TTNE announces global expansion of Japanese sauna culture

TTNE Co., Ltd., a Japanese sauna creative group, has announced its global expansion strategy following presentations at the World Sauna Forum 2026 in Finland and the International Sauna Congress 2026 in Norway.

The company aims to promote Japanese sauna culture by blending its unique “KATA” (framework) with local traditions, architecture, and technology rather than simply exporting Japanese-style facilities. TTNE seeks to create new sauna experiences by integrating the culture with various sectors such as fashion, science, and regional history.

During the congress in Oslo, the group presented the theme “Japanese Sauna Culture to the World,” highlighting the experience design for the “Taiyo no Tsubomi” sauna at the 2025 Osaka-Kansai Expo.
