Information updated 79 days ago
Itoshima Kaki begins on the Fukuoka coast facing the Genkai Sea. From autumn into winter, makaki oysters grow fuller in the shell and deepen in flavor, with rich milky sweetness and umami. Around October to April, oyster huts or sales points appear around Fukuyoshi, Fukae, Kafuri, Funakoshi, Kishi, and Nokita, giving the Itoshima shoreline a seasonal rhythm of hot shells, grill smoke, gloves, oyster knives, and port seafood.
