Aqua Clara Japan

What Aqua Clara Japan does

Aqua Clara Japan (Aqua Clara, inc.) is a privately held Japanese subscription-water-delivery company founded in 2005 and headquartered in Minato, Japan, with 101-250 employees. The company delivers reverse-osmosis (RO) purified water at a hardness of 29.7mg/L to households and offices across all 47 Japanese prefectures through a direct-to-consumer website and toll-free call center combined with a nationwide franchise/dealer network. Its core product is a portfolio of seven water-server models (Aqua 8, Aqua Fab, Aqua Slim, Aqua Slim S, Aqua With, Disney/Pixar Design Server, and Herarubony Design Server), each paired with reusable 12L or 7L RO-water bottles delivered on a recurring basis.

The underlying technology centers on a proprietary RO-membrane filtration system that removes impurities down to 0.0001mm, with purified water subsequently blended with four minerals (calcium, sodium, potassium, magnesium) to achieve a softness profile tuned for Japanese cuisine and taste. Safety and hygiene are reinforced through the O2CleanR\u00ae antibacterial cleaning system co-developed with Lion Corporation, UV sterilization in cold-water tanks, SIAA-certified antimicrobial components, JDSA child-scald-prevention certification, and standard child-lock faucets. The company has received the Monde Selection Grand Gold Quality Award for 14 consecutive years and a 93% physician recommendation rate from an AskDoctors survey of 100 internists (May 2026).

Aqua Clara generates revenue primarily through recurring monthly 'Anshin Support' fees (¥1,100-2,200 per month depending on server model) bundled with per-bottle water charges, with customers entering default 2-year auto-renewal subscription contracts. Average monthly billing for a standard household runs ¥3,740-4,840 (approximately ¥130/day). Supplementary revenue streams include a Kosodate child-rearing discount plan (¥550/month), bundled services such as Aqua Hikari fiber internet and the Aqua Clara Epos co-branded credit card, the Aqua With coffee-machine integration with Nestlé Nescafe delivery, and credit-card partner storefronts with ANA and JAL.
