Since Japan is a volcanic island, there are hotsprings all over
the country from north to south. There are roughly 150 hotsprings
with 14000 individual springs. These natural treasures have been
used by many not only for medical treatment but also as a place
to communicate with others and relax. Many cultural elements have
sprong out just as the hot water from these springs. In recent years
there springs have become a part of modern medical rehabilitation
|The word hotspring is commonly used but
when asked "What is a
hotspring?" it is hard to give a definite answer. Where does all
that water come from anyway?........
Hotsprings are not only water lines
that are based on rain water being heated by earth's magma.
Many of the hotsprings are virgin
water springs (in some of areas when the earth's core is cooled
down and it releases gases and water vapor which turns into
hotwater) or fossil liquid (when ancient live forms died
at the begining
of time the remains disloved and turned into oil or water).
bill" signed in Syouwa 23rd year states: 1) Water temperature
needs to be higher than 25c. 2) The water must contain an prerequired
amount of minerals in 1kg of hotspring water. So if the water
meets both criterias then that water can be claimed as a hotspring.
There are many different kinds of hotsprings for different uses and different
||Water temperature is higher than 25c. Has
less than 1gram of radical carbon, salt and other mineral
elements. Good for neuralgia and rheumatism, also it is mild
making it perfect for long term rehabilitations.
||Has less than 1gram of radical carbon and other
mineral elements in each liter. Basically close to the Simple
Spring water but as you can guess from the name it is carbonated.
Many of them are low temperature and cold water springs.
Good for heart disease, blood circulation disorders, neurological
disorders, female disorders.
|Heavy Carbon Soil Springs
||More than 1gram/litter of radical carbon and
other mineral elements. Good for rheumatism, neuralgia, chronic
skin disorder. Also good for drinking to treat digestive
problems and inflammation of the bladder.
||Next to Simple springs in numbers, has more
than 1gram/liter of mineral elements. If the water contains
more than 1gram but less than 5gram of salt it is a weak
saltine spring if less than 10gram then it is a Salt Spring
, if more than 10gram the it is a Strong Salt Spring. Since
is highly sufficient in keeping temperature it is called "Atsu
no yu" (Warm hot water)
|Saltine Sodium Hydrogen Carbonate Spring
||Salt springs with Sodium hydrogen carbonate
content, alkine base.
||Good for arteriosclesis or cholecystitis and
rheumatism. Sulfite natrium base bitter spring. Not recomended
|Mirabilite Sodium Chloride Springs
||Mirablite springs with sodium chloride content.
Good for same usage as Salt Springs and Mirabilite springs.
||Good for rheumatism or wounds also help the
metabolism when drank. High in calcium content bitter spring.
|True Bitter Springs
||Sulfite magnasium is the main mineral content
, good for rheumatism. Low in numbers.
||Two different kinds of springs: Carbonate iron
springs and green vitrol springs. When the water is boiled
it turns red. The green vitrol springs contains sulfite iron
and strongly acidic vitrol.
||Indiginous to Japan. Mainly in volcanicly active
area, high concentration of hydrogen ions. Hard to bath in
and should be adviced before taking a bath.
||Main mineral element is sulfite alum. Good
for skin disorders. Mostly acidic alum or acidic alum green
||Contains Sulfhydryl ions or Sulfer hydrogen,
smells like rotting eggs. Good for drinking and treating
|| Contains a certain amount of radium or thoron,
good for digestive disorders or rheumatism.
|The Japanese always have been enjoying the hotsprings and much
abotu the springs is known as common knowlegde. You don't need to
be an expert to enjoy the springs but if you knwo a little more
you might enjoy the springs even more. Even if you already know
a lot just read it to brush up on your knowledge. (When you finish
reading the pointers, click on the hotspring "Onsen" icon , there
is an extra anecdote there....No , no AFTER you finish reading....)
||Just the hot springs are good for you doesn't means you should
stay in the spring for a long time. Try to keep it around 2,3
times a day 30min each including washing time. (10min physically
in the water , water temperature above 104F ) If the water temparuture
is below 104F then it is better to take long bathes. Luke warm
low mineral content water it is better to stay longer. If the
temperature is high then don't go straight into it, but warm
yourself up before you go in. It always is nice to do so anyway
for others in the bath so that they know you cleaned yourself.
||The hotsprings not only contain minerals but the water pressure
and buovancy is also good for stimulating the body. Just let
it go and try to just float in the water. This is believed to
relax you by simulating the environment inside a mother's womb.
Also by warming up , your pores open up and clear out, also
the minerals in the water will be absorbed.By bathing in the
hotsprings it not only relaxes you but it also balances your
||After bathing do you think "Well that was nice, I feel relaxed
now, time to go." Since it is a public bath you want to clean
yourself before you go? The minerals don't get absorbed by the
skin until 6-7 hours later. Therefore if you clean yourself
when leaving, you are washing the minerals away too. It is better
to clean youself with clean direct water at the spring or just
to leave it for a while.
||Not only are hot springs good for bathing but also for drinking.
The water contains minerals that will stimulate the metabolism.
Just because its good for the body doesn't mean drinking large
amounts is good. Make sure that the water is officially permitted
to be consumed, and then use the faucet that is designated for
drinking the water. Don't drink it in a gulp try to drink it
over 30-50 min period. Saltine, carbonate,sodium hydrogen carbonate
, radium are good to drink after a meal. You should drink hot
spring water on a empty stomach and not before spleeping.
|Out of all the hotsprings in Japan , we picked some out from the
northern part of Japan for this issue. Some of them are closelly
located but the folk tales and customs differ from spring to spring.
These springs have stories such as "so and so found this hotspring" or "this
historical figure has an interesting past" things that you don't
find in a regular history textbook. Offcourse these stories are
legends and folktales being past on generation from generation and
may not be very accurate but they are interesting to know. Well,
where would you like to start?
