Shonai Green Pork Boomin

Nurtured by the rich land of Shonai — a select brand pork with a light sweetness drawn out by rice and cereal grains, processed in a highly hygienic environment.

Shonai Green Pork Boomin is a Japanese brand pork (meigara-buta) from Yamagata Prefecture, managed by ZEN-NOH Yamagata Prefectural Headquarters. Breed / crossbreeding: LWD three-breed cross (Landrace × Large White × Duroc).

Shonai Green Pork Boomin (SHONAI GREEN PORK BOOMIN) is a select brand within ‘Shonai Green Pork’ — the brand pork developed by the JA Group in Yamagata’s Shonai district — a designation available only to pigs at registered farms that meet strict standards of breed and feed. The name ‘Boomin’ is a pet name meaning ‘everyone’s pig,’ given with the wish of connecting the love of producers with the smiles of those who eat.

The Shonai region faces the Sea of Japan and is known as a rich agricultural area nourished by snowmelt water from Mount Chokai and Mount Gassan — a land that has nurtured high-quality agricultural produce including ‘Shonai Rice.’ In this rich natural environment, a unified breed of LWD three-breed cross (Landrace, Large White, Duroc crossbred) is raised on a dedicated feed combining rice (feed rice) and cereal grains such as barley and wheat — producing a fat of refreshingly clean sweetness with suppressed heaviness, and a moist, tender lean. The use of feed rice contributes not only to meat quality improvement, but also to the conservation of rice paddies in the Shonai plain and the resource circulation of regional agriculture.

Slaughter and processing are carried out in an integrated system at Shonai Meat Distribution Center, with the meat processed in an advanced hygienic environment with no direct contact with outside air — delivered fresh. Available at mass retailers within Yamagata Prefecture including A-Coop, as well as through JA Town direct-delivery mail-order and furusato nozei. Also popular in processed product forms such as shabu-shabu, loin cutlet, and wieners — a brand pork that allows easy enjoyment of the rich food culture of Shonai.
