Memuro-san SPF Ton

Memuro-san SPF Ton is a Japanese brand pork (meigara-buta) from Shoei, Memuro Town, Kasai District, Hokkaido, managed by Sasaki SPF Farm. Breed / crossbreeding: Female (Large White × Landrace) × Male Duroc; W: Hamanasu W2, L: Zenno L1, D: Sakura 201.

Memuro-san SPF Ton is a brand pork produced by Sasaki SPF Farm, located in Memuro Town in the Tokachi region of Hokkaido. SPF stands for ‘Specific Pathogen Free’ — pigs free of specific pathogens as designated by the Japan SPF Swine Association.

The farm limits the number of pigs to a scale manageable by just three family members, putting devoted individual attention into every animal every day. Strict hygiene protocols — including mandatory bathing and changing into dedicated clothing before entering the barn — maintain a rigorously clean rearing environment, realizing a healthy rearing style that does not rely on antibiotics. The farm also practices circular agriculture, returning pig manure as compost to neighboring crop fields, coexisting with Tokachi’s excellent agricultural land while maintaining a sustainable production style.

The pigs are raised on the pure waters and clear air of Tokachi, using a designated compound feed specific to SPF pigs over 165 days, and the resulting pork is virtually free of pork off-odor — characterized by a finely grained meat quality and excellent moisture retention. The fine muscle fibers retain umami firmly, so the moist, tender texture persists long after cooking. Whether in shabu-shabu, grilled preparations, or other simple dishes that let the ingredient shine, the quality of flavor stands out fully.

Annual shipments are limited to just 650 head, distributed primarily within Hokkaido through Hokuren Federation of Agricultural Cooperatives. Please do try this rare pork — packed with the sincere effort of this farm.
