Private Onsen in Hakone: A Day-Use Room or a Ryokan Bath?

If you would rather not share a bath with strangers, Hakone offers private day-use bathing rooms and accommodation with a bath in the guest room. Decide first whether you want a couple of hours to bathe or a whole stay built around the onsen.

The opening photograph shows a bath at Gora Kadan in 2005, not a private room at Hakone Yuryo.

A bath described as “private” is not always an in-room bath. It may be a separate shared facility used by reservation. The booking conditions matter as much as the photograph.

Hakone Yuryo: prices are per room, not per person

Hakone Yuryo has 19 private rooms. Each booking is for 120 minutes, with the following tax-inclusive room prices.

Room type Capacity Weekday / weekend & holiday
Ichi-no-maki 2 people ¥10,400 / ¥11,400
Ni-no-maki 4 people ¥12,400 / ¥13,400
San-no-maki 4 people ¥14,400 / ¥15,400

These prices include tax. For example, sharing Ichi-no-maki between two people on a weekday costs ¥5,200 each; four people sharing Ni-no-maki pay ¥3,100 each. Bath towels and small towels are included; the large communal baths cost separately. Check the booking screen for periods charged at holiday rates, such as New Year.

Online reservations open one month ahead and close at 3pm the day before. After that, contact the facility by telephone. A free shuttle from Hakone-Yumoto Station takes around three minutes and runs roughly every 10–15 minutes, making the return to the station straightforward on a day trip.

Children and tattoos: use the individual facility’s rules

Hakone Yuryo removed its tattoo-related bathing restrictions on April 1, 2025. That is this facility’s policy, not a rule shared by all Hakone ryokan and onsen.

Children who are not toilet-trained cannot use the private rooms, and a group made up only of under-18s cannot book them. The communal baths have different age conditions. A family bath does not automatically mean it accommodates babies.

This is not swimsuit bathing. A private booking lets you spend the time with your own companions, but the basics remain: wash before entering the bath and keep towels out of the water.

For an overnight stay, consider an in-room bath

A ryokan’s shared private bath is separate from your room and may have booking slots or time limits. An in-room open-air bath lets you bathe while resting in your own space. A daytime soak and a bath after dinner or the next morning call for different bookings.

For example, Hakone Suishoen’s official room guide lists open-air baths supplied by its own hot spring in all 23 rooms. This is an overnight stay with gardens and buildings to enjoy, rather than Yuryo’s day-use private-room option. Prices depend on the date, number of guests and meals.

Even rooms advertised with an open-air bath can differ: the water may not be hot-spring water, and screening or enclosures vary. Check the water source, bath size, meal arrangements and check-in time in the official room description before booking on the strength of an image.

Choose a day-use room for two quiet hours of bathing. Choose an overnight stay if you want to settle into dinner and sleep without travelling again after the bath. That distinction is a useful place to start.
