Yuyaku Onsen Bath Salts Cylinder Gift Set is a Japanese onsen-style bath additive set created using natural hot spring mineral components and traditional extraction methods.

This gift box includes three different bath salt types, each presented in a cylindrical format and inspired by different bathing textures and colors: clear water, cloudy white water, and lightly colored translucent water.
The bath salts are weakly alkaline and dissolve smoothly in warm water, creating a gentle and balanced bathing experience.

A key feature of Yuyaku bath salts is the use of purified onsen mineral extract collected from traditional yunohana huts, which have been preserved as an Important Intangible Folk Cultural Property in Japan since the Edo period.
Instead of simply blending synthetic mineral formulas, Yuyaku products are produced using an aging process focused on natural raw materials, allowing trace elements found in real hot springs to remain in the final bath additive.

This product is classified in Japan as a quasi-drug bath additive and is suitable for daily bathing.
The set is presented in a gift box and is suitable for seasonal gifts, family use, and special occasions.
