Yuno Onsen: Day-Use Hot Spring Baths & Prices
A quiet hot spring village that opens out along the upper Yoichi River in Shunan City, Yamaguchi Prefecture. Counted with Yuda Onsen and Nagato Yumoto Onsen among the "Three Famous Springs of Bocho," it has an alkaline sulfur spring that is rare along the Seto Inland Sea coast. It is a small hot spring resort with only three inns, but all three accept day-use bathing, and each differs in how it handles the water and in its fees. It has also been called the "inner parlor of Tokuyama," and is loved as a moist, beautifying bath.
The Sacred Spring That Cooled Emperor Ojin's Fever
The origins of Yuno Onsen go back to a legend of Empress Jingu. In the ninth year of Emperor Chuai's reign, Empress Jingu's party, on the way back from Silla, met a storm in the Suo-nada Sea and, escaping the danger, landed at Shiraga-no-Ura (present-day Heta, Shunan City). While they were sheltering in a house near Funakami Shrine in Tonomi Village, the newborn Prince Homutawake (later Emperor Ojin) fell gravely ill with a fever. An attendant heard from the villagers about a sacred spring in the area, and when they drew that water and offered it to the prince, his fever is said to have suddenly come down. The empress's party is said to have stayed three days before departing, and that sacred spring is held to be today's Yuno Onsen.
Entering the Meiji era, the flow of people increased as it became a place of recuperation for soldiers wounded and sick in the Sino-Japanese and Russo-Japanese wars, and it grew stronger in character as a toji (curative bathing) resort. As a hot spring with more than 1,700 years of history, it still carries the banner of "waters for health and beautiful skin."
The Differences between the Three Inns
The source name is Shunan City-owned Source No. 3. The spring quality is a weakly radioactive, alkaline simple sulfur spring, with a high alkaline pH of 9.35 to 9.5. The combination of a sulfur spring that is also alkaline is rare even nationwide; the water is colorless and transparent, tasteless, with a faint smell of hydrogen sulfide. Because the source temperature is on the low side at 32 to 33 degrees C, it is warmed to around 41 degrees C for the tubs.
"Shisuien" is an inn built around a Japanese garden, with a bubble bath, jet bath and open-air bath in addition to the large communal bath. "Hozanen" is an inn with detached buildings that opened a new large bath, "Howa no Yu," in September 2024, and in addition to an open-air rock bath and reclining bath it has two ceramic tubs supplied with free-flowing source water. "Yuya Haruruoto" is a day-use-only facility created by renovating an inn that opened in 1965, and its private hot spring baths "Kouko" and "Tsubotsubo" are both free-flowing from the source.
Highlights
The quiet riverside setting wrapped in rich nature is its charm. The smooth, silky feel slowly unwinds everyday fatigue.
Seasonal Enjoyment
