Kusatsu Onsen Guide: Day Baths, Prices and Access

JGO! editorial team — WEBMARKS Inc. (Fujisawa, Kanagawa)

Kusatsu Onsen has several day-use bathing facilities, but they differ in price, bathing features and seasonal hours. The main choices covered here are Otakinoyu, Gozanoyu and the Sainokawara open-air bath. Their published adult admission prices range from ¥800 to ¥1,200, and the facilities do not offer the same extras or bathing arrangements.

The information below is based on facility and transport details checked on 4 November 2026. It is not a guarantee that a bath, parking area or bus service will be available as described on your travel date. Before setting out, check the official facility notice and the current bus timetable for your intended day.

Choose a day bath and compare the listed prices

The three facilities charge separately, so there is no single town-wide day-bath ticket in the information presented here. The table compares published adult and child admission, hours, last entry and the main feature that distinguishes each place. Seasonal opening hours matter particularly at Gozanoyu and Sainokawara, where the morning opening time changes in winter.

These are facility figures recorded on 4 November 2026, not hotel-room rates or confirmation that any facility will be open on a particular day. Check current notices for temporary closures and other changes, and confirm the applicable child category with the operator. If a specific bathing feature, private arrangement or access requirement is important to your visit, contact that facility before travelling.

For a simple price comparison, Sainokawara has the lowest listed adult admission at ¥800, followed by Gozanoyu at ¥900 and Otakinoyu at ¥1,200. The lower price does not mean the facilities provide the same experience: Sainokawara is an open-air bath, Gozanoyu offers indoor baths, and Otakinoyu lists several bathing features including a sauna and awase-yu. Optional services, such as Otakinoyu’s private bath or Gozanoyu’s yukata-walk option, have separate terms and should not be treated as included in standard admission.

Otakinoyu: bathing features, private baths and practical details

Otakinoyu is a day-use facility at 596-13 Kusatsu, Kusatsu-machi; it is not accommodation, so a visit there does not provide an overnight stay. Its official guide lists adult admission at ¥1,200 and child admission at ¥600, with opening hours of 09:00–21:00 and last entry at 20:00. The facility’s FAQ describes a large bath, an open-air bath, awase-yu, a cold bath and a sauna.

Awase-yu is a sequence of baths at different temperatures, which visitors move through in turn according to the facility’s explanation. The FAQ also says that Otakinoyu introduces cloudy-white water on the second and fourth Saturdays. Treat that as a facility notice rather than a promise about conditions on a future visit, and check the operator’s current information if this detail is part of your plan.

Otakinoyu lists a reservable private bath for ¥2,000 per hour, charged in addition to admission. The private-bath hours are 09:00–19:00, with last reception at 18:00; the guide also lists a towel and bath-towel rental set for ¥250. Ask the facility about current availability, the booking method, group size and the total cost for your party rather than assuming that the room or bath can be used without advance arrangements.

As a calculation using the listed categories, one adult paying the ¥1,200 day admission and using one hour of the ¥2,000 private bath would pay ¥3,200 before any towel rental or other purchase. That example does not establish the full charge for a group or a particular reservation. The FAQ says that re-entry after leaving normally requires another admission fee, so check with staff before exiting if you might want to return.

The facility guide lists parking for 100 vehicles. That is a stated capacity, not a reservation or assurance that a space will be available when you arrive. You can open a map search for Otakinoyu’s listed address, then compare the result with the facility’s address and check current road and access information.

Otakinoyu restaurant hours: check before planning a meal

The published weekday restaurant hours differ between two facility pages, so the available information does not establish which schedule will apply on your visit. The visitor guide lists 11:00–16:00, while the facility information page lists 11:00–18:00 with last orders at 17:30. Ask Otakinoyu for the current restaurant schedule before building a meal stop around either listing.

Gozanoyu and Sainokawara: two different bathing options

Gozanoyu is at Yubatake and provides indoor baths, while Sainokawara is an open-air bath. They are separate facilities with separate admission charges and seasonal opening hours, so visiting one does not include entry to the other. The Gozanoyu FAQ and Sainokawara guide are the relevant official pages for checking their facilities and current notices.

Gozanoyu is at 421 Kusatsu, Kusatsu-machi. Its listed adult admission is ¥900 and child admission is ¥450; it opens at 07:00 from 1 April through 30 November and at 08:00 from 1 December through 31 March, closing at 21:00 in both periods. Last entry is listed as 20:30, so the winter opening time is the main seasonal difference for an early visit.

Gozanoyu also lists a large room that bathing customers may use freely and a private medium-sized room for ¥2,000 per hour. The room is not a private bathing tub: the FAQ states that Gozanoyu has no private bath, open-air bath or sauna. The guide also lists a three-hour yukata-walk option for ¥2,500, including bathing and other stated services; confirm the current inclusions before purchase rather than assuming details not specified here.

The Gozanoyu FAQ says the facility is not barrier-free. If you have a particular mobility or access requirement, ask the facility about the route and arrangements that apply to you before travelling; do not assume that a room available to bath users provides an accessible route. A different facility may have different access conditions, so confirm directly with whichever bath you plan to use.

