Only the finest sows, carefully selected. Six grains of feed nurture a richness and umami of the highest quality.
Rokkoku Otome Buta, with Ibaraki Prefecture as its primary production area, is a brand pork whose name embodies the commitment to selecting and shipping only female pigs. As the name ‘otome’ (maiden) suggests, all pigs shipped are exclusively female — and this selection criterion is the greatest distinction from other brand porks. In general, female pigs tend to have more finely-grained muscle fibers and are less prone to the characteristic off-odor of pork compared to castrated males. To further draw out this premium meat quality unique to female pigs, an original feed made from six grains with a high barley content is used. A designated compound feed balanced with wheat, barley, rice, corn, milo, and soybean is given, nurturing a deep, grain-derived umami and elegant richness within the pork. The breed is a three-breed cross — Duroc male with Landrace female × Large Yorkshire male female sow — raised carefully to approximately 180–190 days. The management body is I-Pork Co., Ltd. (Ito Ham-Yonekyu Holdings Group). With annual shipments limited to approximately 9,000 head, it is not always easy to come by — so when you see it, please do pick it up. The fat is brilliant white and clean, and when eaten, a natural grain-derived sweetness and mellow richness spread through the mouth, with a refreshingly clean finish. In simple preparations like shabu-shabu and ginger pork stir-fry that let the ingredient shine, the full appeal can be enjoyed to the maximum. Please savor the delicate meat quality of these female pigs and the rich flavor born of grain feed at your table.
