Born of an in-house-refined British Berkshire bloodline and bread-crumb feed — the finely grained brand pork of Hidaka, Saitama.
Super Golden Pork is a Japanese brand pork (meigara-buta) from Hidaka City, Saitama Prefecture, managed by Saiboku Co., Ltd. Breed / crossbreeding: Saiboku Hybrid (S) × Duroc male (dam line from in-house-improved British Berkshire stock).
Super Golden Pork is a brand pork produced by Saiboku Co., Ltd., headquartered in Hidaka City, Saitama Prefecture — a company that handles everything from foundation-stock breeding to raising, processing, and sales in one integrated operation. Starting from a small farm founded in 1946, Saiboku has spent more than half a century refining its own breeding stock.
The cross uses ‘Saiboku Hybrid (S)’ — a dam line descended from British Berkshire stock improved in-house — with a Duroc sire. The Berkshire-derived meat is exceptionally fine-grained with a soft mouthfeel, and combined with the umami of Duroc, it achieves a balance that lets you savor the true taste of pork.
The feed is the company’s designated formula (self-compounded), characterized by the use of bread crumbs, which lend the fat a subtle sweetness and a light texture. The pigs are raised at designated farms of the Saiboku group and shipped at a standard of 190 days of age and 115–120 kg — unhurried fattening that concentrates the umami of the meat.
The brand’s history runs deep: its brand regulations were established in 1984. A designated-retailer system enforces quality control, and Farm HACCP has been obtained at some of the group’s farms. An annual distribution of approximately 10,000 head speaks to a production system that balances quality with supply. Active in a wide range of preparations from tonkatsu and shabu-shabu to ginger pork stir-fry and pork miso soup — simple cooking best highlights the fine-grained meat and the gentle sweetness of fat unique to bread-crumb feeding.
