- Two garden baths, Japanese and Western, swapping weekly on Sundays
- An outdoor Finnish-style rolyu sauna and a rock-salt pit
The free-flowing 'hot water of heat'
Hakodate Yumoto Hananoyu is a fresh-spring public bathhouse in Kikyo-cho, Hakodate. Its chloride spring, close to seawater in composition, is called the 'hot water of heat' for its strong warming, slow-cooling quality, and its mildness suits older visitors and small children. A 2022 analysis gives 640 litres a minute at 70.5°C, pH 7.0.
Garden baths and saunas
The Japanese- and Western-style garden open-air baths swap between the sexes every Sunday, so each visit brings a different view. Outside are Finnish-style rolyu saunas (barrel, kuvel and rolyu) with heat-wave sessions, and a recreated rock-salt cave, the salt pit, which costs nothing extra and welcomes toddlers and older visitors.
Visiting for the day
Open 10:00-22:00 (last entry 21:15) with irregular closures. Bathing is 550 yen for adults, 150 yen for pupils and 80 yen for toddlers, and the sauna is 170 yen with a bath ticket. Since shampoo is not provided, buy it at the desk or bring your own; tattooed visitors are refused. A minute from the Hakodate interchange, it is easy to stop at between sightseeing.
Before you go

- As a communal bath there is no soap or shampoo — bring your own or buy at the shop.
- Payment is usually by ticket machine in cash — bring coins.

Dai-ichi Takimotokan
Hokkaido's flagship onsen ryokan: a vast 5,000 m² bathhouse overlooking Jigokudani with 35 tubs fed by five spring types — sulfur, salt, sulfate and more. Day bathing is accepted from 9:00 to 18:00. An indoor heated pool makes it good for families. Tattoos not permitted.
Yumoto Sagiri-yu
The only bathhouse-style onsen in the middle of Noboribetsu's resort strip. Two spring sources piped from Jigokudani — sulfur and the alum 'eye bath' found nowhere else — for ¥500.
Noboribetsu Sekisuitei (day use)
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.
