History and Characteristics of Hakone Yumoto Hot Spring
Ancient History of the Thermal Waters Continuing from the Nara Period
The opening of Hakone Yumoto Hot Spring is said to date back to the 10th year of Tenpyo (738), making it the oldest hot spring among the seventeen hot springs of Hakone. It is believed to have been discovered by a Buddhist priest named Shaku Jojobō, and “Sōyu,” a naturally spouting hot spring source at the entrance of Kumano Shrine, continues to flow as the original source even today.
During the Edo period, the reputation of Hakone Yumoto Hot Spring grew even higher, with hot spring water being transported as “tribute hot water” to the Tokugawa shogunate, becoming a celebrated thermal water. Interestingly, until the Meiji era, hot spring development was prohibited due to a “joint ownership agreement,” with only the single source of “Sōyu” continuing for that period. This strict management is said to have contributed to preserving the quality of the hot spring.
Central Presence in the Hakone Hot Spring Resort

Numerous inns and hotels line the area around Hakone Yumoto Station, showing the bustle of a hot spring town.
Due to its geographical location at the foot of the Hakone volcano, abundant hot spring water flows out, allowing many facilities to possess their own hot spring sources. Multiple facilities boast exceptional hot water output by Hakone standards, making it possible to experience authentic hot spring bathing with 100% natural hot spring water in an open-air style.
Spring Quality and Effects of Hakone Yumoto Hot Spring

Hot springs such as “Hakone Yumoto Hot Spring” and “Tonosawa Hot Spring,” positioned at the foot of the Hakone volcano, tend to have particularly high proportions of chloride springs.
Chloride springs are also called “heat water,” characterized by high heat retention effects as salt adheres to the skin after bathing, making it difficult to cool down quickly. Additionally, with a skin-friendly spring quality, even those with sensitive skin can bathe with confidence, making it supported by a wide age range.
