湯の箱 こみち
A 24-hour bathhouse in Hakodate with natural onsen water
Closed on the first Tuesday of each month, though some months run without a break, so it's worth checking ahead. Bathing pauses briefly for cleaning, from 3:00 to 4:00 and 9:00 to 10:45 on weekdays (9:00 to 9:45 on weekends), and the open-air bath and jacuzzi close from midnight to 4:00.
Daytime admission is shown above; entering after midnight costs more, 1,000 yen for the late-night rate (0:00-4:00) or 2,000 yen for the overnight block through 9:00. A 12-hour capsule-bed stay is 4,500 yen and includes loungewear, a towel set, admission and the late-night fee, with extensions at 600 yen per hour. Prices rise during peak seasons such as Obon and Golden Week.

Yunohako Komichi is a large, 24-hour bathhouse in Hakodate, reopened in 2020 under this name after a rebrand of the former Yutori health center. The baths run on natural hot-spring water kept flowing fresh, with several indoor tubs at different temperatures, an open-air bath and jacuzzi, and a cold plunge to cool off between rounds. Beyond the baths there's a restaurant, a tatami rest area, and capsule beds upstairs for guests staying longer.
