Mountain onsen town
Think of Gunma as an inland mountain getaway, with Kusatsu as the anchor and Ikaho as the secondary classic stop.
Kanto
Gunma onsen guide
Gunma works because Kusatsu turns the whole town into part of the onsen experience, and Ikaho broadens the prefecture beyond one famous stop. It feels like a true mountain getaway, not just a bath break.
Main draw
Main draw of Gunma
Gunma is the place-first onsen escape, where Kusatsu and Ikaho bring mountain-town atmosphere, famous hot-spring culture, and a stronger getaway mood.
- Kusatsu makes the whole town part of the experience, with standout public baths and strong hot-spring identity.
- Ikaho adds another classic mountain-town stop, so Gunma feels broader than one famous name.
- Best for travellers who want scenery, town atmosphere, and a real getaway feeling around the soak.
