First, the definition and classification of hot springs

The hot spring law enacted in the twenty-third year of Showa, Japan made a clear explanation of hot springs.

Hot springs, that is, springs whose water temperature is above 25℃ when they gush from the ground or contain a certain amount of specific mineral components in 1 kg spring water (even if the temperature is below 25℃), are hot springs. There are low hot springs below 34℃, medium hot springs above 34℃ and below 42℃, and high hot springs above 42℃. In addition, hot springs are divided into 1 1 types according to pH value and osmotic pressure: simple hot springs, sodium bicarbonate springs, sodium salt springs, carbon dioxide springs, calcium-magnesium bicarbonate springs, sulfate springs, iron springs, hydrogen sulfide springs (sulfur springs), acid springs, radioactive energy springs (radium springs and radon springs) and aluminum-containing springs (aluminum springs).

Because mineral springs contain the most salt, the spring water with more than 65,438+0 grams of dissolved components in 65,438+0 kilograms of spring water is called salt spring, while the spring water with less than 65,438+0 grams (even if it contains multiple components) is called pure spring water. Among them, the types of hot springs (such as carbonate springs and sulfur springs) are subdivided again according to the most components contained in hot springs.

When 1 kg spring water contains one of the following seven special components: 1. Free carbon dioxide 1000 mg; 2. Copper ion 1 mg; 3. Iron ion 20 mg; 4. Aluminum ion 100 mg; 5. Hydrogen ion 1 mg; 6.2 mg of sulfur; 7. Oxygen11Beike is called a convalescent spring.

Second, the history of hot springs

There are detailed descriptions of the emperor's hot springs in ancient historical documents such as Ancient Records and Records of Japan in Japan, which shows that the Japanese learned to use hot springs long ago. In Nara era, due to the introduction of Buddhism, temples were built everywhere, and the bathing of monks played a great role in promoting the development of hot springs. At that time, people had discovered the therapeutic effect of hot springs. The records of Tangheyuan Hot Springs in Kanagawa Prefecture and Shenshantian Hot Springs in Nagano Prefecture in heian period's The Story of Ye Wan show that the hot springs in the east have also been developed. At that time, hot springs were mainly used for leisure, therapy and various religious activities of nobles and monks. At that time, hot springs had a deep connection with religion. After Yuanlai Dynasty established the Kamakura shogunate and moved the capital from Kyoto to Kamakura, hot springs in the East China Sea, Northeast China and Jiaxin began to appear in historical documents, and sick monks began to go to hot springs in various places for treatment. In the Muromachi era, hot springs became places of leisure and entertainment for dignitaries and others, and were not open to the general public. By the time of Antu Taoshan, hot springs had been widely used to treat wounded soldiers, especially in Jiazhou and Xinzhou, and the Warring States military commanders such as Takeda Shingen and Sanada Yukimura all had their own "secret soup". In the modern edo period, due to the underdeveloped medicine, the medical function of hot springs was paid attention to and thus developed to a great extent. During this period, not only generals and celebrities prevailed in hot spring treatment, but also the general public began to enjoy hot springs.

Third, Japanese hot spring tourism
