Extracted straight from the northern Japanese Alps, enjoy a 100% all-natural hot spring mineral mix, producing authentic, light milky white water as if you are bathing at Okuhida Onsen. This Yunohana Onsen Powder is an all-natural mineral mix extracted straight from the mineral deposit on Mt. Yakedake in the northern Japanese Alps, with 159 Onsens in its vicinity. Mt. Yakedake is currently still an active volcano that is naturally producing highly concentrated mineral hot springs. Over millions of years, the naturally flowing mineral hot springs harden in the soil, and are then extracted and refined to produce the finest, most natural Onsen mineral powder. When you apply the Yunohana Onsen Powder in your bath at home, you get an unscented, light milky white, mineral-rich water that allows you to indulge in the atmosphere of actually being in an Onsen. As it warms your body up from the inside and out, it will also heal your body, and release tension and stress. This Yunohana Onsen Powder minerals have a low alkali base which saves your bathtub from sustaining damage, unlike other sulfur-concentrated Yunohanas. This package contains 250g of Yunohana Onsen Powder, equivalent to 10-15 uses.
