Does Mizu no Oto allow tattoos? In a private bath

Private bath only

Two springs under one roof at Kowakidani — Kowakidani water in the Suika wing, Miyanoshita water in the Suigetsu wing — each with a large bath and an open-air one, plus three free private open-air baths in the garden. The Suika rooms, renewed in 2025, have an open-air bath of their own.

The rooms in the Suika wing have an open-air bath of their own, and the garden holds three private open-air baths, free and unbooked, on the two springs the house draws. Book a Suika room and nothing needs covering.

What happens when you arrive

Skip the shared baths and reserve the private one the way this page describes; once the door is closed nobody is checking anything.

How we know

Confirmed Confirmed from official site — bath structure, not a tattoo policy

Read on: dormy-hotels.com/resort/hotels/mizunoto/ (rooms and hot spring pages)

Best for: Guests wanting a large renovated property with guaranteed private bathing plus multiple free kashikiri-buro

The operator publishes no tattoo rule either way, on any page read. In a bath you take by yourself that question does not arise — but do not read the silence as permission for the shared baths. One telephone call would settle those. Two wings: only the 水花の庄 rooms have a private bath - book that one

Check availability

Booking through this button costs you nothing extra and sends a small commission our way — it’s what keeps this guide free and every policy here checked. Thank you.
