Japanese hot springs are also called Onsen, which is quite famous around the world. There are more than 27,000 hot springs in Japan, and that is because of its plentiful volcanic activities throughout the country. Additionally, 47% of the Japanese hot springs have temperatures above 42 degrees Celsius. There are about 3,085 hot spring resorts in Japan that are provided with accommodation facilities. The majority of the Japanese hot spring resorts are distributed along volcanic belts, so there is no scarcity of heat sources for hot springs. The rainy season, typhoons, and snowfall play a vital role in bringing huge amounts of water resources to the Japanese archipelago. There is also an abundance of origins of hot spring water. These are some reasons that Japan is one of the world’s principal hot spring countries.
Onsen water is geothermally heated underneath the ground and rises to the surface bubbling hot. Because of this abundance of hot spring resources, the Japanese people have nurtured an authentic and special culture of bathing and healing in Japanese hot springs since ancient times. Scientifically it is proven that a therapeutic bath in hot springs can treat certain medical conditions and promote health benefits. The hot spring bath causes stimulation and penetration of various minerals and other elements that promote hormone secretion. It is also proven to prevent aging. It is said that 90 percent of diseases and aging are caused by free radicals. Free radicals are the oxidizing substances that cause corrosion to the cell membrane which further continues to damage the DNA and become cancerous. And since the hot spring water possesses restoration properties it is called the “waters of youth”.
Hot spring resorts in Japan
Kusatsu Onsen

This Japanese hot spring is located in Gunma Prefecture. It is situated at an altitude of 1200 meters above sea level. The water of this Japanese hot spring is sourced from Mount Kusatsu-Shirane which is located nearby. The sourced water is quite acidic with a pH of around 2, so an acid neutralization facility takes place to maintain the water quality that is suitable for fish to inhabit the rivers. The water at Kusatsu Onsen is comparatively much warmer than the rest of the Onsen listed here. And to cool it down a special stirring procedure (yumomi) is performed instead of adding cold water. It is because the addition of cold water would risk the potential of mineral contents in the water. This Japanese hot spring boasts an incredible forest view that plays a vital role in increasing one’s vibration. A bath in this Japanese hot tub is said to be able to prevent and cure any sickness except lovesickness.
