Kanehide Bio Co., Ltd.

Sulfated polysaccharide from Okinawa mozuku (Cladosiphon okamuranus). Highest fucoidan content among commercial seaweeds (up to 85-90% purity).

Three species of turmeric cultivated in Okinawa. Autumn turmeric is curcumin-rich, spring and purple varieties are essential oil-rich.

Fucoidan is a sulfated polysaccharide extracted from brown seaweeds, most commonly mozuku (Cladosiphon okamuranus) from Okinawa and kombu (Saccharina japonica) from Hokkaidō. Studied for moisturizing, immune-modulating, and antioxidant positioning. Sold as both a cosmetic ingredient and a functional food supplement.

Tropical vine cultivated in Ryukyu Islands for over 500 years. Central ingredient of goya chanpuru.

Okinawan variety of purple sweet potato with intense anthocyanin pigmentation. Heat-stable natural colorant.

Okinawa kokutō is traditional unrefined cane sugar produced by open-pan boiling of freshly pressed sugarcane juice, without centrifugation or refining. GI registration covers production on 8 specific islands. Each island produces a subtly distinct flavor profile attributed to cultivar, soil, and local production tradition.

Unripe papaya harvested before ripening, rich in papain, chymopapain, and carpain enzymes. Japanese fermentation techniques enable safe supplement use (raw papain is pharmaceutical-designated).

Edible green algae from Okinawan and Southeast Asian waters, characterised by its distinctive 'caviar of the sea' bubble texture from saline-filled vesicles. Okinawan production is concentrated in Onna, Itoman, and Kume Island. Live shipping in saline solution is standard for premium grades; freeze-dried and lightly-salted formats serve export markets. Marketed for export within Okinawa-longevity supplements positioning and as a luxury salad / sashimi garnish in upscale Asian and Western fine-dining.

Liquid bittern obtained as a by-product of seawater salt production. Primarily magnesium chloride (60–95%) with minor calcium and potassium. Indispensable as the coagulant for traditional Japanese tofu, and increasingly used as a magnesium-supply ingredient in hot-pot soups, beverages, and cosmetics. Domestic production is concentrated in Okinawa (Ishigaki, Miyako), the Seto Inland Sea (Ako, Kagawa), and Noto Peninsula. Mass-volume nigari for tofu manufacturing flows through cooperatives, while specialty single-origin nigari has emerged as a premium retail and wellness category.

Cosmetic-grade extract derived from awamori (Okinawan distilled spirit made from indica rice and black koji, Aspergillus awamori). Black koji's distinctive citric-acid metabolism and the long-aging tradition (kūsu, 3+ years) of awamori produce an active-ingredient profile with peptides, organic acids, and koji-specific metabolites distinct from sake-derived materials. Okinawan distilleries — concentrated in Naha, Ishigaki, and Miyako — produce both the awamori itself and the cosmetic-grade upcycled extracts.

Tropical superfood (Moringa oleifera) cultivated commercially in Okinawa since the 2000s. Sub-tropical Okinawan climate enables year-round harvest of leaves, with strong year-round productivity. Domestic cultivation supports a premium moringa supply chain distinct from large-volume Indian and Philippine sources, with certain Okinawan producers organic-certified and GMP-equivalent processed. Used in supplement powders, moringa-cha, plant-protein blends, and cosmetic anti-ageing actives. The Okinawan-origin label supports super-food retail positioning.
