Raised on the pure spring water and dedicated feed of the Nasu foothills — a three-way cross brand pork of rich, full umami.
Nasu Sanroku-ton (Nasu Foothill Pork) is a brand pork consistently managed by Zenchiku Nasu Sanroku Farm Co., Ltd., based at Senbonmatsu Farm spreading across the Nasu foothills in Nasu Shiobara City, Tochigi Prefecture. The breed is a three-breed cross — Landrace × Large Yorkshire sows with Duroc male — characterized by a meat quality that combines softness, umami, and the sweetness of fat at a high level. At this farm, the mineral-rich, crystal-clear natural water welling up in the rich natural environment of the Nasu foothills is used as drinking water — the commitment to water quality being one of the important factors elevating the umami of the pork. The feed uses a dedicated compound balanced primarily with corn and barley, raised slowly under safe management in compliance with the Feed Safety Law. By fattening patiently to 185 days — longer than standard pigs — the grain of the lean becomes fine, with a subtle sweetness and rich fragrance added to the fat. The pork born of such devoted rearing firmly seals in meat juices even after heat cooking — the smooth melt-in-the-mouth and lingering umami can be enjoyed to the full when eaten. Freshness and quality retention are also highly reputed, with the cookability and stable eating quality earning high praise from professional chefs. Participation in the farm traceability system also ensures transparency of production information — a reassuring point for consumers. Nasu Sanroku-ton, trademark-registered in 2013, is a highly reliable brand pork managed under reliable quality standards — delivered to tables throughout the country, starting from local Tochigi.
