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.
