Diving into the Luxurious Realm of Top 5 Outdoor Saunas Sweeping the Globe

Fusion of Modernism and Nostalgia - Japanese Rotenburo

Japan, with its deep-rooted culture of onsen (hot springs), has a unique take on outdoor saunas. They are hardly the classic wooden boxes. Instead, rotenburo or open-air baths are often made of rocks and set amidst natural landscapes. This fusion of modern vibrant design aesthetics and nostalgic feelings of traditional Japanese bathhouses offers one-of-a-kind luxury to the sauna devotees.

At the Hoshinoya Tokyo, their rotenburo—a rooftop outdoor hot spring—is a true testament to Japan's devotion to innovative yet traditional wellness. The hot spring's water is pumped from 1,500 meters underground, thus providing a high-quality, authentic onsen experience right in the heart of Tokyo city.
