The birthplace of super sento. An open-air bath with night views and a stunning Bazooka löyly experience
Aichi Nagoya City
"Tenku SPA HILLS Ryusenji no Yu Nagoya Moriyama Honten" is a prestigious facility known as the birthplace of super sento and high-concentration carbonated springs. Taking advantage of its elevated location, the observation open-air bath offers a sweeping view of Nagoya's cityscape. The sauna area features two types: the "Bazooka löyly Sauna," which blasts out powerful hot air, and the "Medi Sauna," where self-löyly is possible. The cold baths are also diverse, including one in the single-digit range and one with bubble jets, delivering an overwhelmingly large-scale bathing experience.
TypeNatural Hot Spring
An alkaline simple spring rising from 2,000 m underground. The water is colorless and transparent, with a gentle softness that is kind to the skin. In the observation open-air bath, you can soak in the natural hot spring while gazing at a night view that sparkles like scattered jewels, making for a truly luxurious moment worthy of being called the "heavenly bath." A high-concentration carbonated spring is also available.
