Tokyo Minato City
An upgraded men-only sauna in Azabu Juban featuring two types of cold plunge baths and reserved seating
Ledian Spa Azabu Juban is a luxury sauna facility for men only in Minato City, Tokyo. Despite its excellent location just a short walk from Azabu-Juban Station, the sophisticated underground space feels like an adult hideaway that lets you completely forget the noise of the city. After warming your body all the way through in the dry sauna, where you can adjust the steam at your preferred timing, cool down sharply in the double cold plunge baths with different water temperatures. Its greatest appeal is the dedicated reserved seating that guarantees time to yourself. You can immerse yourself in deep relaxation without worrying about the crowds while feeling a gentle breeze.

A refined dry sauna with a uniquely designed stove built into the wall. Purple lighting creates a sense of the extraordinary, allowing you to spend calm, grown-up time here. Thanks to the auto-löyly function, you can adjust the steam at your preferred timing, letting you feel powerful heat and a pleasant level of humidity all over your body while sweating thoroughly from the core.

Just outside the sauna room, there are two cold plunge baths with different water temperatures. You can quickly tighten your overheated body with an icy cold bath, or cool down slowly in a milder cold bath. The nice part is that you can choose the level of coldness according to your condition and preference that day. Its crisp, refreshing chill wraps pleasantly around your whole body.
