Tamana Onsen is a historic hot-spring area in Tamana City, Kumamoto Prefecture, in the former province of Higo. The resort was once known as Riganji Onsen and flourished as the “inner retreat of the Mitsui family,” thanks in part to its proximity to Ōmuta in Fukuoka Prefecture, which prospered through coal mining.
Although the resort no longer enjoys the scale of its former prosperity and the number of inns has fallen to less than half its previous level, Tamana Onsen remains a destination for travelers seeking a relaxing hot-spring experience. Its long history, gentle waters, and traditional bathing facilities continue to attract visitors.
Tamana Onsen is said to have first emerged approximately 1,300 years ago. It is widely known as a “beauty bath” because of its gentle water, which is traditionally appreciated for its pleasant feel on the skin.
The spring water is classified as a mildly alkaline simple hot spring, with source temperatures of approximately 40–45°C. It is also known for containing relatively high levels of radium. Bathing is traditionally associated with relaxation and improved circulation, and the waters are popular among visitors who appreciate their skin-friendly qualities.
The hot-spring district extends along the Hangenoki River. According to the source information, the area has 11 inns and hotels, along with five facilities offering day-use bathing. A “hot-spring tour ticket” is available for overnight guests and day visitors, allowing them to enjoy more than one bath during their stay.
Shirasagi Footbath is located in Riganji Park. It opened in April 2004 as a free footbath available to everyone. Visitors can soak their feet in the warm water and take a break while exploring the hot-spring district.
Tamano-yu is a municipal public bathhouse in Tamana Onsen. It was renovated in 1992 and has long been used by local residents and travelers seeking an accessible day-use bathing facility. Its public character makes it an approachable way to experience the local hot springs without staying overnight at an inn.
The source information lists 11 inns and hotels operating in Tamana Onsen. Each offers its own atmosphere and facilities, giving visitors a range of options for a relaxing stay.
The listed accommodations are Motoyu Hikinō-sō Ryosō, Ōgonkan, Tsukasa Royal Hotel, Satoyama Resort Satsuki Bessō, Tamana Onsen Shōgen Sansō, Tamana Onsen Kinpōen, Tamana no Yuyado Chikusuien, Tamana Onsen Hotel Shirasagi, Tamana Family Onsen, Tamana Onsen Yamamomiji no Yado Hōhōen, and Tamana Onsen Riganji Onsen Hotel.
A local legend explains how the hot spring was discovered approximately 1,300 years ago. The story tells of a charcoal maker named Hikino Kogorō who lived in the area. One night, under a full moon, a princess from the capital received a message from Kannon, the Buddhist deity of compassion, telling her to marry Kogorō, who lived in the village of Hikino in the land of Higo.
The princess traveled to meet Kogorō, but he was so poor that he refused her, saying he did not even have rice stored for his meals. She gave him money and asked him to buy rice. On the way, however, Kogorō encountered a white heron. Unfamiliar with the value of money, he threw it at the bird.
The injured heron flew down into a rice field where steam was rising from the ground. After resting there for a while, the bird recovered and flew away. Curious about the place where the heron had landed, Kogorō investigated and discovered a hot spring bubbling from the earth.
The story is still passed down through Hikino Kogorō, who is enshrined at a shrine within the hot-spring area. The white heron in the legend is also reflected in the name of the free Shirasagi Footbath.
