Tsuru no Yu Onsen in the Okutama area of western Tokyo Metropolis is a hot spring in the remote mountain valleys of Okutama Town, at the headwaters of the Tama River within the Chichibu-Tama-Kai National Park, sharing its evocative name Crane Hot Spring with similarly named springs in Hokkaido, Akita, and Wakayama that together demonstrate the widespread use of the crane as a symbol of longevity and good fortune in Japanese hot spring culture. Okutama is the westernmost inhabited district of Tokyo Metropolis, a landscape of densely forested mountain gorges, clear mountain streams, and the vast Okutama reservoir that supplies much of the capital's drinking water, preserving a wilderness character remarkable for its proximity to one of the world's largest cities. The hot spring waters of Tsuru no Yu Onsen offer thermal bathing to hikers, campers, and mountain enthusiasts who journey to this remote but accessible corner of the national park seeking respite from urban life in the cool and clean mountain environment.
