Refined by Jiyoso and a grain finish — an Ibaraki brand pork of mild, overflowing umami.
Ibaraki Jiyoton is a Japanese brand pork (meigara-buta) from Ibaraki Prefecture, managed by Iijima Chikusan Co., Ltd. Breed / crossbreeding: Female (Landrace × Large White) × Male: Duroc (three-way cross).
Ibaraki Jiyoton is a brand pork from Ibaraki Prefecture, raised under a devoted feed program and thorough hygiene management by Iijima Chikusan Co., Ltd., based in Hokota City — with pronounced sweetness and richness. The breed is a three-breed cross of Landrace, Large White, and Duroc — characterized by a well-proportioned meat quality and moderate fat balance.
In rearing, a feed incorporating ‘Glow Rich’ is given from the sow and piglet stage. When the pigs grow into fattening pigs, a supplement called ‘Jiyoso’ — made from wood vinegar distillate, zeolite, seaweed, and mugwort — is added. Furthermore, beginning 2 months before shipment, the dedicated Jiyoton feed with 82%+ grains and approximately 30% cereal grains such as barley and wheat is combined — drawing out the umami of the meat to the maximum. Through this accumulation of staged feed design, the characteristic pork off-odor is substantially reduced, and cholesterol tends to be lower as well. Slow discoloration and minimal drip loss are also characteristics — the inherent umami and vivid appearance of the ingredient are preserved for longer.
At the farm, group-unit rearing and management is rigorously maintained, and each time a group is shipped, the barn is vacated completely and washed and disinfected in its entirety — thoroughly resetting the hygienic environment to ensure stable supply of safe, reliable meat. The pork, finished over 185 days of rearing, has an exquisitely balanced umami and sweetness — capable of transforming everyday dishes like hearty pork curry into a special meal.
