What you’ll find
A small city-run day bath halfway up Ikaho Onsen's famous stone steps, with a single indoor tub, a step-viewing terrace instead of an outdoor bath, and no sauna; despite the historic Ikaho spring source, several reviewers detect added chlorine rather than a true kakenagashi feel, and the locker deposit is not refunded.

What visitors add
Price
Adult admission is 800 yen (at least 10 distinct reviews, Dec 2025 - Aug 2026); elementary-age children 400 yen per one reviewer; seniors 65+ pay 400 yen per 2 reviewers (a third says seniors are half price); Shibukawa citizens get a 500-yen rate per 2 reviewers. One reviewer notes the price was in the 400s a few years ago before being roughly doubled.
stated by 12 visitors · Dec 2025 – Aug 2026Outdoor bath & sauna
There is no outdoor bath and no sauna — a single indoor tub only (men's tub fits about 10 people per one reviewer): at least 8 distinct reviews confirm this; instead there is a wood-deck terrace/veranda where bathers cool off overlooking the stone-step street (5+ reviews). One visitor was told to pay again after stepping out to the courtyard, with no prior warning.
stated by 9 visitors · Nov 2025 – Aug 2026The water
Water color descriptions conflict: 2 reviewers saw golden/brownish iron-scented water, 2 saw colorless-transparent water (one with faint tea-colored cloudiness), and 1 explicitly says it was not brown and barely smelled of iron — likely reflecting the mixed-source supply, so do not count on the famous golden color. Two reviewers additionally report cleanliness problems (floating hair/debris; poor cleaning).
stated by 7 visitors · Nov 2025 – Aug 2026Towels, soap & lockers
Soap and shampoo are provided per 3 reviews (one Dec 2025 reviewer says none is provided — the outlier; one notes the women's side has only rinse-in shampoo she found harsh). Towels are not free: one paid 200 yen for a towel at the ticket machine, another saw towels sold around 500 yen, and a third brought her own because rentals are paid.
stated by 7 visitors · Dec 2025 – Aug 2026Price
Several reviewers (at least 5) judge 800 yen overpriced for a single indoor tub with no rotenburo or sauna, while one reviewer explicitly argues it is worth it; value perception is the facility's most contested point.
stated by 6 visitors · Jan 2026 – Aug 2026The water
One reviewer transcribes the posted analysis: calcium-sodium sulfate / hydrogen-carbonate / chloride spring (hypotonic, neutral), source 41.2 degrees C; bath temperature reports cluster at 41-43 degrees C (4 reviewers) with outliers calling it slightly hot, lukewarm-pleasant, or too tepid. One reviewer says the tub blends the 黄金の湯 (golden) and 白銀の湯 (silver) sources.
