the facility’s public information; it should not be turned into an unsupported claim about health effects or assumed bath temperature.
From Nirasaki Station, the city bus toward Ozone leaves you with roughly a ten-minute walk. A taxi takes about ten minutes. The bus is workable if its timetable fits your day, but this is not a bath right beside the station.
Hakusan is the better fit for a longer evening
Hakusan charges ¥700 for adults and ¥500 for children aged three through elementary school. It is open 10 am–9 pm, usually closes Wednesdays, and opens on public holidays. The monthly closure calendar can include substitute days; check its current notice before travelling. The September 2026 calendar, for example, lists September 30 as a closure.
The facility has an outdoor bath with views toward the Yatsugatake and Kayagatake area, plus an art collection associated with the Nirasaki Omura Art Museum. The view depends on weather. Its published spring data lists 44°C at the source and a sodium-chloride/bicarbonate spring; that is not a promise that every bathing pool is 44°C. Last admission is 8:15 pm.
The municipal bus to the Nirasaki Omura Art Museum stop leaves only a short walk to the entrance. A roadworks notice currently lists traffic restrictions on nearby roads from May 7 through November 24, 2026; drivers should check the posted detour map. Hakusan’s rules exclude tattooed guests and anyone wearing diapers or training pants from the baths. Asahi’s public listing does not settle the tattoo question, so contact that facility directly if you need to know.
A practical choice
Choose Asahi if the spring’s documented water characteristics matter more than a view or a late closing time. Choose Hakusan for the outdoor setting, art and an extra hour before closing. Both are easier by car or taxi than by casually turning up on a bus; check the day’s service and closure calendar before committing.
