Alongside Hakone Onsen and Atami Onsen, it is called the “inner retreat of Tokyo” and enjoys high popularity as a hot spring travel destination due to its excellent accessibility of approximately 2 hours from central Tokyo, making it ideal for weekend getaways and vacations.

With 32 total hot spring sources and an abundant water volume of 3,573 liters per minute, the entire hot spring area provides high-quality hot spring experiences.
Geographical Characteristics of Kinugawa Onsen
Kinugawa Onsen is located along the Kinugawa River within Nikko National Park, with the hot spring town formed in a gorge area at an elevation of approximately 300 meters. The clear stream of the Kinugawa River and the mountains surrounding it create natural scenery that displays different faces throughout the seasons—spring’s fresh greenery, summer’s deep green, autumn’s red leaves, and winter’s snow scenery—offering different spectacular views depending on when you visit.
To the north lies Kawaji Onsen, and to the south are Nikko tourist attractions such as Nikko Toshogu Shrine, making it easy to plan travel combining hot springs and sightseeing.
History of Kinugawa Onsen | The Lineage of Famous Hot Springs Continuing from the Edo Period
Hot Spring Discovery and Use During the Edo Period
Kinugawa Onsen’s discovery is said to date to 1692 (Genroku 5) during the Edo period. Initially, as it was located in Nikko Goshinryo (the territory of Nikko Toshogu Shrine), bathing was limited to high-ranking daimyo and priests visiting Nikko. During this era, Kinugawa Onsen was called “Taki Onsen,” serving as an important rest stop during Nikko pilgrimages.
Due to its high effectiveness for burns, the saying “川治の傷, 滝の火傷” (injuries at Kawaji, burns at Taki—present-day Kinugawa Onsen) emerged alongside the northern Kawaji Onsen, establishing its reputation as a therapeutic hot spring.
Development and Opening to the General Public from the Meiji Era Onward
With the arrival of the Meiji era, Kinugawa Onsen was opened to ordinary people. This brought many travelers to the area, forming the foundation of it as a hot spring town. From the Taisho to early Showa periods, improved railway networks enhanced accessibility from Tokyo, establishing its status as the “inner retreat of Tokyo.”
During the post-war period of rapid economic growth, large hotels and inns were built successively, developing into one of the Kanto region’s major hot spring destinations. Today it has become a major tourist attraction attracting over 2 million overnight guests annually.
