Raised in Hirono Town, Iwate — a trusted, SPF-certified brand pork you can enjoy with complete peace of mind.
Hachimantai Pork Ai is a brand pork raised in the rich natural environment of Hirono Town, Kunohe District, Iwate Prefecture. At the farm managed by Hachimantai Farm Agricultural Corporation — an SPF-certified farm — pigs free of specific pathogens are raised under a strict disease prevention system, with a veterinary clinic on the premises and a dedicated resident veterinarian monitoring the health of the pigs day by day. A temperature and ventilation control system applying the latest European technology has been installed, creating a comfortable rearing environment in which pigs can live without stress. Only compound feed prepared by specialist organizations is used in rearing, with no self-sourced ingredients used at all — ensuring the safety and uniformity of quality of the feed. Liquid feed (water added to feed to create a liquid) is also adopted, a measure that prevents a drop in feed intake even in summer. The pork produced in this way is characterized by a finely-grained, juicy lean with minimal gamey off-odor and easy approachability. The fat has a satisfying richness without being greasy, and the aftertaste is refreshingly clean. The Japan Livestock Products Grading Association’s grading consistently achieves a superior and standard quality ratio of 90% or more — stable quality earns high regard from commercial users and restaurants alike. Shipping age is 150–160 days, with approximately 40,000 head shipped annually via Iwachiku and the Kuji Wide-Area Meat Processing Center, distributed nationwide through ZEN-NOH Iwate Prefectural Headquarters. The meat remains tender even after cooling — making it valued for bento and prepared foods — and it is a brand pork enjoyed by many, active everywhere from family tables to professional food service settings.
