Nurtured by the nature of Oze — a Gunma brand pork of juicy, smooth richness that refreshes with every bite.
Oze Pork is a brand pork raised in the rich natural environment of Numata City, Gunma Prefecture, blessed with clear air and pure water. Tone Numa Dream Farm, which handles the rearing, has made a commitment to creating a rearing environment with stress eliminated as much as possible, prioritizing above all else the health of the pigs. The barns are spaciously designed to secure space where the pigs can relax, with individual IC tags attached to each piglet to manage growth conditions individually — preventing disease before it occurs and realizing the raising of healthy pigs without reliance on medication. Furthermore, by incorporating Good Agricultural Practice (JGAP), recording, inspecting, and evaluating the production process systematically, effort is put into producing highly safe pork. There is also a proprietary commitment to feed — a dedicated feed incorporating whey containing ‘catechin’ (a tea-derived component), centered on grains including corn and barley, is given. The pork produced by this careful rearing environment and special feed is characterized by a great juiciness spreading from the first bite. The balance between soft, pleasant lean and mellow, elegant fat is exquisite, with the rich umami standing out more with every bite. In 2017 it obtained a trademark, with Farm HACCP in 2018 and JGAP certification in 2020 — a brand whose sincere stance toward quality and safety has been steadily recognized. Also handled by supermarkets within Gunma Prefecture and the Yukoop consumer cooperative (Kanagawa, Shizuoka, and Yamanashi Prefectures), it is a brand pork easily enjoyed by those in the Kanto and Tokai areas.
