Outdoor bath
✓ YesAn outdoor bath area (three tubs, though one waterfall/uchidase bath is sometimes out of order) is a major highlight for most, though one reviewer felt it's more a roofed pavilion without open sky than a true rotenburo.stated by 8 visitors · Jun 2025 – Jul 2026

Guide
What visitors add
Outdoor bath & sauna
Bath layout is one indoor bath plus three outdoor tubs including a waterfall (utase-yu) bath (6 reviewers); two reviewers note the outdoor area is roofed so you cannot see the sky. One reviewer explicitly notes there is no sauna. The utase-yu was reported broken by one reviewer in Jul 2025 and again by one in May 2026.
stated by 8 visitors · May 2025 – May 2026The water
The spring is a simple sulfur hot spring (4 reviewers); one quotes a source temperature of 41.5°C and one identifies the private source 'Oigami Onsen No. 2' used at 100%. Skin-feel praise recurs: one reviewer says moisture lasted over 6 hours, one describes lotion-like smoothness, and one saw yu-hana (mineral flakes) in both baths.
stated by 7 visitors · Jun 2025 – May 2026Price
Admission is 1,000 yen for adults (5 reviewers, Jun 2025-Mar 2026); one reviewer adds 500 yen for elementary-school children and free under 6, and one other used a 200-yen discount for showing a ski lift ticket.
stated by 6 visitors · Jun 2025 – Jun 2026Outdoor bath & sauna
Four reviewers describe a rose-filled bath (fresh roses floating in the water); two of them place it on the women's side, and one found apples floating instead in October.
stated by 5 visitors · Jul 2025 – Jul 2026Staffing
The facility is staffed and appears family-run — one reviewer says a couple handles everything from reception to the restaurant, one guesses it is self-managed family staff — and at least five reviewers praise the friendly reception/staff.
stated by 5 visitors · May 2025 – Jul 2026The water
Temperatures are moderate overall: one reviewer reports the indoor bath hot and the rotenburo mild (child-friendly), one says a 6-year-old could bathe without finding it hot, and one reports the men's side (with utase-yu) noticeably hotter than the women's side.
