The famous Golden Spring can be enjoyed in the indoor baths and open-air baths of Ichinoyu, which is full of Japanese charm, and Ninoyu, which carries a hint of exotic elegance. The water turns a vivid brownish red when exposed to oxygen in the air, and is rich in iron and salt, giving it outstanding bathing benefits. The salt content forms a film on the body that helps prevent heat from escaping after bathing, so the warmth lasts for a long time. It is also known as the heat spring, and you can leisurely enjoy this superbly smooth, cloudy water.

Located in the 9th-floor garden, Sansou is a public bath styled after a nostalgic hot-spring resort. By opening the large glass doors between the indoor bath and the open-air bath, the entire bathing area transforms into a space with the pleasant openness of a semi-outdoor bath. Surrounded by the warmth of wood, you can slowly soak in Arima's proud cloudy Golden Spring and experience the ultimate comfort and deep healing of a place where it feels as though you are living in a hot-spring retreat.

Two luxurious private open-air baths with lush private gardens. In a completely private space where no one will disturb you, you can fully enjoy Arima's famous Golden Spring in baths drawn from the source. With family or loved ones, you can spend an incomparable moment quietly admiring the beautiful seasonal nature and the starry sky while soaking in the superb brownish-red water.
