Overview
The history of Hakone Onsen dates back to the Nara period (710-794). During the Edo period, it flourished as a post town on the Tokaido Highway, which connected Edo (modern-day Tokyo) and Kyoto, offering rest to weary travelers. Surrounded by mountains, each area—such as Hakone-Yumoto, Gora, Sengokuhara, and the Lake Ashi shore—boasts its own unique landscape and atmosphere.
Hakone's most defining feature is its diversity of spring water. Collectively known as the 'Hakone Nijutto' (20 Hot Springs of Hakone), the area is home to a wide range of onsen types, including simple, chloride, and sulfur springs, depending on the location. It is rare in Japan to find so many different water qualities in a single resort area, which continues to attract onsen enthusiasts.

Water Characteristics and Best Season
The temperature, color, and aroma of Hakone's onsen vary by area. The resort boasts an abundant supply of hot water, and many facilities offer gensen kakenagashi (water flowing directly from the source). You can enjoy the onsen with all your senses, from clear, colorless waters to the milky white sulfur springs found near Owakudani.
While the beautiful natural scenery can be enjoyed year-round, the area is particularly stunning in autumn (late October to November) when the mountains are ablaze with color, and in winter (January to February) when you can soak in an onsen while admiring a snow-covered landscape.
