Best Areas To Stay In Gunma For Onsens

Gunma is a large area so it can be hard to decide where to stay. While some places in Gunma are famous for alpine skiing, there are a few hot spots for onsens. To best equip you for your trip to Gunma, we highlighted three popular areas to visit so you’re close to hot springs.

  • Kusatsu – Three hours outside Tokyo, Kusatsu is most renowned for its hot spring baths. Visit the Yubatake in the town center, a hot water field, and Kusatsu’s symbol. Then try the hot spring baths at Sainokawara Park, Japan’s largest outdoor onsen. For something different, check out the zoo at Kusatsu Tropical Wonderland enclosed in a unique dome. There are a few hotels with onsens here, but Kusatsu Onsen Eidaya and Urakusatsu TOU are the most highly rated by guests.
  • Minakami – Thanks to its proximity to the Tone River, Minakami is full of exciting water activities. From kayaking and rafting to hot spring baths, you have plenty to do here. If you travel to Minakami specifically for the hot springs, check into Bettei Senjyuan, where all rooms come with private onsens. Sampling the local specialty, “hegi soba noodles”, is a must too.
  • Ikaho Onsen Stone Steps – Ikaho is your place for a weekend getaway. Watch cherry blossom at Ikaho Green Bokujo, a working farm where kids can interact with animals too. Another attraction is the Ikaho Onsen Stone Steps. Climbing the 365 steps to the Ikaho Shrine is said to bring you good luck. For couples, you’ll thoroughly enjoy Kaichoro for its excellent food and views.

Best Time To Visit Gunma

All four seasons in Gunma promise new delights to tourists. To make the most of the warmer weather, visit between May and October. However, the peak season in Gunma is during the winter from December to March. Despite the crowds, taking a hot spring bath in the snow will be an unforgettable experience. Come and watch spring and fall foliage change in Gunma too. Plan a road trip along the Japanese Romantic Road and take many photos of the ever-changing scenery.
