Yukimuro Jukusei Koganebuta

Sheltered and blessed by the snows of Niigata — please savor the top-quality tenderness and deep umami born of snow-aging.

Yukimuro Jukusei 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.

This is fine-quality pork made by slowly maturing a brand pork using ‘Yukimuro’ (snow cellar) — a traditional preservation technique cultivated by the snow country culture of Niigata. A yukimuro is a natural storehouse utilizing large quantities of snow. The interior maintains a stable environment of around 1–2°C year-round with humidity of 90% or more — these conditions of low temperature, high humidity, and low oxygen slowly work the enzymes, deepening the umami and tenderness of the meat.

Yukimuro Jukusei Koganebuta (Snow-Cellar Aged Golden Pork) is an upper-grade brand in which the Koshino Koganebuta raised in the Murakami and Tainai area of Niigata Prefecture has been slowly snow-aged in this yukimuro. Koshino Koganebuta is a three-breed cross — Landrace × Large White female crossed with Duroc — carefully fed a special feed centered on carefully selected corn, wheat, and brown rice tailored to each growth stage. The shipping age is 180 days — by setting this slightly longer than standard, the meat’s umami is abundantly accumulated.

Pork that has undergone yukimuro aging has a lower fat melting point — a softness that gently settles in the mouth when eaten is born. With the increase of umami amino acids, the sweetness and mellowness stand out — never tiring no matter how many times it is eaten, a flavor of great depth. Enjoy the ingredient’s flavor fully in simple preparations such as steak and salt-koji grilling — it is also widely applicable to shabu-shabu, ginger pork stir-fry, and stir-fry dishes.

Managed by Uoshoku Co., Ltd. (Chuo Ward, Niigata City) — annual shipments approximately 3,000 head, a rare specialty. Proactively pursuing exports overseas as well — growing name recognition both domestically and internationally as a premium pork representing Niigata.
