意味

Sauna — hot steam bathing that has become a massive wellness trend in Japan, far beyond simple bathing.

サウナ culture in Japan underwent a renaissance in the late 2010s-2020s, transforming from a niche activity associated with older men into a trendy lifestyle pursuit. The サウナブーム (sauna boom) was driven by the manga and TV drama サ道 (Sadō, 'The Way of Sauna'), dedicated sauna facilities, and social media. Modern Japanese sauna culture revolves around the ritual of alternating between hot sauna, cold water plunge, and outdoor rest (外気浴) to achieve ととのう (the bliss state). Sauna vocabulary, etiquette, and facility reviews have become their own cultural ecosystem.
