Kumamoto Oyster Crassostrea sikamea
Native range: Originally the Kumamoto region of southern Japan (now farmed on the U.S. West Coast)
Also known as: Kumo, Sikamea
The Kumamoto oyster, Crassostrea sikamea, originated in the Kumamoto region of southern Japan and has become a favorite on the U.S. West Coast since its introduction in the mid-twentieth century. Often called simply a Kumo, it is a small oyster with a deep, sculptural, almost bowl-shaped cupped shell that cradles a plump little morsel of meat. Once thought to be a variety of the Pacific oyster, it is now recognized as a distinct species. Kumamotos are prized for being exceptionally sweet, mild, and approachable, with low brininess, a firm yet creamy texture, and gentle fruity or melon-like notes that make them one of the most beginner-friendly oysters available. They grow slowly, which keeps them petite and concentrates their flavor. For people easing into raw oysters — or anyone who simply prefers a clean, sweet, non-briny bite — the Kumamoto is one of the most reliably crowd-pleasing oysters in the world.
