Guide
What visitors add
Price
Adult admission was 520 yen (8 distinct reviewers cite 520 yen; one reviewer says 530 yen). Pricing was tiered by residency and age: one reviewer details city seniors at 100 yen and non-city adults 520 yen / seniors 310 yen; two other reviewers confirm residents and non-residents paid different rates.
stated by 9 visitors · Apr 2025 – Jan 2026Towels, soap & lockers
Body soap was provided but shampoo was not (9 distinct reviewers state this); shampoo/conditioner pouches could be bought at reception for 100 yen (4 reviewers). Dryers were available per one reviewer; shoe boxes had keys per another.
stated by 9 visitors · Jan 2025 – Jan 2026The water
Billed as natural hot spring water (3 reviewers mention 天然温泉 signage, one noting '源泉100%' was also posted); several reviewers (4 distinct) praise skin-smoothing, well-warming water, and one long-term repeat visitor guesses it is alkaline. However, 2 distinct reviewers report a strong chlorine smell, and the repeat visitor says the onsen smell and smooth-skin feel had disappeared by Feb 2026, wondering if the source is depleting.
stated by 7 visitors · Jan 2025 – Mar 2026Outdoor bath & sauna
There was no rotenburo, no sauna, and no cold-water bath: 6 distinct reviewers state some or all of this; the facility had only two indoor tubs (one a jacuzzi, per two reviewers; one reviewer notes both tubs at the same temperature) and one reviewer mentions a small outdoor-air rest space fitting about 3 people.
stated by 7 visitors · Jan 2025 – Jan 2026Day-use visits
PERMANENTLY CLOSED: one reviewer states the facility closed for good on 14 May 2026 and has been replaced by a new nearby facility ('Yu-topia MidoMoSpa'); 4 other distinct reviews from Jan-Jun 2026 confirm closure or imminent closure, two of them mentioning a planned rebuild/renewal.
stated by 5 visitors · Jan 2026 – Jun 2026Staffing
The facility had a staffed reception desk (selling shampoo pouches and collecting payment/receipts, per 3 distinct reviewers); one reviewer singles out the site manager for exceptional diligence.
