Things to Do in Gunma: Kusatsu, Ikaho and Outdoor Plans

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

Gunma offers several different kinds of day out: a hot-spring-town walk in Kusatsu, bathing at Ikaho’s open-air bath, or a separately arranged outdoor activity in Minakami. These are not interchangeable plans. The baths have different facilities, prices and opening schedules, while river activities and winter sports require checks with the specific operator or venue.

For a first visit, choose the main activity before adding stops around it. Check the relevant official page for your date, keep the address or meeting point with your plans, and leave time for the visit itself rather than treating a bath pass or a list of attractions as a schedule. The details below were checked against official sources on 4 November 2026; seasonal descriptions and destination introductions are not guarantees that a particular activity is operating on a specific date.

1. Explore Kusatsu around the Yubatake

Kusatsu’s Yubatake is a useful focus for a town walk. The Gunma tourism guide introduces the Yubatake’s evening illumination, strolling in yukata and the traditional yumomi demonstration at Netsunoyu. These are different ways to experience the town, so decide whether you want to watch a performance, take a walk, visit a bath, or combine some of them rather than assuming one activity includes the others. See the official Kusatsu destination guide.

Yumomi is described as a traditional way of cooling hot-spring water with boards. Watching a demonstration is not the same as bathing, and the destination guide does not establish the current show schedule or fee. Check Netsunoyu’s current information before arranging a visit around a particular performance; do not rely on an assumed start time.

The guide also introduces the area around Sainokawara Park and its open-air bathing. Treat that as a separate choice from the Yubatake stroll: allow time for the walk and, if you plan to bathe, for changing and any other needs you have at the facility. A combined ticket is worthwhile only if its included facilities fit your actual plan, so check the tourism association’s current information to confirm which places a pass covers.

A simple planning sequence is to choose the main activity, check its current conditions, and then add the other town experiences that fit around it. For example, a visitor who mainly wants a bath should confirm the bath’s admission and hours first, while someone most interested in yumomi should check the performance information before choosing a visit time. The Yubatake illumination and yukata stroll make an evening walk another option, but neither replaces checking the opening details of a paid facility.

2. Compare Ohtakinoyu and Ikaho by facilities

Ohtakinoyu and Ikaho’s open-air bath offer different bathing conditions. Ohtakinoyu lists an indoor facility schedule, towel rental and private-bath reception hours; Ikaho’s open-air bath uses flowing Kogane-no-yu water and has no washing area. Compare what each place provides, not just the admission prices, before deciding which suits your visit.

Ohtakinoyu is open from 09:00 to 21:00, with final admission at 20:00. Admission is ¥1,200 for adults and ¥600 for children, and a towel-and-bath-towel rental set is ¥250. The facility lists credit-card and electronic-payment support; private-bath reception is listed from 09:00 to 19:00, with final reception at 18:00, so ask the facility about the exact private-bath arrangements. These details are on Ohtakinoyu’s official guide.

At the listed prices, an adult admission plus one towel rental set comes to ¥1,450; the rental is separate from admission. If you do not need the rental, do not add it to your estimate. The private-bath reception window is also separate from the general facility hours, so arriving before the overall final admission time does not by itself establish that private-bath reception is still available.

Ikaho’s open-air bath is at 581 Ikaho, Ikaho-machi, Shibukawa. Adult admission is ¥600, and elementary-school children and younger pay ¥300. It uses continuously flowing Kogane-no-yu water, but it has no washing area, making it a different type of visit rather than simply a less expensive substitute for Ohtakinoyu. The tourism association gives a five-minute walk from Kajika Bridge parking; check the facility name and address before following a map result. See the Ikaho Onsen Tourism Association’s official bath information.

If washing facilities are important to you, take the Ikaho conditions into account before setting out. If you choose Ikaho for the open-air bath, plan around its seasonal hours and its regular closure rules, which are detailed in the next section. The two places also have different payment and rental information in the supplied official listings, so do not assume one facility’s conditions apply to the other.

