This video features a unique travel experience in Japan, where the creator explores a mobile sauna built onto the bed of a Japanese kei truck (軽トラ, keitora). The video documents her solo journey, testing out the sauna’s functionality while highlighting the quirks of mobile sauna culture. To make the experience even more memorable, after enjoying the heat of the sauna, she tries out an unconventional ‘cold bath’—by plunging into a lake right next to where the kei truck is parked.

Throughout her adventure, the creator provides her impressions of the mobile sauna setup, the process of heating the sauna, and the refreshing aftermath of cooling off in the lake. This video showcases the creativity and love of outdoor leisure that is becoming popular in Japan, especially among solo travelers looking for private and novel experiences. Saunas have gained a following in Japan, with innovations like mobile and pop-up saunas frequently appearing in both rural and suburban locales.

Japanese kei trucks are lightweight utility vehicles that are commonly modified for various outdoor purposes, from food trucks to mobile shelters. The ability to convert them into a portable sauna is a testament to Japanese resourcefulness and the nation’s enthusiasm for wellness trends. For those interested in similar adventures, lakeside saunas can be found in certain areas near natural parks and rural lakes, particularly in regions rich in onsen and outdoor activities. While the exact lake isn’t specified, such mobile sauna setups are gaining traction around Japan’s countryside.

For travelers wishing to experience a lakeside sauna in Japan, be sure to check for local regulations as well as opportunities to rent or participate in pop-up sauna events. The combination of enjoying a warm sauna and then cooling off in beautifully natural settings offers a unique twist to traditional bathing culture.
