Gunma Travel Guide
Gunma is a strong Japan travel destination for onsen towns, mountains, hiking, silk history, and countryside scenery north of Tokyo.
Quick facts
- Best for: onsen towns, mountains, hiking, silk history
- Recommended stay: 1 to 3 days
- Best season: Spring, autumn, and key local festival seasons
- Main bases: Kusatsu Onsen, Ikaho Onsen, Tomioka, Minakami
Why visit Gunma
Gunma is Tokyo’s hot spring back garden, and its resorts are the working kind rather than the polished kind. Kusatsu Onsen is built around the Yubatake, an open wooden channel in the middle of town where the water is cooled in the air before it reaches the baths — you smell the sulphur before you see it. Ikaho Onsen climbs a long stone stairway lined with inns and shops. For something other than bathing, Mount Tanigawa offers a ropeway into serious mountain scenery, and the Tomioka Silk Mill, a UNESCO World Heritage site, preserves the brick factory where Japan’s modern silk industry began.
Getting to Gunma
Gunma is close to Tokyo on the Joetsu and Hokuriku Shinkansen lines, and Kusatsu is reached by limited express and bus in a few hours — close enough that many people come for one night. The prefecture is mountainous, so the resorts sit apart from each other and combining two in a trip means either a car or a long bus day. Winter brings snow and skiing to the north, and the hot springs are at their best in exactly that weather.
Top Attractions in Gunma
Kusatsu Onsen
Kusatsu Onsen is one of Japan's most famous hot spring towns, built around the steaming Yubatake hot water field in the mountains of Gunma, with some of the highest natural spring output in the country.
- Price
- Free to walk around the Yubatake and town center; individual public baths and the Sainokawara Open-Air Bath charge a small entry fee.
- Time needed
- Half a day for a walking visit; an overnight stay is common to fully enjoy the onsen.
View practical details
- Best time
- Winter (December to March) for skiing and snow atmosphere, though the hot springs are enjoyable year-round.
- Good for
- Onsen enthusiasts, couples, families, and winter sports visitors.
What to do
- Walk around the Yubatake hot water field at the center of town and watch the mineral-rich water flow.
- Watch a yumomi water-cooling performance, where staff stir the hot water with wooden paddles.
- Soak in public baths such as Otakinoyu or Gozanoyu, or try the outdoor Sainokawara Rotenburo.
- Combine the visit with skiing at the nearby Kusatsu Kokusai Ski Resort in winter or hiking in the surrounding hills in warmer months.
Tickets and fees
Checked in July 2026: walking around the Yubatake area is free. Public bathhouses such as Otakinoyu and Gozanoyu, and the Sainokawara Open-Air Bath, each charge their own entry fee, generally a few hundred yen. Confirm current prices and hours locally since they can change seasonally.
Getting there
From Tokyo, take a JR limited express or shinkansen connection toward Naganohara-Kusatsuguchi Station, then a JR bus about 25 minutes to Kusatsu Onsen Bus Terminal (roughly 2.5 to 3 hours total). Direct highway buses also run from Shinjuku Bus Terminal, taking about 3 hours 45 minutes.
Nearby
Kusatsu pairs well with Ikaho Onsen, another historic Gunma hot spring town, or with the mountain scenery of Mount Tanigawa.
Ikaho Onsen
Ikaho Onsen is a historic hot spring town in the mountains of Gunma, built around 365 stone steps lined with shops and inns, with roots going back to the 8th century and a shrine at the top of the stairs.
- Price
- The stone steps and the free footbath are free. At city-run Ishidan no Yu, standard adult admission is 800 yen; Shibukawa residents pay 500 yen.
- Time needed
- Allow two to three hours for the stone steps, footbath, Ikaho Shrine, and Kajika Bridge; stay longer for a bath or ryokan night.
View practical details
- Best time
- Year-round for the onsen town; Kajika Bridge is especially photogenic with autumn maples. Check current illumination dates before a seasonal trip.
- Good for
- Hot spring lovers, couples, first-time onsen visitors, and an easy overnight or day trip from Tokyo.
What to do
- Climb the 365 stone steps slowly, stopping at the small shops, cafes, and rest areas along the route.
- Use the free footbath at step 212, then continue to Ikaho Shrine at the top of the steps.
- From the shrine, take the relatively flat five-minute walk to the vermilion Kajika Bridge; continue toward the open-air bath only if that extra walk suits your plan.
- Choose a bath deliberately: Ishidan no Yu sits on the steps and uses Kogane no Yu, while ryokan day-use rules and prices vary by property.
Tickets and fees
Checked in August 2026: the stone steps and footbath are free. City-run Ishidan no Yu is open 10:00–20:00, with final entry at 19:30. Standard adult admission is 800 yen (500 yen for Shibukawa residents); children, eligible seniors, and visitors with disabilities have separate rates. It normally closes on the second and fourth Tuesday, shifting to the next weekday after a public holiday; maintenance and seasonal exceptions can apply, so check the city page before visiting.
Getting there
For the clearest rail-to-bus arrival, travel to Shibukawa Station and take a Kan-etsu Transportation bus bound for Ikaho Onsen from Stop No. 3 outside the station. The ride takes about 25 minutes; pay as you leave with cash or a transportation IC card. Get off at Ishidangaiguchi, directly in front of the bottom of the stone steps, where lockers and visitor information are available. Direct highway-bus options from Tokyo also exist; confirm the current operator timetable before booking.
Nearby
Ikaho pairs naturally with Kusatsu Onsen for a two-hot-spring Gunma trip, or with the UNESCO-listed Tomioka Silk Mill for a history-focused day.
Mount Tanigawa
Mount Tanigawa is a dramatic 1,977-meter peak on the Gunma-Niigata border, ranked among Japan's 100 Famous Mountains, with a ropeway that lifts casual visitors to alpine views and a serious ridge route for experienced hikers beyond.
- Price
- Paid ropeway. Round-trip adult tickets are commonly cited around yen 2,000 to 2,100; prices and lift add-ons vary by source and season.
- Time needed
- About 1 hour for the ropeway and observation deck only; 5 to 6 hours round trip for the Tenjindaira ridge hike.
View practical details
- Best time
- July to October for hiking season; the ropeway itself runs year-round, including for autumn foliage and winter snow views.
- Good for
- Hikers, mountain scenery seekers, and day-trippers from Tokyo wanting an alpine experience without an overnight stay.
What to do
- Ride the Tanigawadake Ropeway from Doaiguchi Station up to Tenjindaira Station for panoramic mountain views.
- Walk the short path around the Tenjintoge Observation Deck if you are not planning a full hike.
- Hike the roughly 6.4 km round-trip ridge route from Tenjindaira for experienced hikers, allowing 5 to 6 hours.
- Submit a climbing plan at the box near the ropeway ticket booths if heading beyond the observation deck.
Tickets and fees
Checked in July 2026: the ropeway is a paid ride, with round-trip adult fares commonly cited around yen 2,000 to 2,100 depending on the source and any lift add-ons. Confirm the current fare and operating hours on the official Tanigawadake Ropeway site before visiting, especially in winter.
Getting there
From Tokyo Station, take the Joetsu Shinkansen to Jomo-Kogen Station (under 2 hours), then a bus to the Tanigawadake Ropeway base station. Alternatively, a local bus runs between Minakami Station and the ropeway base about once an hour.
Nearby
Pair the mountain with a soak at Kusatsu Onsen or Ikaho Onsen to rest after a day on the ridge.
