Born of unified breed lines and a devoted commitment to feed — a pure, honest pork taste that southern Shinshu is proud of.
Junmiton (Pure Flavor Pork), in the southern tip of Nagano Prefecture — South Shinshu, Shimoina District — is a brand pork with over 30 years of history. With JA Zen-Noh Nagano Prefecture Headquarters as the managing body, a unified production system at designated farms has maintained stable quality — a brand pork representing the region. Its defining feature is the rearing philosophy of drawing out the authentic flavor of pork directly. Aligning the lineage of breeding pigs and giving a consistent, committed compound feed to fattening pigs for 180 days, the pigs are slowly and carefully raised. Shipping weight is 110–125 kg — appropriately controlled — realizing a meat quality of well-balanced lean and fat. Consumer voices including ‘the quality and umami of the fat is different’ and ‘absolutely no off-odor’ speak to the quality. The breed is LWD three-breed cross — Landrace × Large Yorkshire female crossed with Duroc male. Combining the advantages of each breed, both softness and richly flavored meat quality are achieved. The distribution style of ‘visible-face sales’ connecting producers and consumers is also one of Junmiton’s appeals. The primary sales destinations are stores of long-established supermarket ‘Kiraya’ — rooted in South Shinshu, Shimoina District. Kiraya, with over 200 years of history since founding, has long handled Junmiton as its own original brand — cherished by local residents. As a preparation, shabu-shabu — where the umami of the fat and the softness of the lean stand out — is particularly recommended. In char siu using belly meat and simple ginger pork stir-fry as well, the authentic sweetness and flavor of the pork can be savored. Please do pick up Junmiton at Kiraya on a visit to South Shinshu and experience its pure pork flavor.
