Onsen History

For a long time in Japan, bathing has been considered to cleanse the mind and body. It is a religion unique to Japan, a Shinto shrine. When important ceremonies were held in the court, the public were taught to get up early in the morning, bathe in water, cleanse their minds and bodies, and then go out.
It is the habit of going down to the common people. The act of refreshing while sweating with the water of a tub reflects the Japanese people's desire to clean up the mind at the same time.
In the middle of the 8th century, the continent came with a large number of Buddhist scriptures, called the "greenhouse sutra".
This is the teaching that "when you take a bath, you get merit". Originally during the Misogi ceremony, the mind and body were cleaned with cold rivers, waterfalls, and sea water, but the hot water and hot springs that were boiled were much more comfortable physically.
It is not hard to imagine that the scripture saying, "If you look at the bath, you can get merit. You can get rid of seven diseases and get seven fortunes.
The fusion of Shinto's “Misogigi” spirit and Buddhism's “Greenhouse” may have resulted in a ethnic group who loves baths, hot springs, and cleanliness.
This is not a culture of simply washing away the dirt on the body's surface in Europe and the United States with a shower, but a Japanese culture of immersion that cleans even the dirt of the heart, a hot spring culture.

Hot Spring Effectiveness

Hot spring was the origin of spa therapy.
There is a word in the hot springs used to heal diseases and improve health in hot springs. This is the basic unit and period of hot water treatment established 400 to 500 years ago before the Edo period.

The effect of a hot spring is basically “stimulation”. Various components penetrate the human body and promote the secretion of hormones. At the beginning of the treatment, the sympathetic nervous system predominates blood pressure rises, heart rate increases and blood sugar level rise.

The parasympathetic nerve then becomes dominant to correct this condition, lowering blood pressure, lowering heart rate and lowering blood sugar. In this way, the sympathetic dominant phase and the parasympathetic dominant phase are alternately expressed, and eventually the body goes into a stable equilibrium state and the body recovers.

If you stay at the spa for one week, you can almost achieve this effect. In the past, people knew this not through science, but through empirical rules and lore.

Money for digging out Onsen source


By the way, it is an interesting price, but it is said that the cost of the survey is at least 10 million yen for 100 meters, so it costs 100 million yen to dig 1,000 meters out. Of course, this is just digging, so it does not include the pump for pumping the hot spring or the cost of obtaining a permit.


In this way, enormous amounts of money and labor are required for hot springs.
The hot springs are built by indescribable efforts. When you go on a trip, it may have a different taste when you try to enter the hot spring while thinking about the courage and heart of the people who dug the hot spring at that place.


Carbon dioxide Onsen (Hot Springs)


A popular carbonated spring because it has bubbles on your body. In recent years, artificial carbonated springs have come to be seen in super sento, but there are few people who have taken a bath in natural carbonated springs. Carbonated springs are extremely rare and are only available in Japan.
We will introduce the power of carbonated springs, which have a wide range of effects on beauty and health, and the rare hot springs that can be used in carbonated springs in Japan.
The carbonated spring is called "carbon dioxide spring" in the correct spring quality name. Literally, this is a hot spring in which carbon dioxide (carbon dioxide) is dissolved, and it contains more than 1000 mg of carbon dioxide per kg of hot water. The biggest feature of carbonated spring is the bubbles that adhere to your body when you take a bath.
This carbon dioxide gas bubble is absorbed into the body through the skin, expanding blood vessels and smoothing blood flow.
It lowers blood pressure and reduces the burden on the heart, so it is also known as high blood pressure and heart disease. In addition, improved blood flow promotes metabolism and facilitates the discharge of waste products, which is also a nice rejuvenating effect for women. In addition, rheumatism, coldness, and drinking springs are good for diabetes, gout, and gastrointestinal diseases.
