Water quality

Gero Onsen has the quality of an alkaline simple onsen. The color of the water is colorless and transparent, and the alkaline simple onsen, which has a smooth feel, is characterized by the fact that the skin becomes smooth after bathing. Bathing in an onsen with this quality removes dead skin cells, so it is called "beautiful skin water".

The main indications are neuralgia, muscle pain, joint pain, frozen shoulder, motor paralysis, joint stiffness, bruises, sprains, hemorrhoids, chronic digestive diseases, sensitivity to cold, recovery from fatigue, and health promotion.

In addition, it is also called "health bath" because it is good for health promotion such as fatigue recovery and stress relief. The hot water of Gero Onsen has a Ph value of 9 or higher, has a moderate skin-beautifying effect, and is characterized by the fact that the water does not cool down easily even after bathing.

Gero Onsen, one of the three most famous onsens in Japan, is an onsen resort with a very long history of more than 1,000 years. The origin of Gero Onsen is said to be in the middle of the Heian period, and legend has it that it was discovered in 947-957 AD on the mountain "Yugamine", a little away from the current onsen town.

However, the onsens that had been gushing out near the top of Yugamine suddenly ceased to appear in the middle of the Kamakura period, in 1265 AD. The rediscovery of Gero Onsen was near the Hida River, where the current onsen town is located.

The rediscovery of Gero Onsen has been passed down as the "Legend of the White Egret", and it is said that an egret swooped down in front of the villagers who were having trouble finding an onsen and announced the new onsen.

Gero Onsen has grown in popularity since it moved from the top of Yugamine to its current location, and has continued to develop while overcoming difficulties such as disasters.

In addition, the person who introduced the existence of the famous Gero Onsen to the world was a monk of the Muromachi period named "Manri Shuku". At the "onsen Thanksgiving Festival" held every year, the achievements of Wanli Shuku, which has a deep connection with Gero Onsen, are honored.

In modern Gero Onsen, "frogs" have become established as characters in the onsen town, and you can enjoy frog-related things in various parts of the onsen town. The frog is perceived differently depending on the country and religion, but it is a creature with various symbols such as the god of rain, fortune, and prosperity of offspring.

In Japan, it is considered a lucky charm that brings good luck, and the frog's "Gerogero" cry and Gero Onsen are sprinkled on it. In the onsen town, you can enjoy frog shrines and Gero pudding, and there are frog objects in various places, so it is recommended to take a walk.

Gero Onsen is an onsen resort with a very fascinating history, from ancient times to the present day.
