How to use onsen
【Direct Effects】～Onsen themselves are effective～
Various elements such as carbon dioxide gas, common salt, sodium bicarbonate, iron, sulphur and radon (radioactive) are present in onsen depending on the region or source. It is possible to divide hot spring water that has therapeutic effects into 9 types depending on their principal elements and it has been medically proven that these each have effects on various symptoms. Some effects can be obtained not only by bathing in hot spring water but also by drinking it. In addition, there are some onsen resorts such as Tamagawa Onsen and Murasugi Onsen where not only water but also radon, etc. that is emitted in the area has a good effect on the body.
【Indirect Effects】～A change of scenery～
Spending time in a place that is different from your normal environment or looking at the beautiful Japanese scenery provides a release from everyday life and relieves stress. Onsen are the ultimate weapon in the quest for relaxation. They work directly on the body while clearing and cleansing the mind.
Frankly, you should aim for weekdays. As there are many ryokan that still raise their prices from the eve of holidays, weekday users can have the same services for a more reasonable price. Furthermore, as onsen are rarely crowded at these times, rotenburo (open-air bath) and large baths can be used at your own pace. It is also much easier to interact with the people running the traditional Japanese inn as they will have more time than on busy days.
