What you’ll find
A free, hidden-away Kusatsu public bath fed by the Yubatake source with fully source-fed acidic sulfur water and very hot temperatures, but overwhelmingly reported as restricted to town residents only since a COVID-era policy that has persisted for years.

Guide
What visitors add
For foreign visitors
Access for non-locals has changed repeatedly and recent reports conflict. Pre-COVID (Dec 2019) one reviewer said tourists could quietly use it if well-mannered. From 2020 to 2024, ten distinct reviews report it was closed to non-townspeople (COVID-era signs; one reviewer in Oct 2023 was told to leave). In 2025 reports split: three reviews (Aug-Oct 2025) say it was locked or locals-only, while the two most recent reviews (Dec 2025) say non-townspeople can now enter but there are townspeople-only time slots. Check locally before relying on entry.
stated by 16 visitors · Dec 2019 – Dec 2025The water
The bath uses the Yubatake source (four distinct reviews); one reviewer gives the spring type as acidic, sulfur-aluminum-sulfate-chloride spring. One reviewer describes clear, smooth water that leaves skin slippery. Temperature reports conflict: four reviews call it very hot (one measured 47C at the coolest corner in Dec 2019), while six others found the temperature just right or naturally moderated (one explains the offset between the source outlet and the tub cools it to a suitable temperature).
stated by 11 visitors · Apr 2017 – Dec 2025Towels, soap & lockers
Two reviewers note there is a toilet (one specifies Western-style) and that the bathing and changing rooms are roomier than the narrow entrance suggests; two reviewers report there is no parking lot. No review mentions towels, soap, or lockers being provided.
stated by 4 visitors · Aug 2017 – Nov 2023Price
Three distinct reviews describe it as one of Kusatsu's free communal baths (no admission fee).
stated by 3 visitors · Dec 2019 – Dec 2024Day-use visits
One reviewer (Dec 2025) warns there are townspeople-only time slots; one reviewer (Aug 2025) found the door locked at just past 10am on a Monday. No published opening hours appear in the reviews.
stated by 2 visitors · Aug 2025 – Dec 2025Water handling
One reviewer (2017) states the bath is completely free-flowing (kanzen kakenagashi); another (2018) notes diluting with water is possible but you should ask other bathers first, implying unrecirculated source water.
