The onsen review is rather interesting for many people including foreign tourists constantly coming to Japan. Japanese onsens have been for a long time used not only for relaxation and joy, but also for various medical purposes, for improving the humans' health and entire human body's condition. Nowadays, Japanese onsens have become a part of recuperation and medical rehabilitation as well as an integral part of the country's cultural traditions, which go back in the past for many centuries.
Speaking about the onsen review, it's important to pay attention to the fact that not all the Japanese hot springs are natural. As a matter of fact really natural hot springs are known to come from the volcano that's why water is supposed to have strong sulfur smell. And only natural Japanese hot springs are called onsens. Besides them there are lots of Japanese hot springs which are not formed by the natural source. They are heated artificially and called sentou. Such kinds of Japanese hot springs can only be a relaxing option with no medical affect on the human's health.
One of the significant facts of our onsen review to be taken into consideration is that Japanese hot springs are referred to as not only the water lines based on rain water heated by the earth's magma. Today many of the hot sprigs still remain virgin. In some areas where the earth's core is cooled down and releases some gases as well as water vapor which later turns into hot water. It goes without saying that every onsen should meet particular requirements regarding temperature and minerals contained in the water.
According to the basic facts of our onsen review the temperature needs to be higher than 25 degrees and water is supposed to contain pre-required amount of minerals per 1 kilo of hot-spring water. Thus, if the water meets the both mentioned criteria it can be called a hot spring. It's interesting that under the Japanese Hot Spring Law (1948) the government recognizes the onsen as one of the hot springs, which meet certain standards concerning the mineral composition and temperature. In 1990 the list of onsens of such kind reached about two thousand and thirty. However, still many experts believe that there are only 64 Japanese hot springs which are capable of providing real medical treatment and contribute to the people's health improvement.
According to our Japanese onsen review, there are many different onsen types which have different distinguishing features and therefore - are used for different purposes. Onsens may have various forms and range from open-air pools to simple tubs in special rustic huts. There can also be enormous onsen complexes with a great number of baths, saunas, waterfalls and steam rooms. Some Japanese onsens are located within the public bath houses. Other ones are the part of the hotel or inn where the person can often pay a certain fee just for using a bath.
So, we hope our Japanese onsen review has provided you with the basic facts regarding Japanese hot springs and their peculiarities.
