Japan’s only crossbreeding of its kind — a rare, limited brand pork that Yamagata is proud to call its own.
Yamagata Keiyu Farm Kinkaton is an exceptionally rare — perhaps even a ‘phantom’ — brand pork produced at Keiyu Farm Co., Ltd., set beside the clear waters of the Midare River at the foot of the Ou Mountains in Higashine City, Yamagata Prefecture. It is the only farm in Japan to cross Berkshire female pigs with Jinhua male pigs. Jinhua Pig is an extraordinarily rare Chinese-origin breed, also called ‘the phantom pig,’ globally known as the raw material for the premium ingredient ‘Jinhua Ham.’ Yamagata Keiyu Farm Kinkaton contains no Landrace, Large Yorkshire, or Duroc blood whatsoever — and Keiyu Farm is the only farm in Japan producing pigs in this Berkshire × Jinhua crossbreeding style. Raised patiently over approximately 240 days — longer than standard — with a restricted ration of the finest quality feed, the sweetness and umami concentrate slowly and thoroughly into every fiber of the meat. The low fat melting point creates a melt-in-the-mouth sensation the instant the meat touches the palate, and the delicate, finely-grained muscle fibers are another major appeal. There is no lingering greasiness after eating — with every bite, an elegant umami and sweetness fills the mouth, and this is simply irresistible. Adopted as the ingredient at famous tonkatsu restaurant Katsukura, among other acclaim, it has earned high praise from discerning food experts. With annual shipments of just 650 head, distribution is extremely limited — and the very opportunity to taste it is precious. Please do try Yamagata Keiyu Farm Kinkaton — raised with love and care in the naturally rich environment beside the clear river, surrounded by cherry and apple orchards.
