Raised on the crystal spring water and gifts of great nature in Nasu-Shiobara, Tochigi — a brand pork of uncompromising character.
Senbonmatsu-ton (Senbonmatsu Pork), nurtured in the lush Senbonmatsu district of Nasu Shiobara City, Tochigi Prefecture, is a brand pork raised with devoted care on pure spring water originating from the Nasu foothills, and a feed centered on corn and barley. The managing body is Zenchiku Nasu Bandai Farm Co., Ltd., using safe feed in compliance with the Feed Safety Law and raising pigs healthily under thorough disease prevention and hygiene management. The breed is LWD three-breed cross — Landrace × Large Yorkshire sows with Duroc male — a well-balanced breed composition contributing greatly to the stability of meat quality and richness of umami. Also particularly noteworthy is the length of the rearing period. By fattening slowly and patiently to 200 days — longer than standard pigs — a deep flavor and rich depth accumulates firmly within the meat. The fat has an elegant, clean finish — never cloying no matter how much is eaten. While the meat quality is firm, the rich umami that spreads when it enters the mouth is a flavor impossible to forget once tasted — with yakiniku and steak drawing out its appeal to the maximum. Senbonmatsu-ton — supported by crystal-clear water and safe feed, raised with time and care — is shipped with freshness and quality given absolute priority, maintaining outstanding condition when it reaches the table. Please do enjoy this Nasu brand pork — every bite carrying the bounty of Nasu’s great nature and the producer’s commitment — at your home table.