Sainokawara open-air bath is at 521-3 Kusatsu, Kusatsu-machi. Its listed admission is ¥800 for adults and ¥400 for children; it opens 07:00–20:00 from April through November and 09:00–20:00 from December through March. Last entry is 19:30, which is earlier than closing, so allow time to enter before that deadline.

The Sainokawara guide points drivers to the free Tenguyama No. 1 parking area, listed at 300 spaces. Capacity is not a reservation or a guarantee of a space, and the information does not establish conditions on your arrival day. Use a map search for the listed bath address and check the official facility notice for current access, weather-related information or operating changes.

Getting to Kusatsu Onsen and planning the return

Gunma tourism gives an estimate of about 25 minutes by bus from Naganohara-Kusatsuguchi Station to Kusatsu Onsen. JR Bus Kanto lists the route as its own service, but the available information here does not establish the fare or the last bus for your travel date. Check the operator’s timetable for the date and stations you intend to use rather than relying on an old fare or departure time.

A practical check is to open the JR Bus Kanto timetable and confirm both the outward journey and the return departure for your date. Then check the chosen bath’s official guide for its seasonal opening time, last entry and any temporary notice. If you plan to use Otakinoyu’s private bath, ask about availability and follow the facility’s current booking instructions.

The 25-minute figure covers the bus leg from Naganohara-Kusatsuguchi Station; it is not a total journey time from your starting point. It does not include your train journey to that station, time waiting for a connection, walking to a bath or the return trip. Allow for those parts when deciding whether a day visit fits your schedule, and check relevant weather, snow and road notices on the day if you are driving.

The parking figures are useful planning details but should not be treated as a guarantee of access. Otakinoyu’s guide lists 100 spaces, while the Sainokawara guide points to a free parking area with 300 spaces. For either facility, check current route information and actual availability rather than relying on the listed capacity alone.

Yubatake, Yumomi and staying overnight

Netsunoyu is in front of Yubatake, and Kusatsu Town describes traditional Yumomi and dance performances there. The town’s Yumomi and dance information establishes the venue and the type of performance, but the information used here does not establish a show time, ticket price or availability for your visit. Check the venue’s current schedule and ticket information separately before arranging your day around a performance.

For an overnight stay, compare the room, meals, bathing access, price and cancellation terms offered by a specific property for your dates and number of guests. The day-bath prices in this guide do not establish a ryokan room rate or availability. Ask the property directly about private bathing, tattoos, children and accessibility if any of those points matter to your party; a policy at one day-use bath does not establish the policy at every inn.

Otakinoyu, in particular, is a day-use facility and does not provide accommodation, according to its FAQ. Choose and book a separate property if you are staying overnight, and confirm what your accommodation price includes rather than assuming that meals or bathing are part of every rate. For general preparation, JGO!’s guides to onsen etiquette, onsen for beginners and private onsen offer broader questions to consider, while notices and staff instructions at the individual bath apply to that facility.

Frequently asked questions

Which Kusatsu day bath has the lowest listed adult admission?

Among the three facilities compared here, Sainokawara has the lowest listed adult admission at ¥800, followed by Gozanoyu at ¥900 and Otakinoyu at ¥1,200. These are separate facilities with different features, not different prices for an identical service. Check the Sainokawara guide, the Gozanoyu guide or the Otakinoyu guide for the latest notice before visiting.

Does Otakinoyu have a private bath?

Yes. Otakinoyu lists a reservable private bath at ¥2,000 per hour, with regular admission charged separately, and lists private-bath hours of 09:00–19:00 with last reception at 18:00. Ask the facility about availability, booking arrangements and the total for your group before relying on a particular time.

Does Gozanoyu offer a private bathing tub?

No. The Gozanoyu FAQ describes indoor baths and says there is no private bath, open-air bath or sauna. Its listed private medium-sized room is a separate room service, not a private bathing tub, so check the FAQ if you need to distinguish between the two.

What time does Sainokawara stop admitting visitors?

The Sainokawara guide lists last entry at 19:30 and closing at 20:00. Its opening time is seasonal: 07:00 from April through November and 09:00 from December through March. Check the official guide for a current notice before travelling.

How long is the bus ride from Naganohara-Kusatsuguchi Station?

Gunma tourism gives an approximate bus journey of 25 minutes from Naganohara-Kusatsuguchi Station to Kusatsu Onsen. That estimate does not include the journey to the station, a connection wait or the return trip. Confirm your date’s departure, fare and return service using the JR Bus Kanto timetable.

Can I stay overnight at Otakinoyu?

No. Otakinoyu’s FAQ describes it as a day-use facility, not accommodation. Book a separate place to stay and check its actual room price, vacancy and booking terms for your dates rather than treating a day-bath admission as a lodging rate.

Can I rely on a specific Yumomi performance time or ticket price?

The town information confirms that Netsunoyu is in front of Yubatake and that traditional Yumomi and dance performances are presented there. It does not establish a performance time or ticket price for your travel date. Check the venue’s current schedule and ticket information before making plans around a show.
