This article introduces all the attractions of Tsuetatsu Onsen, from its history and water quality to tourist spots and access information.
History and Origin of Tsuetatsu Onsen
Legend of 1,800 Years of Hot Spring Discovery
The history of Tsuetatsu Onsen is ancient, dating back approximately 1,800 years. According to legend, Empress Jingu gave birth to Emperor Ojin in Tsukushi (present-day Fukuoka Prefecture), and it is said that she used the spiritual spring water gushing from Tsuetatsu as the baby’s first bath. This historic site still has a free outdoor bath called “Motoyu” today, beloved by local residents and tourists alike.
Origin of the Name “Tsuetatsu”
The hot spring’s name “Tsuetatsu” has a fascinating origin. It is said to derive from a poem composed by Kobo Daishi when he visited this place during the Heian period. The name conveys the meaning: “People who arrive here using walking sticks forget to take them when they leave after bathing in the hot spring, such is its healing power.” This legend demonstrates that Tsuetatsu Onsen had long been highly regarded as a hot spring resort for therapeutic purposes.
Development as a Hot Spring Resort
From the Edo period through the Meiji, Taisho, and Showa eras, Tsuetatsu Onsen flourished as the inner sanctum of Kyushu’s hot springs. It became particularly known as a hot spring resort where guests stayed for extended periods, with many people visiting for illness recovery and health improvement. The inns lining the gorge retain strong Showa-retro atmosphere today, creating a landscape that evokes the area’s former prosperity.
Water Quality and Effects of Tsuetatsu Onsen
Extremely High Temperature Source Spring of 98 Degrees
The greatest characteristic of Tsuetatsu Onsen is that its source spring temperature is approximately 98 degrees Celsius, making it exceptionally hot. This high-temperature self-spouting spring is known as one of Japan’s finest quality hot springs. Twenty-six source springs are scattered throughout the hot spring town, boasting abundant hot water supply. The steam rising throughout the town is produced by this high-temperature hot water, creating a landscape unique to Tsuetatsu Onsen.
Characteristics of Water Quality
Tsuetatsu Onsen’s water quality consists mainly of simple hot spring water and sodium-chloride springs. It is colorless and transparent with a smooth texture, earning it evaluation as a “beauty spring.” Since the high-temperature source is cooled to an appropriate temperature before use, the hot spring minerals are preserved in concentrated form, and skin becomes silky smooth after bathing.
Expected Health Benefits
Tsuetatsu Onsen’s therapeutic benefits are diverse. It is said to be effective for neuralgia, muscle pain, joint pain, frozen shoulder, motor paralysis, joint stiffness, bruises, sprains, chronic digestive disorders, hemorrhoids, poor circulation, post-illness recovery, fatigue recovery, and health promotion. Its long history of use as a therapeutic hot spring resort proves the effectiveness of its benefits.
Steam Bath Culture and the Charm of the Hot Spring Town
Notable “Steam Bath” and “Steam Rooms”
Unique to Tsuetatsu Onsen is the “steam bath” and “steam room” culture that utilizes the high temperature and abundant hot water of the source springs.
