Naniwa no Yu Natural Hot Spring

天然温泉なにわの湯

Tattoos not allowed (day visit)

Can you bathe here with a tattoo?

This is the question we built the site around, so we answer it per situation.

Visiting for the day

No — tattooed guests are turned away

Guests with tattoos are refused entry to the facility, so private baths are not an option either.

The serious water choice in central Osaka: 100% natural hot spring drawn from an ancient sea-floor layer, with a genuine free-flowing tub in the eighth-floor open-air area. The building is a tight city block ten minutes' walk from the subway, so what you see over the parapet is rooftops, and the rest space is modest.