3. Make the season part of the bathing plan

Ikaho’s open-air bath lists different opening times by season. From April through September it is open 09:00–18:00; from October through March it is open 10:00–18:00. Final admission is 17:30. In practical terms, someone visiting in November should use the later morning opening, not the summer schedule.

The regular closure is the first and third Thursday. The facility is open on public holidays and has no closures in August, according to the tourism association. Check the calendar for your actual date rather than relying only on the weekday pattern, particularly if a public holiday affects your plan. The bath’s seasonal schedule and closure information are published on the official Ikaho open-air bath page.

Kusatsu also has seasonal choices beyond bathing. The official destination guide introduces beginner and intermediate ski courses at Kusatsu Onsen Ski Resort and describes stays combining snow sports with hot springs. It also points to summer cotton grass at Yoshigadaira wetlands and autumn foliage around Kusatsu. These are useful ways to match a visit to an interest or season, but a general destination introduction does not confirm current operating conditions for a particular date.

Treat seasonal attractions as reasons to investigate, not as confirmation that a facility, route or activity will be available. Check current information for the specific venue or service before committing your day to it. For baths, confirm the date-specific opening window; for skiing or a seasonal outdoor visit, look for the venue’s own current operating information rather than assuming that a seasonal description guarantees access.

4. Choose outdoor Gunma as a separate activity day

Minakami is introduced by the Japan National Tourism Organization as a destination for canyoning, rafting, canoeing and hiking. Those descriptions can help you decide what kind of day you want, but they do not give the price, age eligibility or booking conditions for a specific operator. Before choosing transport or paying, identify the actual provider and check the details of its product for your date. JNTO’s Gunma guide introduces these activities and regional alternatives.

For a river or canyon activity, ask the operator about participant age, equipment, meeting point, weather cancellation and the actual route. The general Minakami destination overview does not establish those conditions. Keep the provider’s meeting information with your booking and confirm it before arranging the rest of the day; a regional activity description is not a substitute for the operator’s instructions.

Winter sports also need venue-specific checking. JNTO notes that Gunma has ski resorts, while the Kusatsu destination guide introduces beginner and intermediate courses and the possibility of combining skiing with a hot-spring stay. These descriptions do not establish current operating dates or conditions for a particular resort. Confirm current information with the relevant venue before planning around a ski day.

If you prefer a culture-focused plan, JNTO introduces Tomioka Silk Mill as a destination for industrial history, Takasaki daruma as a craft souvenir, and Isesaki kasuri as a traditional local textile. These give you alternatives to a day of rafting or canyoning, but the destination overview does not supply the opening hours, workshop prices or transfer times needed to build a detailed schedule. Check those details separately if you want to visit a particular site or take part in an activity.

Keep a cultural visit and an outdoor booking as separate choices until you have checked the transport and time needed for both. In particular, do not assume that the space left after a late bath is enough for another excursion: the sources here do not provide the transfer times or return-service details for a combined itinerary. A good sequence is to secure the activity’s actual meeting and finish details first, then decide whether another stop fits.

5. Compare costs, time and conditions

The table brings together the published admission prices and operating windows for the named baths. A price applies to the named service and stated age band; it does not include transport, meals or purchases unless the row explicitly says so. These official details were checked on 4 November 2026, and the Kusatsu price revision noted below took effect on 1 September 2025.

Ohtakinoyu’s admission and rental are separate line items, while Ikaho’s lower adult admission is for a different facility with no washing area. Use the price that matches the experience you actually want rather than comparing admission figures alone. The official Ohtakinoyu guide provides its current listed hours, prices and payment information; the Ikaho tourism association provides the open-air bath’s price and conditions.

The Kusatsu tourism association’s published revision lists Gozanoyu at ¥900 for adults and ¥450 for children, and the three-bath pass at ¥2,100 for adults and ¥1,050 for children. Those revised prices took effect on 1 September 2025. Before buying a pass, check which facilities it applies to and whether their hours suit your visit; the number of baths named in a pass does not tell you whether you will have time or reason to use them all. Check the Kusatsu Onsen Tourism Association’s official price-revision information.

