A Chiba brand pork where feed rice takes center stage — proud of its mellow, rice-derived fat and soft meat quality.
Shizawa Pork Kome Shiage is a Japanese brand pork (meigara-buta) from Asahi City, Chiba Prefecture, managed by Bright Pig Chiba Co., Ltd. Breed / crossbreeding: (Large White ♀ × Landrace ♂) × Duroc ♂ (three-breed cross).
Shizawa Pork Kome Shiage (Shizawa Pork Rice Finish) is a brand pork produced by Bright Pig Chiba Co., Ltd., based in Asahi City, Chiba Prefecture. The pigs are raised using a dedicated liquid feed manufactured by the company itself, and the greatest feature is an original formulation centered on rice-based ingredients including feed rice. By actively incorporating feed rice, the fatty acids derived from rice are reflected in the pig’s fat. As a result, the fat is white and finely grained — a softness and mellow richness that seems to melt when it enters the mouth spreads. Minimal off-odor and an elegant fragrance are also appeals — a finish that tends to be accepted even by those who dislike pork.
Fattening is carried out at Ioka Farm within Asahi City, with a shipping age of 180 days and a shipping weight of 118 kg — raised more slowly than standard pigs. The breed is a three-breed cross (triple cross) — Large White × Landrace sow crossed with Duroc male — a balanced type combining the deliciousness of the lean and the richness of fat.
The rearing environment also provides confidence. Ioka Farm has obtained SQF (Safe Quality Food) certification — managed as a farm that has cleared international food safety standards. Farm HACCP is also in the process of being obtained at all farms — a thoroughgoing approach to hygiene.
Slaughter is carried out at Chiba Prefecture Meat Corporation, with trademark registered in 2010 and brand regulations established in 2009 — a brand with history and track record. Please do enjoy the premium pork flavor unique to the rice finish in a wide range of preparations including stir-fry, shabu-shabu, and tonkatsu.
