Yamaai-no-Yado KIYASUYA

Yamaai-no-Yado KIYASUYA uses two types of spring sources. The main source is a "Sodium-Chloride Spring" (temperature 76.9°C) drawn from Sujiyu Onsen Supply Co. It is a hot spring containing salt, which has a bactericidal effect, and bathing in it can reduce Cuts and other skin surface problems. So it is called "Hot spring for Cuts". When you soak in a salty hot spring, the salty water covers your body like a pack. This pack blocks the sweat glands (small tubular structures of the skin that produce sweat), so the body temperature drops slowly after bathing, and the body feels warm for a long time. For this reason, Chloride Springs are also called "Hot spring for warmth". It may help improve Peripheral circulatory failure and Sensitivity to cold.
Additionally, this salt pack also reduces Skin dryness after the bath.
Chloride Spring is also said to have a Relaxing effect due to its unique properties. It is also said to be effective for mental problems such as Depression.
To sum up, the unique indications of the Chloride Spring are Cuts, Peripheral circulatory failure, Sensitivity to cold, Depression, and Dry skin.
The components that do not appear in the name of the spring are also noteworthy. The spring contains 157 mg of Metasilicic acid per kilogram of spring water, more than three times the standard value (50 mg/kg). It is a so-called Natural moisturizing component, and is sometimes used as some skin lotion products. After bathing in hot spring water, it helps to keep the skin moisturized. The presence of metasilicic acid is one of the conditions for being called "Hot spring for beauty". Metaboric acid also contains 37.1 mg, which is more than seven times the standard value (5 mg). Due to its Skin cleansing effects, it is thought to be effective in treating acne and other skin surface problems. This component is also used in some eye drops. Lithium ions are also worth noting. It has cleared the "Hot spring" standard value of 1 mg/kg or more. Said to have an Antidepressant effect. The other source is supplied by the Sujiyu Bunto Association, and is used mainly in the men's and women's large public baths, where it is mixed with the above source. The quality of the spring is "Simple Hot Spring" (spring temperature 91.5°C) with a pH of 7.0 (Neutral). It is said to be a gentle spring with low irritation. Due to the quality of the spring, which is safe for everyone from children to the elderly, it is also called "Hot spring for family". The large public baths for men and women are supplied with sodium chloride spring water and simple hot spring water at a ratio of approximately 7:3. The spring water (Simple Hot Spring) supplied by the Sujiyu Bunto Association is a "Artificial Hot Springs", which is a type of hot spring that is created by applying water from a mountain stream to hot spring steam that has gushed out from the ground and is full of hot spring components. This is the same system as that used in the hot springs gushing out of Owakudani in Hakone, Kanagawa Prefecture.
The two sources of hot spring water used here total approximately 100 liters per minute, and the water is free-flowing. Free-flowing hot-spring water means that the hot spring water is poured into the baths and any overflow is discarded as it is. The maximum capacity of this inn is 30 people, so the amount of hot spring water used per person is calculated to be about 3.3 liters/minute. As a rule of thumb, 1 liter/minute per person is considered sufficient for hygienic use of hot spring water without circulation, which means that the inn has more than three times that amount of hot spring water. The temperature of the hot spring is controlled by adjusting the volume of hot water poured into the bathtub by temperature. In the summer, well water is sometimes added to the water because of the high temperature of the spring, but the inn tries to make the water 100% from the source as much as possible. It would not be an exaggeration to say that this inn shows us what is the wonders of hot springs and what is the use of hot water with special care.
