What are natural carbonated springs?

What is special about Hida-osaka’s springs?

All natural springs at Hida-osaka are highly carbonated springs. These springs are also drinkable. Among them, YuyaOnsen is a long-established onsen (hot spring) with a history of about 400 years according to documents from the Edo period. Its water is drinkable and the onsen is well-known for its healing powers since its establishement. YuyaOnsen is a highly carbonated spring with a long history where locals have passed down Toji culture (hot spring therapy).


What benefits do carbonated springs at Hida-osaka offer?

Cure your stomach problems!

Carbonated springs at Hida-osaka have been considered as a stomach medicine since old times. They can help ease your constipation or enteropathy. The water may not be easy to drink due to its metallic taste, but you can use it for cooking. For example, when you cook tofu or rice with it, these ingredients will become softer and more delicious!

Enhance your skin!

Carbonated springs at Hida-osaka are slightly acidic. Among their ingredients are sodium bicarbonate, which has high-cleansing power for your skin, and ions such as sodium and magnesium to make your skin resilient, smooth, and soft.

“*These effects differ from person to person. If undesirable symptoms appear, please avoid bathing in or drinking the carbonated water.”