Build the rest of your budget separately. None of the prices in the table includes inter-town transport or meals, and Ohtakinoyu’s towel rental is explicitly an extra charge. For any activity without a published price here, use the actual operator or facility’s current information instead of substituting an old or unrelated figure.

Make the booking match the visit

Choose Ohtakinoyu if its listed facility conditions and schedule suit you, or Ikaho if you want its open-air bath and accept that there is no washing area. Ohtakinoyu’s general final admission and private-bath final reception are different times, so check the right one for the service you intend to use. Ikaho’s winter opening begins at 10:00, and its final admission is 17:30.

For Minakami rafting, canyoning, canoeing or hiking, look for a named operator and confirm the product’s price, age rule, equipment, meeting point, route and weather-cancellation policy directly. The destination page introduces the activities but does not establish any of those operator-specific booking details. Do not treat a general destination description as a confirmed reservation or as assurance that an activity is running on your chosen date.

For yumomi, check Netsunoyu’s current programme and fee before arranging your visit around a demonstration. The available destination information explains the tradition but does not confirm the current performance time or price. This same principle applies to cultural visits and seasonal activities: use the relevant site’s current information for the date-specific details that the regional overview does not supply.

6. Save an address as well as a map result

For Ikaho’s open-air bath, the listed address is 581 Ikaho, Ikaho-machi, Shibukawa, and the tourism association gives a five-minute walk from Kajika Bridge parking. You can open a map search for the Ikaho open-air bath and its address. Match the map result to the official facility name before following directions, because a pin for a wider district may not identify the facility entrance.

Save the address in text as well as in your map app. That gives you a name and location to check if a map loads slowly or returns several similarly named results. For any other bath, event or outdoor activity, use the exact name and address or meeting point supplied by its official provider rather than assuming that a destination-area search points to the right entrance.

The existing map search for Maebashi, Gunma is a broad city search, not a route to one of the baths or an outdoor meeting point. It can be useful as a place-name search, but it does not provide a verified route, journey time or connection to Kusatsu, Ikaho or Minakami. Check transport separately for your date and keep the relevant return information with your plan.

7. Questions before you go

Is Ikaho’s open-air bath suitable if I need a washing area?

No washing area is listed at Ikaho’s open-air bath, so choose another facility if washing facilities are essential to your visit. The bath is described as using continuously flowing Kogane-no-yu water, which is a different facility feature and does not change the washing-area limitation. Check the official facility information before setting out if you have a specific bathing requirement.

What is yumomi, and can I plan around a particular show?

Yumomi is described as a traditional method of cooling hot-spring water with boards. Netsunoyu presents demonstrations, making it a separate activity from bathing at a hot-spring facility. The available destination information does not confirm the current performance fee or start time, so check Netsunoyu’s current programme before planning around a particular show.

How should I choose a Minakami outdoor activity?

Start by choosing among the activities introduced for Minakami—canyoning, rafting, canoeing or hiking—then identify a provider offering the activity you want. Ask that operator about price, age eligibility, equipment, meeting place, actual route and weather cancellation before paying. The regional destination guide introduces the activity types but does not establish the booking conditions for individual operators.

Can I combine a bath with a cultural or outdoor visit?

Possibly, but first check each stop’s opening information, meeting point and access for your date. The sources here do not provide enough transport timings to confirm a particular combined itinerary or return service. Plan the main booked activity or bath first, then add another stop only when you have confirmed that the movement between them works.

Should I choose Kusatsu, Ikaho or Minakami?

Choose Kusatsu for a hot-spring-town focus around the Yubatake, with options that include a town walk, yumomi at Netsunoyu, baths and seasonal interests described by the destination guide. Choose Ikaho if its open-air bath, Kogane-no-yu and stated access conditions fit what you want, while remembering that it has no washing area. Choose Minakami for a separately arranged outdoor activity, but base the plan on an actual operator’s product and conditions rather than the regional overview alone.
