Nagano — 湯田中温泉
12 stays with a private bath · In Yamanouchi Town, Nagano — the old spa strip below Shiga Kogen, beside Shibu Onsen
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.
Nagano · Getting there: In Yamanouchi Town, Nagano — the old spa strip below Shiga Kogen, beside Shibu Onsen
Every guest room's unit bath runs on natural hot spring water here — a Taisho-era source found bubbling up through the riverbed sand — and the shared scenic open-air bath looks over the town.
A small family inn where the hinoki bath is yours alone: write your room number on the board when it's free and lock the door behind you. The water is the inn's own 100% natural spring.
Until 7pm the inn's bath runs on reservations only — pick a 55-minute slot at check-in and the hinoki bath is entirely yours, filled with natural spring water poured straight from the source: no heating, no added water.
Three baths under one old roof: a big stone open-air bath, a yuya-style bath, and a reservable bath built from 400-year-old Kiso hinoki — the reservable one is the quiet way to take Seifuso's spring alone.
One barrier-free special room carries its own natural hot spring bath, and the inn draws on its own source — the shared baths pour the same water, free-flowing.
A six-room inn built around lamplight. Its two baths — one wooden, one stone, each with an indoor tub and an open-air tub — are chartered privately in the evening, and guests can also use sister inn Yorozuya's famous Momoyama bath.
Four rooms open onto their own free-flowing open-air baths, fed from four sources including Jigokudani, and there is a reservable bath too — 50 minutes, booked at check-in or ahead. The source runs at 95°C, so it is tempered with cold groundwater.
Two rooftop reservable baths, Kocho-no-yu and Hotaru-no-yu, look over the whole town — 40 minutes a session, fully reserved. Some rooms carry their own open-air baths, and everything pours 100% free-flowing spring water.
The renewed suites put a semi-open-air bath on the room, pouring free-flowing spring water — the private soak is built into the stay.
The outdoor onsen turns private in the evening: 30-minute slots from 7pm to 9pm that every guest can reserve — the bath itself, not a side tub, in a wooden inn that has stood in Yudanaka for generations.
Private SPA Bon is a reservable bath wing of its own — sauna, cold bath and a free-flowing natural spring bath, bookable in two-hour slots, day visitors included. Every room's bath runs on natural onsen too, and the Momoyama bath hall is a registered cultural property.
Two big reservable semi-open-air baths — one rock, one hinoki — and both are free. The water is 100% source water drawn from three springs and kept constantly flowing.
