Raised on Fukaya-grown satsumaimo sweet potato — a Saitama brand pork where sweetness and richness melt together.
Saitama-kensan Imobuta is a Japanese brand pork (meigara-buta) from Saitama Prefecture, managed by Chubu Shiryo Co., Ltd., Meat Development Sales Department. Breed / crossbreeding: Female (Landrace × Large White) × Male: Duroc (three-breed cross).
Saitama-kensan Imobuta (Saitama Prefecture Sweet Potato Pork), born in Fukaya City, Saitama Prefecture, is a unique brand pork that incorporates locally grown sweet potato into its feed. Fukaya City is nationally known as a scallion production area, but the initiative of utilizing sweet potatoes grown on the same rich land as pig feed creates a distinctive meat quality.
The feed combines Fukaya City-grown feed-use sweet potato with compound feed. Sweet potato is a plant-based ingredient richly containing sugar and starch — when it is given to pigs, the fat melting point lowers, and an elegant fat sweetness that gently melts from the moment it enters the mouth is born. Furthermore, glutamic acid and aspartic acid — umami components — increase, with a deep flavor spreading with every chew.
The breed is a three-breed cross — Landrace × Large White sows with Duroc male — known for the richness of lean umami and solid build. The finely grained, soft meat quality and mellow fat balance shine in a wide range of preparations including tonkatsu, ginger pork stir-fry, and shabu-shabu.
Shipping is at 190 days of age, approximately 115 kg, slaughtered at the hygienically excellent Honjo Meat Center. The managing body, Chubu Shiryo Co., Ltd. Meat Development Sales Department, maintains a safe rearing environment and thorough quality management. The brand trademark was registered in 2008, with brand regulations also established the same year — a local brand with history. Please do try Imobuta — approximately 9,000 head shipped annually — at your table at least once.
