Kyushu Shoyu Soy Sauce Sweet Southern Style
Kyushu — sweetness influenced by historical sugar trade with Okinawa and southern China
Kyushu soy sauce (Kyushu shoyu) is characterized by pronounced sweetness from added sugar, amazake (sweet fermented rice drink), and high mirin content — a stark contrast to the saltier, drier soy sauces of Tokyo and Osaka. The sweetness developed historically from Kyushu's sugarcane cultivation and trade with southern China. Fukuoka, Kumamoto, Kagoshima, and Oita each produce regional variants ranging from moderately sweet to intensely sugar-sweet. Kyushu shoyu is used for sukiyaki-style preparations, grilled meats, and raw fish where its sweetness complements rather than competes. Nationally, Kikkoman and Yamasa represent standard saltier profiles; Kyushu brands like Yamami and Choko are sweeter.
