Guide
What visitors add
Private bath
The entire facility is private-rental (kashikiri): two self-contained units, each with its own tatami rest room doubling as changing room, toilet, and washbasin, so only two parties can use the place at once. One reviewer says which unit you get is assigned by time slot. More than ten reviewers describe having baths, rest room, and changing area entirely to their party. Most reviewers count three baths per unit — indoor, semi-open-air, and open-air (one unit reportedly has a large kama/cauldron bath, popular with children).
stated by 12 visitors · Jul 2021 – Jun 2026Staffing
Run hands-on by the owner — two reviewers describe a one-man operation handling cleaning and management (one other refers to an owner couple). Hospitality is a recurring theme: five distinct reviewers mention free drinks or refreshments (canned juice on departure twice, juice for children, a canned beer brought with a chilled glass, tea for a walk-in guest). One reviewer (Jan 2025) says the business has faced harassment (abusive posts, complaint calls, winter-tire incidents) and its continued operation has been precarious.
stated by 9 visitors · Oct 2021 – Aug 2026Day-use visits
Day use is sold in timed slots: reviewers mention 1-hour, 1.5-hour, and 2-hour sessions (one regular always books 90 minutes; one reviewer who took the 1-hour slot found it too short; one recommends about 1.5 hours). One reviewer was told changeover cleaning between parties takes 30 minutes. Pricing varies by duration and party size per one reviewer.
stated by 7 visitors · Oct 2021 – Feb 2026Price
No reviewer states an actual price, but seven distinct reviewers independently call it reasonable/cheap — one notes it is cheaper than comparable options even on weekends and that the per-person cost drops with larger groups; another says the price depends on duration and number of people.
stated by 7 visitors · Aug 2021 – Mar 2026The water
The water is soft and skin-friendly: one reviewer guesses a weakly alkaline spring that invites long soaks, another says it is gentle enough for people with sensitive skin, and a third reports silky-smooth skin afterwards. Temperature reports conflict: two reviewers describe it as on the cool/lukewarm side (one explicitly says it does not suit lovers of hot water; another found the open-air bath lukewarm but the middle bath just right), while two others call the water hot.
stated by 7 visitors · Jul 2021 – Nov 2025Towels, soap & lockers
Three reviewers report a free face towel is included (one says it is yours to take home); bath towels are rental only — one reviewer paid 100 yen per bath towel, another brought their own. Two reviewers confirm shampoo/conditioner/body soap and a hair dryer are provided. Food is not served — bringing your own food and drink is allowed and encouraged (four reviewers; one notes a shared hot-water pot and microwave, and soft drinks/alcohol are sold on site).
