A pioneer of SPF pork, named for the ancient province of Chiba — 40 years of history that have shaped a superior umami and fat character unlike any other.
Fusa no Meiton Hayashi SPF, bearing the name ‘Fusa’ derived from the old province names of Chiba Prefecture — Kazusa and Shimosa — is a brand pork representing Chiba Prefecture with over 40 years of history as a pioneer of SPF pig (specified pathogen-free) production. Using SPF breeding pigs that have been freed of 5 major specified pathogens from birth, the pigs are raised while maintaining healthy conditions — realizing rearing with vaccines and antibiotic use kept to the absolute minimum. The greatest commitment is the dedicated designated compound feed ‘Hayashi SPF (V)’ given for 60 days (approximately 2 months) before shipment. This original feed — developed over 40+ years — is vitamin and mineral-enhanced with a rich barley blend. Heat treatment at 110°C elevates safety and digestibility, nurturing a water-retentive meat quality and high-quality fat. The pork born of the LWD three-breed cross (Landrace × Large Yorkshire × Duroc) has chewiness yet crispy cutting, with a rich, fragrant umami. The sweetness of the fat and the richness of the meat harmonize in an exquisite balance — widely applicable to tonkatsu, ginger pork stir-fry, and shabu-shabu. Shipped at 185 days of age and 115 kg with devoted care, distributed through major markets including Tokyo Metropolitan Meat Market, Yokohama City Meat Market, and Tosho Town Meat Center. Trademark registered in 1999 with brand standards set in 1980 — the accumulation of many years of quality management and trust is the unwavering strength of this brand. A designated retailer system ensures quality consistency, continuing to deliver pork that consumers can choose with confidence.
