YOI WATER Alkaline Water

ABOUTAbout the Brand

Founded in 2019, NAYAQUA Biotech follows a brand philosophy of "natural and healthy" and specializes in producing high-quality alkaline water. The name YOI comes from Japanese, meaning "the best, the finest." Its water is drawn from a natural golden source on Mt. Beidawu, which towers over the southern end of Taiwan's Five Great Mountains, and is rich in natural electrolytes and minerals. Because the source is naturally pure, with no additives and no chemical treatment, its pH stays stable and does not easily revert, keeping YOI WATER at pH 8.5 from bottling to opening. With a perfectly balanced natural mineral profile, YOI WATER offers a gentle, smooth, and pure taste.



The YOI WATER bottle design captures the natural poetry of Mt. Beidawu from dawn to starry night in three soft, matte tones: Mist Teal, Dusk Violet, and Star Blue.



YOI WATER is more than water; it is a daily ritual, a reminder to slow down and return to the balanced center of body and mind, letting every sip become a moment of conversation with yourself and adding a splash of color and good mood to every day.
