Nurtured in the snow country of Niigata — a premium pork with pure-white fat and rich umami.
Koshino Koganebuta is a Japanese brand pork (meigara-buta) from Niigata Prefecture, managed by Uoshoku Co., Ltd. Breed / crossbreeding: Three-breed cross (LWD): Female (Landrace × Large White) × Male Duroc.
The Murakami and Tainai area of northern Niigata Prefecture is a nature-rich region through which the Ara River — which won the top national water quality ranking in the Ministry of Land, Infrastructure, Transport and Tourism’s water quality survey for 3 consecutive years — flows. Koshino Koganebuta (Echigo Golden Pork) is Niigata Prefecture-produced brand pork which Uoshoku Co., Ltd. and contract farmers in this land have raised with devoted care.
The great appeal of Koshino Koganebuta is the beauty of its fat. The pure white, lustrous fat has a low melting point — smoothly melting in the mouth. A never-tiring, non-cloying finish — a gentle deliciousness once tasted and impossible to forget. The finely grained lean holds deep richness — the balance of fat and lean is exquisitely finished.
The commitment to feed is also not to be overlooked. A special feed tailored to the growth stage is given — centered on carefully selected corn, wheat, and brown rice. For the final 2 months, expander feed processed at high temperature and pressure is used 100% — further elevating meat quality and flavor. Furthermore, the Vitamin E and alpha-linolenic acid content is higher than standard pork — also outstanding in health aspects. The growing period is approximately 180 days, with the pigs raised slowly in a spacious environment without stress. The shipping weight is managed to approximately 110–115 kg — effort is also directed at quality stability.
Koshino Koganebuta is particularly suited to preparations that draw out the inherent umami of pork — such as tonkatsu, shabu-shabu, and ginger pork stir-fry. Also utilized in Niigata’s specialty ‘Tare Katsu Don’ (sauce-marinated katsu bowl) — the high quality is also backed by Hong Kong export achievements. Please do savor the flavor of this brand pork representing Niigata.
