How we know

Confirmed we contacted the property directly (September 2026)

Read on: the property, contacted directly, September 2026

Best for: Rooftop tubs with a view of Kochi Castle unique in the city, if a small or mid-size tattoo is covered by a seal you bring yourself.

Men bathe on the 14th-floor roof of the main building, women on the 9th-floor roof of the annex, and the hotel says the castle view from the tub is unique in the city. There is no indoor bath and no sauna. 16:00 to 23:00, with a men-only morning bath 06:00 to 09:00. The water is 人工光明石温泉, a mineral-salt tablet bath, not a hot spring; the hotel lists the ten salts it dissolves and says the result is “just like” a natural spring.
