MTN WTR Expands U.S. Retail Footprint with Nationwide Launch at Daiso USA

MTN WTR, the naturally alkaline Japanese spring water brand sourced from the base of Mt. Fuji, announced today a new national retail partnership with Daiso USA. Beginning this month, MTN WTR’s Spring Water, Classic Sparkling, and EXTRA STRONG Sparkling varieties will be available in all 214 Daiso stores across the United States. The rollout marks a significant milestone for MTN WTR’s U.S. expansion, as it continues to build distribution with retailers aligned around premium quality, cultural relevance, and accessibility. Daiso, widely known for its broad assortment of affordable Japanese products, provides MTN WTR with a unique platform to reach consumers seeking authentic, high-quality beverages at scale.

“Daiso is an ideal partner for MTN WTR. Both brands share Japanese heritage and a mission to bring quality products to a wide audience. This nationwide rollout represents an important step in our strategy to build meaningful retail partnerships that combine cultural fit with accessibility,” said Masa Kinemuchi, CEO/Founder MTN WTR.

MTN WTR first launched in the U.S. market in 2022 and has since expanded across natural, specialty, and premium channels. With its EXTRA STRONG Sparkling format—a category-leading innovation inspired by Japan’s “strong” carbonation trend—the brand continues to bring new experiences to U.S. consumers while maintaining its core values of purity and design.
