Gin No Yu Onsen - A Tattoo-Friendly Hot Spring in Arima Onsen, Hyogo

The water is clear. After everything you've heard about Arima's famous rust-brown kinsen, the first thing you notice at Gin No Yu is that you can see the bottom of the tub. This is the other Arima spring — ginsen, a carbonated water that comes out cool from the ground and gets heated before it reaches you. Where kinsen is dense and iron-heavy, ginsen is light, fizzy, almost effervescent against your skin.

Gin No Yu sits uphill from Arima's main drag, past the temples and shrines in the quieter end of town. It's a compact public bathhouse — indoor baths only, no frills, the kind of sotoyu where locals and visitors share the same space. The building takes its design cues from the rock baths where Toyotomi Hideyoshi supposedly soaked four centuries ago, though the scale is modest: one main pool, a steam sauna, a jacuzzi section, and a waterfall shower.

If you're spending a day in Arima and want to try both spring types, Gin No Yu is the calmer half. Tattooed guests bathe openly here — recent visitors confirm no questions asked, no second looks.

• Arima's Other Spring: Ginsen is Arima's transparent, carbonated water — the counterpoint to the brown kinsen at nearby Kin No Yu. A dual ticket covers both bathhouses for a full Arima tasting.
• Tattoos Accepted, No Covers Needed: Recent reviews from 2024 through 2026 confirm tattooed bathers in the communal bath without any issue or intervention from staff.
• Quieter Than Kin No Yu: The uphill location near Arima's temple district draws fewer visitors — guests consistently describe a more relaxed, less crowded soak.
• Steam Sauna and Jacuzzi: Beyond the main pool, the steam sauna and bubbling jacuzzi section round out a longer visit — uncommon amenities for a public bathhouse at this price point.

The water hits hotter than you expect. Step into the main tub and the heat registers immediately — this is ginsen heated well above its cool source temperature, and regulars say it takes a moment to settle in. The water itself is transparent and light, with a faint carbonated quality that leaves skin feeling smooth and clean afterward.

The main bath splits into two zones: a still section and a bubbling jacuzzi half with jets rising from below. A waterfall shower (打たせ湯) runs along one wall for working out shoulder tension. The steam sauna is small — a handful of people at a time — and runs cooler than a dry sauna, more of a slow warm-up than an intense session. Everything is indoors. No rotenburo here, no views. What Gin No Yu offers instead is simplicity: hot water, quiet space, and the particular after-bath lightness that ginsen is known for in Arima.
