Far more marbling than usual — a Saitama brand pork proud of a sweetness that melts in the mouth.
Bushu Sashi-ton is a Japanese brand pork (meigara-buta) from Konosu City, Saitama Prefecture, managed by Aihara Chikusan Co., Ltd. Breed / crossbreeding: Three-breed cross: Female (Landrace × Large White) × Male Duroc.
Bushu Sashi-ton (Bushu Marbled Pork), produced by Aihara Chikusan Co., Ltd. in Konosu City, Saitama Prefecture, is a brand pork whose name embodies the remarkably abundant sashi (marbling) — rare in pork. Compared to standard pork, the sashi is far greater — the cross-section of red and white beautifully harmonized is reminiscent of premium beef. When tasted, the fat melts as if dissolving — sweetness and softness spreading simultaneously. The clean, refreshing finish is unrelated to the cloyingness characteristic of pork, and you find yourself reaching for another bite.
One secret producing this abundant sashi is the dedicated compound feed ‘Big Marble Fattening Pork M.’ Giving this feed designed for easy sashi formation draws out the fineness of fat marbling. Furthermore, Bushu Sashi-ton contains more unsaturated fatty acids than standard pork — particularly oleic acid in abundance. Oleic acid is said to lower bad cholesterol, underpinning the sweetness and approachability of the fat. Precisely because the fat is delicious, the melt-in-the-mouth texture and lingering flavor are realized.
The breed is a three-breed cross — Landrace × Large White sows with Duroc male. Duroc is known as a breed with easy marbling, bringing abundant fat marbling and a high-water-retention meat quality. Shipped at 180 days of age and approximately 115 kg — fully matured before shipment.
2,000 head are distributed annually through designated retailers, with the trademark registered in 2007. Particularly suited to preparations that allow the umami of the fat to be savored, such as shabu-shabu and yakiniku.
