Raised in the great land of Ibaraki beneath the gaze of Mount Tsukuba — a brand pork that delivers both peace of mind and abundant umami.
Yumibuta is a brand pork consistently produced by Yumino Livestock Co., Ltd., based in Ishioka City, Ibaraki Prefecture. In a rich natural environment overlooking Mount Tsukuba — the ‘Purple Peak’ (Shiho) — the pigs are raised with care in spacious, well-ventilated barns, growing in ample space with stress kept to a minimum. The farm draws from abundant, long-accumulated groundwater, with a deep commitment to the quality of the water that supports each pig’s health. The feed is a carefully crafted proprietary blend based on the Yumibuta-dedicated compound, enriched with eucommia tea, lactic acid bacteria, Korean ginseng, and garlic — steadily and patiently supporting the immune system and constitution of the pigs through daily accumulation. The farm is certified by the Japan SPF Pig Association, with rigorous hygiene management in place and the health of every individual confirmed without fail each day. This careful, time-intensive rearing produces a pork of minimal off-odor and a finely-grained meat quality. When eaten, an elegant sweetness of fat spreads gently, and a rich depth of flavor is felt within the delicate texture. The high-quality fat has a pleasant, light mouth feel, and its umami remains almost unimpaired whether warm or cooled — a point long valued by chefs who have worked with Yumibuta for years. Equally capable of delivering straight umami in shabu-shabu or steak as it is versatile in yakiniku, braised pork, and tonkatsu — a brand pork with remarkable range. Please do experience this carefully crafted animal, nurtured by the bounty of Ibaraki’s Mount Tsukuba, at your table.
