"Beppu yunohana",precious hot spring essence
made by handfrom the Edo period.
The main ingredient of "HAA for bath" is yunohana, or mineral deposit from hot springs, which has been made in Beppu from nearly 350 years ago. These crystals only react to the blue clay found in the mountains of Beppu. By combining Beppu yunohana components with alkaline hot spring components in a delicate balance, we have achieved a bathwater quality rich in natural minerals, while being smooth and soft to the skin.
