Toyako Manseikaku Hotel Lakeside Terrace
洞爺湖万世閣 ホテルレイクサイドテラス
A large lakeside hotel at the centre of the Toyako onsen strip. The top-floor panoramic bath and open-air tubs take in the lake, Nakajima island and Mt Yōtei beyond — and from late April to the end of October you can watch the nightly 20:45 fireworks from the water. Day use ¥1,200 on weekdays, ¥1,500 on weekends, in two sessions: 7:00–10:00 and 13:00–21:00. The chloride water holds heat well. A paid shuttle from Sapporo Station (reservation required) makes it a handy base for Shikotsu-Tōya National Park.

A 70-year-old lakeside resort on Lake Toya
Toyako Manseikaku Hotel Lakeside Terrace is a 70-year-old resort of three wings — east, central and west — in the heart of the Toyako Onsen strip. It is famous for views of the 'long-run fireworks' launched over the lake every night from late April to late October, visible from rooms and baths alike, and in 2024 it opened 'lake sauna', a swimwear pool-and-sauna complex, evolving from onsen resort to wellness resort. Day bathing runs in two sessions, 7:00–10:00 and 13:00–21:00, and the highlight is the infinity rotenburo 'Hoshi-no-yu' on the 8th floor of the west wing.
Hoshi-no-yu's infinity bath and Tsuki-no-yu's löyly sauna
Two very different bath halls alternate between men and women daily. 'Hoshi-no-yu' on the west wing's 8th floor is an infinity rotenburo whose rim seems to merge with the lake — Nakajima island ahead, Mt Yotei on clear days, and fireworks watched from the water at night. 'Tsuki-no-yu' in the central basement boasts a hybrid löyly sauna, a 45°C onsen steam sauna and an 11°C cold plunge fed with raw lake water, no chiller. On even dates women get Hoshi-no-yu and men Tsuki-no-yu, reversed on odd dates, so time your visit if the infinity bath is the goal. The water is 100% free-flowing sodium-calcium chloride-sulphate-bicarbonate spring water.
Practical details and tips
Day bathing is 7:00–10:00 (last entry 9:00) and 13:00–21:00 (last entry 20:00); ¥1,200 on weekdays, ¥1,500 at weekends and holidays, plus ¥400 for a towel set. The baths are closed for cleaning 10:00–13:00, and you may be turned away on busy days, so check ahead. The swimwear 'lake sauna' — a 20 m pool, 90°C auto-löyly sauna and open-air terrace — is included in the day fee, making a good-value half-day wellness outing. Add the breakfast-buffet (¥3,000) or weekend lunch-set (¥2,500) package to cover meals. Note that tattoos, including stickers and body paint, bar entry.

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.
