What Premium Water does

Premium Water Holdings, Inc. (株式会社プレミアムウォーターホールディングス, TSE Standard Market: 2588) is the publicly traded parent company of Japan's largest home delivery natural mineral water subscription business, operating under the flagship PREMIUM WATER brand and the Locca water purifier server rental brand. Founded in 2006 in Fujiyoshida City, Yamanashi Prefecture, and controlled by Hikari Tsushin, Inc. since 2015 via a tender offer, the company serves more than 1 million subscriber households (as of March 2020) through direct-to-consumer subscription plans plus add-on services such as the PREMIUM MALL e-commerce site for subscribers. The holding company structure (adopted in 2016) encompasses operating subsidiaries including Premium Water Co., Ltd. (home delivery), Premium Water Products Co., Ltd. (manufacturing), Water Offgrid Co., Ltd. (off-grid water solutions), Singapore FLC Pte. Ltd., and Premium-Plus Co., Ltd.

The company's core product is unheated natural mineral water bottled in 12L containers, sourced from four Japanese production sites (Fujiyoshida, Nishikatsura, Asago, Gifu Kitakata) and delivered to subscribers on a recurring schedule. Water is selected under six proprietary criteria and subjected to 10+ daily microbiological, physicochemical, sensory, and periodic radiation tests; the company highlights that all sources produce soft water suitable for infant formula. The Locca brand extends the platform with a tap-water purifier server rental for customers preferring filtered municipal water. Supporting infrastructure includes a Kawaguchiko logistics center, an Osaka joint-delivery partnership with Kokuyo Supply Logistics (reducing ~2,000 delivery vehicles annually), and a Physical Internet relay transport partnership with ITOCHU.

Revenue is generated primarily through recurring monthly subscription fees on the home delivery contract base, supplemented by water server rental payments, Premium Mall e-commerce transactions, and ancillary services. The primary customer segment is Japanese individual households (B2C), with a secondary institutional use case in welfare facilities and disaster relief support. The company also pursues ESG/SDG initiatives (931 tons annual plastic reduction since 2015, 52% CO2e reduction vs. equivalent PET bottles per Deca-Bos certification) and is regulated by ISO 9001 (since 2011) and Privacy Mark (since 2022), with a BBB+ credit rating from R&I assigned in November 2025.
