Tsutete Onsen is a historic hot spring resort in Oguni Town, Aso District, Kumamoto Prefecture. Part of the hot spring town extends into Hita City in neighboring Oita Prefecture. The area is known not only for the quality of its hot spring water but also for its distinctive atmosphere and long history, which have attracted tourists and people seeking therapeutic bathing for generations.
The entire area is surrounded by nature and lies within Yaba-Hita-Hikosan Quasi-National Park. The hot spring town stretches through a narrow valley along the Tsutete River, where traditional inns and steaming bathing facilities create a distinctive landscape.
Tsutete Onsen is a chloride spring, and the temperature of its naturally emerging hot water reaches approximately 100°C. Because the water is extremely hot at its source, hot spring facilities use it in ways appropriate for bathing.
The water has traditionally been associated with relief from sensitivity to cold, joint pain, and certain skin conditions. Its warming effect and the relaxing atmosphere of the hot spring town make it a popular place to unwind. These traditional descriptions should not be taken as a guarantee of medical benefits.
Nineteen inns line the valley around the Tsutete River. Accommodation ranges from large, upscale establishments to small, family-run inns and lodgings suited to visitors staying for therapeutic bathing. Guests can choose a place that suits their travel style and budget.
The town also offers a “Yumeguri Techo,” or hot spring-hopping booklet, which allows visitors to enjoy bathing at more than one location. Exploring the different baths is a way to experience the area’s long-standing hot spring culture.
Tsutete Onsen has five communal bathhouses: Motoyu, Yakushiyu, Gozenyu, Ryusen-yu, and Daini Shizen-yu. Each has its own atmosphere and offers a different way to experience the hot springs.
A park with a footbath is also available, providing a convenient place to warm your feet during a walk around town. Visiting the communal baths and footbath gives travelers an opportunity to experience the everyday bathing traditions of the local community.
Tsutete Onsen is said to have a history of approximately 1,800 years. According to local legend, the hot spring was used for the first bath of Emperor Ojin when he was an infant. The spring associated with this story is believed to have been located near Motoyu, one of the present-day communal bathhouses.
The current Motoyu, however, draws water from a different source. Even so, the legend remains an important part of the hot spring town’s historical identity.
The place name “Tsutete” is associated with a legend about the Buddhist monk Kobo Daishi, also known as Kukai. According to the story, people who arrived at the hot springs relying on walking sticks regained their health after bathing. When they left, they no longer needed their sticks and left them behind at the resort.
A traditional poem attributed to Kobo Daishi expresses this story:
“After bathing in the hot spring, my illness was cured. The stick I had leaned on, I leave standing here as I return.”
Another theory links the name to the place name “Tsue” in Hita City, Oita Prefecture. Geographer Toshiro Matsuo suggested that “Tsue” may mean a cliff, and that the name Tsutete could have a similar geographical origin.
During the Edo period (1603–1868), the site was known for a special bath reserved for the lord of the Kumamoto Domain. Today, Gozenyu, one of the communal bathhouses, recalls that history and is open to the public.
From the Meiji period (1868–1912) onward, Tsutete Onsen welcomed a number of cultural figures, including the poet Ujo Noguchi. Their visits helped establish the resort’s reputation beyond the local area.
In 1953, a major flood caused extensive damage across western Japan, and Tsutete Onsen was also seriously affected. The town recovered quickly and later flourished as “Kyushu’s inner retreat,” a popular destination for travelers seeking a relaxing hot spring holiday.
In more recent years, changing travel preferences and the growing popularity of nearby destinations such as Kurokawa Onsen contributed to a period of decline. In response, local efforts have focused on making better use of the town’s historic streetscape and distinctive steam baths. These efforts have gradually helped restore interest in Tsutete Onsen.
One of the town’s best-known events is the Tsutete Onsen Koinobori Festival. From April 1 through May 6, more than 3,000 colorful carp streamers are suspended across the Tsutete River, creating a spectacular sight that attracts visitors from throughout Japan.
The festival began around 1980 with approximately 40 carp streamers. Their number increased over the years, and the event has become one of the defining symbols of Tsutete Onsen.
Carp streamers are traditionally displayed in Japan around Children’s Day on May 5. They symbolize hopes for children’s healthy growth and success. At Tsutete Onsen, the streamers stretching above the river create a striking seasonal scene against the steep valley landscape.

When entering the hot spring town by car, the source article recommends taking the old road beside Tsutete Tunnel rather than driving through the tunnel itself.
Tsutete Onsen brings together a long history, traditional communal baths, riverside inns, and the natural beauty of a steep mountain valley. Its legends about Emperor Ojin and Kobo Daishi add historical and cultural interest, while the town’s bathing facilities offer a chance to experience a traditional part of Japanese travel culture.
Spring is an especially lively time to visit, when thousands of carp streamers fill the sky above the river during the Koinobori Festival. Whether you come for the hot springs, the festival, or a leisurely walk through the valley, Tsutete Onsen offers a distinctive glimpse into the history and atmosphere of rural Kyushu.
