BETTEI SENJUAN

The "Bettei Senjuan" uses a mixture of three private sources of spring water.
The names of the three sources are "Kuraoki-no-Yu", "Kajika-no-Yu", and "Senju-no-Yu", and the mixing ratio is 5 : 8 : 12.
All sources are power-pumped. In other words, they are hot springs obtained by boring (digging a deep, narrow hole in the ground) and drilling.
Gushing volume: approx. 360 liters/minute (total of three private sources). The maximum capacity of the inn is 50 people, which means that 7.2 liters/minute of spring water can be used per person by simple calculation.
Although there are various theories, it is said that a gush rate of about 1 liter/minute per person is necessary to enjoy bathing in clean conditions.
If the amount of water gushing out is less than this, facilities such as circulators and chlorine sterilization will be required.
At the "Bettei Senjuan", even by the numbers, you can see that there are more than enough springs available.
The inn has a total of 18 rooms, all with open-air baths. In addition to the guest room open-air baths, the Ichi-no-Kura and Sen-no-Kura public baths for men and women, respectively, have open-air baths called "Suzumushi-no-Yu" and "Hotaru-no-Yu". Of course, all bathtubs are free-flowing hot spring water.
In simple words, the source of spring water is poured into the bathtub and the overflowing water is poured directly down the drain and discarded. Although it can be said that this is an extravagant use of hot water, it can also be said that this method of using hot water is the most effective way to demonstrate the inherent power of the hot spring. The name of the spring quality is "Calcium Sodium-Sulfate Chloride Hot Spring".
First of all, if we speak of the features in the order of their ingredients, the first one is the expression "Hot spring for strokes" from "Sulfate spring".
This is due to its ability to prevent arteriosclerosis and lower blood pressure.
The second is commonly known as "Hot spring for anti-aging" or "Hot spring for rejuvenation" due to its skin revitalizing effects.
This is because Calcium-Sulfate spring stimulates the elasticity of the skin and prevents wrinkles.
The third feature of "Sulfate Springs" is that, like "Chloride Springs," they are also called "Hot springs for cuts" because they are effective in reducing surface skin problems such as cuts, burns, and acne.
The sterilizing effect of the salt content is what makes it effective against cuts and scars.
The fourth feature, "Chloride spring" is said to be "Hot spring for warmth" and "Hot spring for heat" because the salts adhere to the skin, preventing evaporation of sweat, thus creating a moisturizing effect and making it difficult to cool down. It is recommended for those who suffers from sensitivity to cold.
Fifth, it should not be overlooked that the hot spring is weak alkaline with a pH of 8.4.
Since human skin is generally slightly acidic, soaking in this hot spring reacts with the surface of the skin, making it smooth and creamy to the touch.
This texture occurs because the dead skin cells on the skin surface are dissolved. After the bath, the skin will be slippery and smooth.
The "Sulfate spring" and "Weak alkaline hot spring" make it possible to assert that the hot spring at "Bettei Senjuan" is a "Hot spring for beauty".
However, although it depends on the ratio of dissolved substances, in general, after bathing in an alkaline hot spring, the dead skin cells are exfoliated and the skin becomes smooth, but it tends to dry out quickly.
But the hot spring here at "Bettei Senjuan" is also a "Chloride spring", so it acts like a moisturizer due to the coating effect of salt.
This is why it is said to be a good finishing touch for "Hot spring for beauty".
Another way to describe it is that, although it is a weak alkaline hot spring, the coating effect of the "Chloride spring" prevents skin dryness, and the "Sulfate spring" also has a skin revitalizing effect, making it "A complete bath" from the standpoint of beauty. In other words, it can be called a hybrid "Hot spring for beauty" with multiple indications.

Tanigawa Onsen is located on the border between Gunma and Niigata prefectures, amidst a mountain stream and forest filled with negative ions, with a view of the famous Mt. Tanigawadake (altitude 1977m). Tanigawa Onsen is a relatively small hot spring area, but it seems to attract many travelers because of its one of a kind atmosphere and nature-rich environment. Tanigawa Onsen is said to have opened around 1400. There are records that literary figures and artists such as Osamu Dazai, Makisui Wakayama, and Yasunari Kawabata visited the area during the Taisho and early Showa eras. The "Bettei Senjuan" opened in 1997 as an annex of Ryokan Tanigawa on a vast site of 8,000 tsubo (about 6.5 Acres), which has now been expanded with the purchase of additional land to 20,000 tsubo (about 16 Acres). At the time, there were several inns in Japan offering guest rooms with open-air baths, but Senjuan may have been the first inn to offer open-air baths in every room. In 2012, the hotel was approved to join Relais & Chateaux, a prestigious hotel and restaurant group based in France. To become a member, a hotel or restaurant is subject to a strict "5C" assessment: Courtesy (heartfelt hospitality), Charm (refined and attractive space), Character (distinctive and individual style), Calm (calm and relaxing atmosphere), and Cuisine (high quality cuisine). Only a few hotels and lodging facilities in Japan have been approved to join Relais & Chateaux, and one of them is "Bettei Senjuan". The "Bettei Senjuan" has continued to thrive since its opening. This is probably due to the fact that the facilities are continually evolving and repeat customers keep coming back. A reading room was built in 1998, and dining rooms were added in 2000, 2006, and 2008. In 2004, an esthetic salon and footbath were opened. In 2008, a garden terrace with a hand bath was opened. The company is planning to hold events using the garden terrace and spacious courtyard to unite with nature, and we can look forward to its further evolution. The high level of not only the tangible aspect but also the intangible aspect of "hospitality" can be felt from many of the staff members. Under the leadership of Hidehiro Kubo, the president of the inn, the spirit to create a good facility can be felt. An inn that improves its intangible aspects in parallel with the tangible aspects of its facilities will also have a high level of customer satisfaction. The customers who frequent this facility may be more accurately described as supporters than repeaters. Spending time in a luxurious space in a quiet mountain setting is the happiest moment for a human being. It is a wise choice to spend a blissful time at the "Bettei Senjuan".
