Bathing & Water

Natural onsen water

Uses natural hot spring water

Outdoor BathNo

Open-air outdoor bath

Five 2024-2026 Google reviews consistently describe a single small indoor tub only. Two third-party onsen directories (nifty onsen, yuru-to.net) list an outdoor bath, but their addresses (626-2, 626-6) differ slightly from Google's 626 and their feature checklists read as generic; not used as evidence here.

Indoor BathYes

Enclosed indoor bathing area

Bathing Arrangements

Mixed BathingNo

Shared bathing area for all genders

No source mentions mixed bathing. This reviewer notes only the hair-dryer room seemed shared between genders, implying the bathing area itself is separated as usual for a small municipal bath.

Policies & Services

KidsYes

Welcomes children and families

WashingYes

Shower, wash stations, soap and shampoo provided

ParkingYes

On-site or nearby parking available

A second review separately confirms parking is available. Exact space counts vary across sources (5 to 10) and are not stored.

A bicarbonate spring led by sodium with a chloride layer, blended from Totsukawa wells No.2 and No.7. Hot at 58 °C and weakly alkaline, it carries the soft, skin-smoothing feel of a soda-style water with a salty edge that helps the heat linger after the bath.

About

Koshuyokujo Ikoi Hot Spring is a small municipal bath attached to a senior welfare hall in the Totsukawa onsen area, with one indoor tub built for a few bathers at a time. The hot-spring water is colorless and clear, with a faint sulfur smell and a slightly smooth feel on the skin, and it runs quite hot at the tap, so most people add cold water to cool it down. The washing area has basic soap and shampoo at the sinks, and there is free parking outside. It is a plain, workaday bath mostly used by people from the village rather than a tourist stop, and reviewers often have it to themselves.
