'Deep-sea water' (DSW) is seawater drawn from several hundred metres depth, below the photic zone, where it is naturally cold, low in bacteria/pathogens and rich in dissolved minerals (magnesium, calcium, trace elements) compared to surface seawater; it is pumped up, desalinated/mineral-adjusted and marketed as drinking water, mineral concentrate, and a cosmetic/food ingredient.
Kumejima Island in Okinawa Prefecture hosts one of Japan's earliest and best-known deep-sea water intake facilities (established in the early 2000s), drawing water from roughly 600m depth off the island; the facility supports a genuine, government-supported regional industry cluster covering bottled water, mineral-salt products, food and cosmetic ingredient supply, and even deep-sea-water-cooled agriculture and aquaculture research.
Okinawa Deep Sea Water is an established Japanese commercial category with both domestic retail presence and export to health/wellness and premium cosmetics markets in East Asia and beyond; buyers include bottled-water brands, mineral-supplement formulators and cosmetics manufacturers seeking a marine-mineral ingredient with genuine, verifiable single-source provenance.
No CITES or wildlife issue applies. Water/mineral products are regulated under Japanese food-safety law for drinking-water and food-ingredient use, and Kumejima's facility operates under Okinawa prefectural and national oversight; export requires standard Japanese food-safety export certification and, for cosmetic-ingredient use, compliance with the destination market's cosmetic-ingredient safety rules (EU/US).
