Raised in Ibaraki — a brand pork of overflowing umami, brought out by a root vegetable-enriched feed.
Ajiwai Pork, produced by Osato Livestock in Namegata City, Ibaraki Prefecture, is a brand pork that realizes consistent quality through unified sourcing of parent pigs and thorough feed management. The defining feature is the incorporation of root vegetables into the feed. The umami components derived from root vegetables draw out the deep, authentic flavor of pork, imparting a subtle, natural sweetness to both the meat and fat. With no lingering heaviness and a refreshingly clean finish, the appeal never tires — and in simple preparations, the quality of the ingredient shines most brilliantly. Whether in salt-grilled or sauté preparations, or in shabu-shabu and braised dishes, the full umami of the pork can be savored to the full. The breed is an LWD three-breed cross — Landrace female × Large Yorkshire male sows with Duroc male. Duroc is a breed known for the umami of its lean and its tendency toward moderate marbling — firmly supporting the rich meat quality and abundant flavor of Ajiwai Pork. By unifying the sourcing of parent pigs to the same farm, the uniformity of bloodline is secured, and by rigorously unifying feed content, individual variation is minimized for consistently stable quality. Raised with devoted care to 160 days, approximately 2,500 head are shipped annually through Ryugasaki Meat Center. Trademark registered with brand standards also established — the assured management system continues to support the maintenance of consistent quality day after day. Please enjoy Ajiwai Pork — a brand pork brimming with the umami nurtured by root vegetables, raised in the rich nature of Namegata City — at your table.
