Yuyado Tokino Niwa
Rooms with open-air bath

Gunma — 草津温泉
8 stays with a private bath · About 3.5-4 h from Tokyo (train + bus via Karuizawa or Naganohara-Kusatsuguchi)
The Yubatake steams in the middle of town — water so hot and strong they still cool it by hand, the old way.
95 dining spots and 116 places to stay are counted in 吾妻郡草津町 — the bath is one part of the evening, not the whole of it.
Every property listed here has a private bath — a reservable private bath or an open-air bath in your own room — so tattoos are a non-issue, and so is privacy.
