A pioneer of SPF pork, named for the ancient province of Chiba — 40 years of history that nurture fine-quality umami and fat flavor.
Fusa no Meiton Hayashi SPF is a Japanese brand pork (meigara-buta) from Tonosho Town, Katori District, Chiba Prefecture, managed by Hayashi Shoten Pig Shipping Association. Breed / crossbreeding: (Landrace ♀ × Large White ♂) × Duroc ♂ (LWD three-way cross).
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 vaccine and antibiotic use kept to a 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 wheat 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 White × Duroc) has chewiness yet a clean, crisp bite, 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 Tonosho Town Meat Center. Trademark registered in 1999 with brand regulations 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.
