Candeo Hotels Osaka The Tower - A Tattoo-Friendly Hot Spring in Osaka City, Osaka

Thirty-one floors up, the city drops away. The outdoor infinity bath on the rooftop of Candeo Hotels Osaka The Tower sits 127 meters above street level — Guinness-certified as the highest of its kind — and from the edge of the water, Osaka Castle and the downtown skyline float at eye level while you soak.

The SkySpa takes up the top floor, split into gender-separated areas with indoor baths, a cold plunge, and a Finnish-style auto-loyly sauna. The outdoor infinity tub is the centerpiece. At night, the city lights spread out beneath you. At sunrise, the sky shifts over the rooftops before anyone else in the hotel is awake. The spa runs from afternoon through to late morning, so both sessions are possible in a single stay.

This is not a rural hot spring — it's a modern urban bathhouse designed around the view. Tattoos are permitted in all bathing areas, confirmed by hotel policy and backed by consistent guest accounts from 2024 through 2025. If you want a city-center base in Osaka with a rooftop soak that no traditional onsen can match, this is the one.

• Highest Infinity Bath in Japan: The 31st-floor outdoor tub sits 127 meters above ground — Guinness-certified — with unobstructed views of Osaka Castle and the city skyline.
• Tattoos Permitted, No Restrictions: Hotel policy explicitly allows tattoos in all Sky Spa areas, and recent guests confirm tattooed bathers use the baths without covers or questions.
• Afternoon-to-Dawn Bathing: The spa opens in the afternoon and runs through to late morning, giving overnight guests access during both golden hour and the quiet pre-dawn window.
• Sauna Circuit at Altitude: A Finnish iki-stove sauna with auto-loyly steam cycles, a cold plunge, and outdoor air at rooftop height — the full loop without leaving the 31st floor.

The infinity bath has no rim on the city side — just water meeting sky, with Osaka spreading out below. It's heated water rather than natural spring, clear and unscented, but the setting does the work that mineral content would do elsewhere. Inside, the baths are modern and spacious, with enough shower stations that you rarely wait. The sauna runs at around 80°C with automatic steam every fifteen minutes, and the cold plunge drops the contrast hard before you step back outside to cool down in the open air. The outdoor section closes when winds pick up, so calm evenings are the best sessions. After dark, the city lights replace the skyline view, and the water reflects them back.
