Eco no Mori Waraibuta

Raised on food-loss feed in Akita — a rare hybrid brand pork, lighter in calories, with a soft umami that stands out.

Eco no Mori Waraibuta is a Japanese brand pork (meigara-buta) from Yokote City, Akita Prefecture and Kanegasaki Town, Isawa District, Iwate Prefecture, managed by Sugayo Co., Ltd. Breed / crossbreeding: TOPIGS20 (hybrid).

Eco no Mori Waraibuta (Eco no Mori Eco-Boo) is a brand pork managed and produced by Sugayo Co., Ltd., based in Yokote City, Akita Prefecture. The brand’s wish — to realize a table where the whole family gathers in smiles — is inscribed in the name itself. Rearing takes place at company-owned farms in Yokote City, Akita, and Kanegasaki Town, Iwate, with a distinctive rearing system built at each farm in connection with the local food culture.

The defining feature is a liquid fermented feed system called ‘liquid feeding.’ An eco-feed — fermented food loss such as bread and noodles with the addition of whey and lactic acid bacteria — is given daily, raising pigs while simultaneously achieving both reduction of food waste and reduction of CO2 emissions. By adopting this advanced method widespread in Europe, the farm maintains a high standard of pig health while minimizing environmental impact.

The breed is TOPIGS20 — a hybrid pig that is mainstream worldwide but accounting for only a few percent of pigs raised in Japan, making it a rare bloodline domestically. This unique combination of rearing method and breed produces pork with approximately one-third fewer calories and lower cholesterol levels compared to standard pork. The meat quality is finely grained and tender, the fat carries an elegant sweetness and rich umami, and it pairs particularly well with shabu-shabu and sliced preparations.

The shipping age is 140 days, with annual shipments of approximately 31,000 head. The trademark was registered in October 2008, and it is also widely enjoyed as a furusato nozei (hometown tax donation) return gift in both Akita and Iwate prefectures.
