Umi no Mineral Ton

Hokkaido’s pride — a healthy brand pork raised on deep-sea minerals and cereal grains.

Umi no Mineral Ton is a Japanese brand pork (meigara-buta) from Shibetsu City, Hokkaido, managed by Nakatayoro Farm Co., Ltd. Breed / crossbreeding: Female: Camborough × Male: PIC800.

Raised in the rich natural environment of Shibetsu City, Hokkaido, Umi no Mineral Ton (Sea Mineral Pork) is a brand pork with a distinctive concept — incorporating deep seawater minerals and carefully selected rock salt into its feed. The abundant mineral content of deep seawater elevates the umami of the pork and suppresses the off-odor typical of ordinary pork, delivering a clean, fresh fragrance and a healthy, approachable eating experience.

The feed incorporates cereal grains such as barley and wheat at a ratio of 10% or more, while the finishing stage uses absolutely no fishmeal or meat meal whatsoever. The fusion of grain-derived sweetness and seawater minerals creates a refreshing, never-heavy flavor that brings out the inherent taste of pork. The rearing period is 155 days, producing a meat that is not overly marbled, with the umami of the lean clearly felt.

Production is managed by Nakatayoro Farm Co., Ltd. (Hakusan Farm) under the Kamikawa Swine Promotion Association, holding both Farm HACCP and JGAP certification for integrated hygiene and quality management from rearing through to shipment. 16,000 head are shipped annually through major meat processors within and outside Hokkaido, such as Starzen Meat Processor (Ishikari and Misawa plants) and Nippon Food Packer (Doto plant). Major food companies including Ito Ham, Nippon Ham, and Prima Ham also use it as a raw material — its reliable quality is widely recognized.

Raised with care in Hokkaido’s abundant natural environment, drawing on the power of sea minerals — please do try Umi no Mineral Ton at least once.
