Arima Grand Hotel - Private Onsen & Tattoo Policy

Steam rises from the ninth floor. Step out of the elevator into Unkai, the Sea of Clouds bathhouse, and the Rokko mountains fill the frame, close enough to trace the ridgeline while kinsen water glows rust-gold in the tubs below the windows. This is Arima's famous spring, and from the highest point in town, it comes with a view no other bath here can match.

Arima Grand Hotel builds bathing into every level. The 9th-floor Unkai is the headliner: wide windows, kinsen pools, mountain panorama. Underground, Yurari opens to outdoor kinsen baths at a quieter pace. The Aqua Terrace offers something else entirely: saunas, an outdoor heated pool, and a foot bath theater where you watch the mountains, swimsuit required for that section.

Tattooed guests should book one of the private options: a reservable private bath (kashikiri) or a guest room with its own open-air onsen bath, including a barrier-free private bath for step-free access. Traditional restrictions apply in the communal baths, but the private facilities draw from the same kinsen source with views to match.

• Private Kinsen Bathing: Reservable private baths and guest rooms with open-air tubs let tattooed guests soak in Arima's kinsen without entering the communal areas.
• Highest Vantage Point in Arima: The 9th-floor Unkai bathhouse overlooks the Rokko range and Arima's rooftops, the widest panorama of any bath in the onsen town.
• Barrier-Free Private Bath: A barrier-free private bath offers step-free access to a kinsen tub, a rarity for private onsen facilities in Japan.
• Aqua Terrace Between Soaks: An outdoor heated pool, several saunas, and a foot bath theater facing the mountains, a full half-day of bathing without repeating the same tub twice.

The rust-gold water catches the light first. In Unkai, the 9th-floor bathhouse, kinsen pools sit against panoramic windows — the Rokko range and Arima's tile rooftops spread below, and on clear days the view reaches the Tamba mountains. The water is warm and carries a weight you notice when you step in.

Underground, Yurari runs at a different tempo — outdoor kinsen baths open to the air, quieter than the main bathhouse above. Between soaking rounds, the Aqua Terrace shifts the pace: an outdoor heated pool, foot baths facing the mountains, and several saunas. Overnight guests get early morning Unkai access starting at five, when the valley is still dark and the kinsen pools catch the first light.
