JAPAN SAUNA FESTIVAL 2026

About this event

"JAPAN SAUNA FESTIVAL 2026" is one of Japan's largest outdoor sauna festivals, held over two days on Saturday, September 26 and Sunday, September 27, 2026, at Tamagawa Miharashi Park in Kawasaki, Kanagawa. It offers diverse sauna experiences that everyone—from sauna beginners to avid sauna enthusiasts—can enjoy. The venue features a standard sauna area, the 100-person extra-large sauna tent that was immensely popular last year, and a curated area of specialty saunas that will impress dedicated sauna aficionados. In addition, ice-cold water baths equipped with chillers and Aufguss events hosted by special guests are scheduled. Alongside the sauna area, a free-admission Summer Festival Area will be set up during the event period, featuring food, market stalls, and carnival games. This allows accompanying guests who do not use the saunas to fully enjoy the festive atmosphere together. Unique collaboration saunas, such as the Keikyu Line Sauna and the IYOSHI COLA Sauna, will also make an appearance, offering high-impact experiences available nowhere else.
