Best Things to Do

  • 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.

How to Get 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 Attractions

Kusatsu pairs well with Ikaho Onsen, another historic Gunma hot spring town, or with the mountain scenery of Mount Tanigawa.
