About Iyo No Tojiba Kisuke no Yu
"Iyo No Tojiba Kisuke no Yu" is a large day-use bath complex in Matsuyama, Ehime Prefecture. It has two hot spring sources drawn from 1,700 m below the deepest part of the Dogo Onsen area, and its signature Tsubaki-no-Yu bath lets guests enjoy the alkaline simple mildly radioactive spring, with a pH of 9.4, directly from the source. In the men’s baths, the Fuujin Sauna, which accommodates up to 40 people and is among the largest in the prefecture, is joined by two outdoor Oni Saunas, "Aoi" and "Homura," along with a tsubo-style cold plunge bath with water in the single-digit Celsius range. With a high-concentration carbonated spring and a rock bed bath, both among the largest in western Japan, the facility offers a full-day healing experience in a prime location right in front of JR Matsuyama Station.
Hot SpringONSEN
No. 2 Spring Tsubaki-no-Yu
A beautifying bath using No. 2 Spring drawn directly from the source at 1,700 m below the deepest part of the Dogo Onsen area. The highly alkaline water with a pH of 9.4 provides a cleansing effect that gently dissolves dead skin cells, leaving the skin smooth after bathing. A faint sulfur scent and silky texture let you experience authentic Dogo waters. It is also known as the "beauty bath" and the "neuralgia bath," and is expected to help with stroke rehabilitation as well as hypertension and arteriosclerosis.
FeaturesFree-flow from source
No. 2 Source Spring
A mildly radioactive sodium chloride spring containing abundant sodium and chloride, which forms a salt film on the skin and delivers excellent warming and moisturizing effects. The body stays warm even after bathing and is less likely to cool down, so it may help improve sensitivity to cold and neuralgia, and promote blood circulation.
SaunaSAUNA
Fuujin Sauna
A large tower-style sauna with one of the highest capacities in the prefecture. A dedicated stove packed with sauna stones made from Kikuma tiles, including the "Onimaru" and "Onidama" stones fired by tile artisans from Kikuma, Ehime, creates deep, enveloping heat in the room. During the automatic löyly at every hour on the hour and half past, called "Fuujin Heat Wave," a massive amount of steam spreads at once, and the perceived temperature rises above 100°C. Self-löyly and tea löyly using locally produced tea are also available, and regular staff-led aufguss events are held as well.
Oni Sauna "Aoi"
One of the Oni Sauna rooms located in the outdoor area. As the name "Aoi" suggests, it has a calm blue-themed atmosphere, and auto-löyly is activated at 10 and 40 minutes past every hour. Unlike the indoor Fuujin Sauna, this smaller space fills with steam, creating a concentrated sense of heat. With a tsubo-style cold plunge bath in the single-digit Celsius range and easy access to the outdoor air-bath area, it is designed to make hot-and-cold contrast bathing seamless.
Oni Sauna "Homura"
A high-temperature sauna themed around the red ogre, located in the outdoor Oni Sauna area. Auto-löyly is activated at 20 and 50 minutes past every hour, and the intense heat of 110°C dominates the small space. Used together with the Aoi Sauna, it allows you to switch freely between two levels of heat, 90°C and 110°C. For advanced sauna lovers who prefer very high temperatures, this room serves as the finishing step after the Fuujin Sauna, heating the body to the limit outdoors.
Aibi Sauna
A dry sauna exclusive to the women’s bath area, born from a collaboration with Misaki Ai Farm in Sada-misaki, Ehime. Craftsmen hand-apply a special coating, infused with ingredients extracted from tadeai, onto each bench made of domestic hinoki cypress, allowing the calming effect of indigo to gently fill the room from the wood surface. Indigo tones are also carried through the walls and lighting, creating a space designed to work softly on all five senses.
Mist Sauna "Kasumi"
A low-temperature, high-humidity mist sauna installed in the women’s bath area. The fine mist gently wraps around the whole body, and because it is less irritating to the skin, it is easy to relax in for a long time. It is ideal for those who are not fond of high-temperature saunas or for those who want to prepare their skin as the finishing touch to a sauna session. It is expected to have beauty and weight-loss benefits, and functions as part of a careful bathing experience combined with hot spring bathing.
Cold BathCOLD BATH
Seireisen / Shio Seisen
After the sauna, cool down in two kinds of cold plunge baths using cold spring water rich in salt components. The gentle, beginner-friendly "Shio Seisen" and the sharply cold, advanced-user-oriented "Seireisen" are available. The salt coats the skin, enhances warmth retention, and helps prevent chill after bathing while pleasantly tightening the whole body. Choose your preferred level of coolness and be led into an exquisite state of totonou.
