Definition of hot springs according to the hot spring method

in Japan,1948/(23) Onsen Law was enacted on July 7. According to Article 10 (Definition) of this Hot Spring Act, a hot spring is defined as "hot water, mineral water, steam, and other gases (natural gas containing hydrocarbons as the main component) that emanates from the ground that satisfies one or more of the following: Is defined as (excluding hot springs in a broad sense by legal definition).

Classification according to the spa analysis method guidelines

The mineral spring analysis method guideline established by the Ministry of the Environment distinguishes between "normal water" and "mineral water." If the temperature at the time of seepage is 25 degrees Celsius or higher, or if the specified component is higher than a certain value, this is classified as "mineral water" ("Spa"and"Spring qualitySee also).

Izumi temperature
It is classified into the following four types depending on the temperature at the time of seeping or sampling.
  1. Cold spring-less than 25 degrees Celsius
  2. Micro Onsen-Izumi 25 degrees Celsius or more and less than 34 degrees Celsius

Therapeutic spring

The Spa Analysis Method Guideline specifically identifies those that can be used for therapeutic purposes.Therapeutic springAnd further stipulates the eight substances identified.

If the temperature of the spring source is 25 degrees Celsius or higher, or if 1 kg of the hot spring contains one of the following components in excess of the specified amount, you can claim the therapeutic spring in the guidelines for the analysis of mineral springs.

  • Total dissolved substances (excluding gas)-1000mg
  • Free carbon dioxide-1000 mg
  • Cu2+ -1 mg
  • Total iron ion (Fe2++ Fe3+)-20mg
  • Al3+ -100 mg
  • H+ -1 mg
  • Total sulfur ([HS-,S2O3--,H2Corresponding to S)-2 mg
  • Rn-111Bq

Furthermore, therapeutic springs are classified as follows according to the components and amount of dissolved substances.

  1. Salt spring-Dissolved substance amount (excluding gaseous substances) 1g/kg or more
  2. Simple hot spring-Amount of dissolved substances (excluding gaseous substances) less than 1g/kg and hot water temperature of 25 degrees Celsius or more
  3. Rejuvenation springs containing special ingredients-those containing special ingredients above a certain value


Types of hot springs

Therapeutic spring

Medical treatment springs are classified according to the components they contain. In addition, there are three types of names, such as the name of the spring for notice, the name of the old spring, and the name of the new spring.

Hot springs that are not therapeutic springs

Although there are hot springs defined by the Hot Spring Law, some hot springs (mineral springs) do not fit into the above 11 categories. Specifically, the spouting temperature is less than 25°C, the content component contains 1000 mg/kg or more, or the metasilicic acid, metaboric acid, etc., contains more than the specified amount, but the specified component of the therapeutic spring contains more than the specified amount. There is no hot spring. The quality of these springs cannot be classified, and for convenience, they are commonly referred to as "Hot springs on the hot spring", "Fluorine-containing springs", "Metaboric acid springs", "Metasilicic acid springs", "Simple springs", "Cold mineral springs" Named according to characteristics. Formal indications cannot be posted, but if you want to warm and batheGeneral indicationThe same effect as can be expected.

Hot springs in the world

The usage patterns of hot springs are roughly divided globally,Take a bath and rest(This is the mainstream in Japan),Take a bath and recuperate,Take a bath and enjoy(Swim, etc.), andto drink(Drinking spring),Use steam(sauna,Steam bath).Bathing and resting is a unique Japanese culture that reflects the humid climate (exceptionally, Japanese bathing is widespread in parts of Asia), and is enjoyed, recuperated, or drunk worldwide. It is recognized as a thing, a thing to steam.However, due to today's boom in Japanese culture and the penetration of onsen culture (described later), Japanese-style bathing is spreading all over the world.

Historically, hot springs were in the 3000s and 4000s BCEgyptIs used inEtruscanAlso built a hot spring facility around the source and had a system for investigating and managing the mineral springs.Ancient greeceIn the times, the use of hot springs for the treatment of illnesses had already been established, and the mysterious power of hot springs was linked to faith,pilgrimageAnd developed as a place of treatment.Ancient romeDuring the era, the construction of recreational facilities connecting hotels and hot springs was further promoted, and it was constructed in a wide range from luxurious resort facilities for the affluent to ordinary people. Amusement facilities appeared in the hot spring town and flourished as a place of entertainment and entertainment.Roman EmpireBecame lonely with the decline of.キ リ ス ト 教In the early days, in order to eradicate the Roman belief in hot springs, the hot spring facilities were demolished, and instead churches and other Christian facilities were constructed. In the 13th centuryCrusaderThe medical use of hot springs started again from the information on the baths in the east reported by, and in the 15th century, the hot springs returned to activity due to the community's efforts to manage hot springs. In the latter half of the 19th century, hot spring resort heat revived and became a hot spring town.casino,VillaHas been actively built, and it has reached the present[12].


As a hot spring resort in Europe,Karlovy Vary, Britishバ ー ス,BelgianSPA, HungarianBudapest,Germany'sBaden-BadenAre famous. For details, refer to the item below.

Whereas Japanese hot springs have evolved for bathing, especially in modern Europe, "drinking hot springs"Drinking fountainIs deeply rooted in the hot spring culture.Karls Hot SpringsThe origin of the famousCarlsbadIs a hot spring resort for drinking springs.

Until the 15th century, bathing was the main activity,Volcanic beltThe hot spring area did not develop because the amount of hot water was small and the hot spring temperature was low. In addition, the disorder of the disciplinesyphilis,PlagueSuch asEpidemicBathing was considered to be harmful to the body due to the prevalence and social background due to religious reasons, and the practice of bathing was shunned (see "bathingSection). On the other hand, in Europe, the quality of drinking water was poor, so that some bathers were drinking hot spring water. The hot spring resort with this in mind was bottled and put on the market, and it received a great reputation. famousEvian,VichyIs also hot spring water. In Japan as well,Wilkinson""Ginger ale, Etc.soda drinkWas initially made from carbonated spring water.

In addition, since the medical effect was clear by directly drinking the hot spring water, the drinking spring and medicine were immediately linked. This is because hot springs in Japan hindered the influx of Western medicine and for a whileSpa therapy Folk remediesThis is in symmetry with the delay in research due to the fact that there was a large injured facility of the Army and Navy.BeppuAndMisasaSome hot springs were established and connected with neighboring universities, and research was conducted steadily).

Today known as a hot spring townバ ー ス,KarlsbertIsResort areaIt will also develop and will be equipped with hot spring hospitals and retirement facilities. It is the same as Japan in terms of recreation by hot springs. There are also hotels and restaurants built, but there are no hot springs for bathing (Europe, especially Western Europe and Eastern Europe, are not as wet as Japan, which is a major reason why the bathing culture did not develop). Fountains and fountainsbarIs provided.
