Kobe Beef — The Tajima Standard (神戸牛)

Hyogo Prefecture, Japan — specifically the Tajima region (northern Hyogo). Tajima cattle were first documented in Japan's oldest history (Nihon Shoki, 720 CE) as agricultural working cattle. Beef eating began in the Meiji period (1868); the Kobe beef designation was formally established in 1983.

Kobe beef is the most famous brand of Wagyu — specifically Tajima-gyu cattle (但馬牛, a sub-breed of Kuroge Wagyu) raised in Hyogo Prefecture under strict protocols and meeting BMS 6+ and yield grade A4 or A5 standards. The Kobe Beef Marketing and Distribution Promotion Association rigorously controls the designation — only cattle raised in Hyogo, slaughtered at designated facilities, and graded to specific standards can be called Kobe. An estimated 3,000–4,000 cattle qualify annually for Kobe designation — making genuine Kobe one of the world's most genuinely rare beef designations. Most 'Kobe-style' beef sold internationally is not genuine Kobe.

Genuine Kobe beef at BMS 8–12 delivers the fullest expression of Wagyu's fat-sweetness: the oleic acid's low melting point produces immediate, clean richness on the palate. The specific Hyogo feed protocol — including local rice straw — contributes a subtle complexity to the fat character that breeders and graders can identify in blind tasting. The lean meat's iron character provides necessary contrast. Over thin slices on teppan, the fat renders instantly, creating a pool of clarified Wagyu fat in which the remaining slices are briefly basted — a self-generating sauce.
