英語版-湯躍とは

YUYAKU is a medicated bath powder created from Onsen (meaning hot spring) minerals "Yunohana" that was developed after consideration and research for over 50 years based on Japanese traditional balneotherapy, toji, passed down from ancient times in Japan.

In Japan, a country of volcanos, hot springs have been a familiar existence inseparable from the activities of humans.
There is a word, toji, in Japanese.
It means to cure illnesses or injuries by bathing in a hot spring.
Toji ingrained a unique Japanese bathing style where the person submerges themselves in water hotter than 40℃.
The custom of bathing daily is thought to be one of the reasons Japan has the highest longevity in the world.
YUYAKU was developed as a new toji custom that takes root in daily life from the long continued research into the power of hot springs.

Unique to the hot springs in Beppu, Japan's largest hot spring resort area, is the growing of hot spring water flowers, which has been done for over 350 years. This traditional method is just like growing hot spring “flowers.” "Yunohana” are natural mineral crystals in which are concentrated the hot spring ingredients. The Yunohana extract is full of minerals important for beauty and health. The hot spring minerals gently envelop the body.

The ingredients are naturally and slowly extracted from Yunohana without leaving any behind and then are refined into Yunohana extract. During this process, the sulfur that damages bathtubs and smells badly is removed. The extract is further combined with alkaline hot spring water, which has characteristics that gently make the skin smoother, to finish this medicinal bath powder that can be used daily at home.
