Omuta Tennen Onsen Saiko no Yu

大牟田天然温泉最高の湯

The guiding concept here is simple: “the most comfortable space possible.”Over time, the facility has evolved, adding four types of saunas, a manga street with over 10,000 volumes, and a library and relaxation room.
Fifteen different types of baths—including hinoki baths, walking baths, and electric baths—offer something new with every visit.What truly elevates the experience, however, are the saunas.Each of the men’s and women’s areas features four distinct sauna styles: hybrid, steam, medication, and barrel saunas.This diverse lineup promises a deeply refreshing “totonou” experience for both body and mind.
