The power of its highly acidic waters that is said to heal and rejuvenate
The term, “touji” or hot-spring cure refers to entering an onsen to cure any illness. At Tamagawa Onsen, people have come from all over Japan to find those benefits. It has the highest flow rate of water of any onsen at one place in the country, and soaking in its baths has the famous effect of a stinging sensation due to the high acidity of 1.2ph. Within the onsen, along with the bath fed by a source spring that has the highest stinging sensation of 100%, there is also a bath which has water diluted to a mild 50%, the Utase-yu Bath that has a massaging effect, the Ne-yu Bath where you can lie down in shallow waters and many other variations. There is no concrete basis for the baths being a cure-all, but it is believed that the effect of the elements in the onsen improves immunity and healing power.
From a day trip to long-term stays
There are many people who come for a long-term stay for the purposes of treatment and rest, and there are resorts where you can cook by yourself and ryokan-style accommodations with meals. You can even come to the onsen for a day trip so nearby there is the New Tamagawa Onsen which is popular with travelers who are looking for the amenities of a tourist hot spring.
