What プレミアムウォーター（株） does
プレミアムウォーター（株） (Premium Water Co., Ltd.) is a privately held Japanese home water server subscription company headquartered in Shibuya, Tokyo, and operating nationwide (excluding Okinawa and remote islands). The company sources non-heated (raw) natural mineral water from three owned spring locations — Fujiyoshida, Gifu Kitagata, and Minami Aso — and delivers it to households in 12-liter one-way disposable bottles on weekly to monthly cadences. Its product lineup includes five server models: AURA (a nendo-collaboration premium model, 2024 Good Design Award winner), famfit2 (family-oriented bottle-bottom-loading), Slim Server 4 (long/short form factors), and the amadana Standard and Grande co-branded servers. Servers integrate temperature-controlled tanks (cold/warm/hot/room temperature), eco-mode light sensors (~20% energy reduction), child-lock safety features, and gravity-fed manual lever emergency faucets that operate without electricity.
The business model is a recurring subscription revenue stream, with the flagship Motto PREMIUM plan priced at ¥4,082/month (12L x 2 bottles, free shipping, free server rental, 5-year minimum contract). Tiered offerings include the MOM CLUB plan at ¥3,866/month for households with pregnant women or preschool children, and PREMIUM WATER FUTURE at ¥4,536/set (12L x 2 bottles) targeting SDGs-conscious consumers with 2% of sales donated to WaterAid Japan and EXILE group ambassadors (TETSUYA, NAOTO, Shirahama Aran, Sato Daiki). Complementary revenue streams include the PREMIUM MALL e-commerce platform (subscriber-exclusive accessories, groceries, beauty, household goods) and unit-priced add-ons such as the self-cleaning kit (¥2,750) and emergency kit (¥3,542).
The company acquires customers primarily through direct-to-consumer channels: the official website premium-water.net (with web-limited campaign promotions, AR try-before-you-buy, and SEO-optimized content marketing), a phone campaign desk (0120-062-032), and event sponsorships (Animelo Summer Live 2026, SEKIGAHARA IDOL WARS 2026). Existing customers are managed through a smartphone app and my-page. The company claims No.1 water server market share in Japan (Nihon Ryutsu Sangyo Shimbunsha, December 2025), No.1 customer satisfaction (MyVoice.com, July 2022), and PFAS non-detection across all water sources, supported by publicly disclosed safety testing.

Revenue model
- Water bottle subscription and delivery (宅配水サービス): Core recurring revenue stream from monthly/periodic delivery of natural mineral water in 12L one-way bottles. Customers select delivery frequency (weekly to monthly) and are locked into minimum contract periods (5 years for most plans). Water subscription is bundled with free or low-cost server rental. This is the dominant revenue driver.
- PREMIUM MALL accessory and grocery e-commerce: A subscriber-exclusive online marketplace (mall.premium-water.net) selling water server accessories (self-cleaning kits, tower kits, emergency kits), household goods, groceries (wagyu beef, seasonal produce, seafood), beauty products, and appliances. Revenue is transaction-based on individual purchases, complementing the core water subscription relationship.
