Q. What is Shinzaemon no Yu?
Yunohana Chaya and Shinzaemon no Yu opened on April 21, 1999. The name is derived from a trading name called Iseya Shinzaemon that has survived for 11 generations since the Horeki era.
We set up Shinzaemon no Yu to inherit our ancestors’ spirit of “co-existence and co-prosperity living with nature and neighborhood” and share the joy of getting in touch with Zao Onsen and its abundant nature with many people.
Q. What kind of hot spring is there in the facility?
Our hot spring is a sulfurous spring with strong acidity. It has been used to improve fragile health, backed by the highland climate.
The hot spring is famous for its effect of making the skin beautiful and smooth as it is called “the hot water of beauty.”
・Nature of hot spring…Acid chloride spring containing sulfur, aluminum, and sulfate (strong acid sulfurous spring)
・Efficacy…Beautiful skin, cuts, burns, women’s diseases, physically weak children, arteriosclerosis, diabetes, high-blood pressure, and nerve pain.
Once you get in the hot spring, it reeks of the odor of sulfur. Please be careful because it stings a cut.
The hot spring is normally transparent, but it becomes cloudy when it comes in contact with the air or its turbidity changes as the mineral deposits are deposited or precipitated.
In our facility, three open-air hot spring baths are sulfurous springs, and Uchi Yu is an alkaline artificial hot spring containing many minerals.
If you wish to keep the efficacy of the hot spring, please towel your body dry lightly without washing off the hot spring water. If you are nervous about the odor of sulfur, please get in Uchi Yu or wash off the hot spring water with a shower.
At hot springs, soap can’t be used. Soap can only be used at Uchi Yu.
Q. What are the characteristics of the spring quality in the Zao area?
Zao Onsen is located at a high altitude of 880 meters on the west side of the Zao Mountain Range. It is a historic hot spring bath counted as one of the three major hot spring resorts on highlands in Oshu.
The hot springs in the Zao area pour out 15,000 liters of hot water per minute. As to spring quality, it is a strongly acidic sulfurous spring. The pH of the hot spring is 1.3, which makes it the second strongest acidic hot spring in Japan. This strong acidity can be proven by putting a towel in the hot spring bath. The towel will get frayed in two or three days in the hot spring bath.
In the Zao area, there are five groups of hot spring sources and as many as 47 hot spring sources. While there is a difference in water temperature, there is no big difference in efficacy.
It is said that Tamagawa Onsen in Akita is the strongest acidic hot spring in Japan at pH 1.2.
