Kokuto (黒糖) is the unrefined dark sugar produced from Okinawa-cultivated sugar cane. Unlike highly refined white sugar, kokuto retains the molasses fraction, giving it a distinctive deep flavor and substantial mineral content (calcium, iron, magnesium). Several specific Okinawan island kokuto productions are protected under Japan's GI system; cosmetic and ingredient labels use the generic term.

FAQ for OEM buyers
Q. What is Okinawa kokutō and how is it different from regular brown sugar?
Kokutō (黒糖) is unrefined whole-cane sugar produced by simply boiling and concentrating the freshly pressed juice of sugarcane until it solidifies, with no centrifugation or molasses removal. Most globally traded 'brown sugar' is actually refined white sugar with molasses added back; kokutō is a single-step traditional product in which the molasses fraction is never separated, giving it a deeper color, a richer mineral profile, and a distinctive flavor that differs noticeably from refined sugars.

Q. Is 'Okinawa Kokutō' a Geographical Indication?
Yes. 'Okinawa Kokutō (沖縄黒糖)' was registered under Japan's Geographical Indication (GI) Protection System administered by MAFF (registration number 25, registered December 2018). The GI covers kokutō produced on eight specific Okinawan islands: Iheya, Izena, Aguni, Kohama, Hateruma, Kuro, Tarama, and Yonaguni. Production must follow defined traditional methods using sugarcane grown on those islands.

Q. What is the mineral content of kokutō?
Kokutō retains the mineral content of the cane juice. Per the Standard Tables of Food Composition in Japan, kokutō contains approximately 240 mg/100 g calcium, 31 mg/100 g magnesium, and 1100 mg/100 g potassium — substantially higher than refined sugar (white sugar contains essentially zero of these minerals). It also contains small amounts of iron and B-group vitamins.
Q. Does each of the eight GI islands really produce a different kokutō?
Each of the eight GI-registered islands operates its own kokutō factory with its own sugarcane fields, harvest timing, boiling pan style, and crystallization technique, and the published GI specification recognizes these flavor differences. Side-by-side tasting reveals discernible differences in color, hardness, and flavor (notes range from caramel-forward to mineral-savory). Premium retail and pâtisserie lines often source from single-island producers and label accordingly.
