Noboribetsu’s only onsen bathhouse — two springs for ¥500
While day bathing at Noboribetsu’s hotels usually costs ¥1,000–2,000, Sagiriyu in the middle of the onsen street charges ¥500 for two 100% free-flowing waters: a strong sulfur spring drawn from Jigokudani and an alum spring that, among Noboribetsu’s nine types, can be bathed in only here. The sulfur bath is milky and pungent; the clearer alum bath has long been called the “eye bath” for its reputed benefit to eye ailments. No rotenburo, but there is a sauna and cold plunge — perfect before your bus after touring Jigokudani.
Tips & cautions
- It is a sento: no soap, shampoo or towels — bring or buy at the desk.
- Buy tickets at the machine by the front desk; the ¥710 day pass lets you rest in the tatami room and re-enter.
- The acidic sulfur water tarnishes silver and stings eyes; the alum bath is acidic too, so mind cuts.
- The alum bath has at times been suspended with only sulfur water supplied — check notices.
- Quietest just after 9:00 and in the evening.
Getting there
Donan bus ~15 min from JR Noboribetsu Station to the Noboribetsu Onsen terminal, then 2 min on foot (mid-onsen-street, Noboribetsu-Onsen-cho 60). ~10 min by car from Noboribetsu-Higashi IC; free parking for 40.
Before you go
- No official tattoo policy is published — ask at reception.
- As a communal bath there is no soap or shampoo — bring your own or buy at the shop.
- The water runs hot (43–45°C). Don't add cold water; take short repeated dips instead.
- Last entry is 30–60 minutes before closing.

A large hotel whose top-floor 'sky' open-air baths look over the Noboribetsu hills. Day use in two windows — 5–9 am and 11 am–7 pm — for ¥1,200. A little away from the main strip, so quieter.
Ōyunuma River natural foot bath
A free foot bath in an actual river of hot spring water flowing out of Ōyunuma pond, at the end of a forest boardwalk. The perfect finish to a Jigokudani walk. Daylight hours; the trail may close in deep snow.
