Takaragawa Onsen Osenkaku, Outdoor hot spring complex in Tone district, Japan
The facility presents four large outdoor baths distributed along the Takara River, surrounded by mountains and dense forest vegetation.
The establishment traces back over three centuries, with the main building constructed from ancient pine trees in 1955 and the first annex dating to 1936.
The onsen maintains the Japanese bathing tradition of mixed-gender outdoor baths where guests wear provided bathing garments while soaking in mineral-rich waters.
Located two hours from Tokyo, the facility provides round-the-clock access to thermal pools for overnight guests, with separate areas for day visitors.
Each season transforms the bathing experience, from snow-covered winter landscapes to autumn foliage reflections in the streaming waters.

Hot springs form where geothermal activity or groundwater systems naturally heat water. This collection features such springs across volcanic zones, mountain ranges and remote areas on all continents. Each location has distinct mineral content and temperatures shaped by its underlying geology. In Iceland, the Blue Lagoon offers mineral-rich water in a lava field near Grindavík, while Deildartunguhver in the west produces one of Europe's most powerful hot springs. Pamukkale in Turkey's Denizli region displays terraced limestone pools formed by calcium-rich thermal water. The Széchenyi Baths in Budapest draw water exceeding 160 degrees Fahrenheit (70 degrees Celsius) from nearly 4,300 feet (1,300 meters) below ground. In Wyoming, Yellowstone's Grand Prismatic Spring shows intense colors produced by its size and thermophilic bacteria. Japan hosts numerous onsen, including Takaragawa in Gunma Prefecture along a river and Yubatake in Kusatsu with visible high mineral output. Jigokudani Monkey Park in Nagano is known for macaques that bathe there. In North America, the collection spans Banff Upper Hot Springs in Alberta, Chena Hot Springs in Alaska and smaller sites such as Baker Hot Springs in Utah. Grutas Tolantongo in Hidalgo, Mexico, combines warm pools with river flows in a canyon. New Zealand's geothermal zones appear at Champagne Pool in Waiotapu and Hell's Gate Park near Rotorua.
