A Gift from Nature

Looking for practical solutions to livestock methane, natural production, or sustainable feed?
 We may be able to help.

 For over 40 years, we have worked quietly at the intersection of soil science, fermentation, and livestock health — developing a system that reduces dependency on antibiotics, improves feed efficiency, and supports healthier animals from the inside out.

 This is not a product company. It is a technology company that has spent four decades refining one thing: the conditions in which great livestock are born.

Kakegawa Yeast-Fermented Feed

Four decades of dedication, refined into a single fermentation system.
 When Kakegawa Yeast is introduced into grain, alcohol fermentation occurs naturally — sterilizing the material and converting it into a high-quality amino-acid-rich feed. The resulting feed promotes blood circulation, supports natural growth, and eliminates stress in animals, producing meat of exceptional texture and fat quality.

 The philosophical and scientific foundation of this technology is inseparable from the lifelong research of Dr. Kubota, a soil science authority whose knowledge of natural farming systems forms the core of the approach. His work continues to inform the methodology applied in field trials today.

Safe — Pharmaceutical-Free Rearing


 Livestock raised on Kakegawa Yeast-Fermented Feed are reared exclusively on sterilized fermented feed. No antibiotics or pharmaceuticals are used at any stage.
(The “fattening period” refers to the phase following weaning, during which animals are transitioned to grain-based feed.)

Integrated — From Feed to Farm

 Our production system maintains full responsibility across the entire chain — from the preparation of yeast-fermented feed through to animal rearing — under a single, integrated management structure.

Healthy — Exceptional Fat Quality

 The difference begins with fat composition.
 Livestock raised on Kakegawa Yeast-Fermented Feed benefit from improved blood circulation and natural fat metabolism. The result is meat with low saturated fat, high unsaturated fatty acid content, and a clean, full flavour with no animal odour. Tender, fine-grained, and consistently praised for its juiciness. (Olive oil contains more than 80% unsaturated fats.)

Full-Ripened — Extended Maturation

 Following standard rearing, animals undergo an additional maturation phase of more than two weeks on a reduced-calorie Kakegawa Yeast-Fermented Feed. The result is a depth of umami that distinguishes this meat from conventional production.

Patent History
Patent No. JP3950767 (term expired)
Title: Fermentation Yeast for Organic Feed Production and Manufacturing Method
Inventor: Tsuneo Kakegawa
This is the foundational patent underlying the technology. Expiry reflects the natural term of protection, not the end of the technology's development. Field application has continued for over 40 years since the original filing.

Challenges We Are Currently Addressing

 We are currently working with research institutions and industry partners on the following areas:

  • Livestock methane reduction
  • Carbon & ESG initiatives in livestock production
  • Natural and antibiotic-free livestock production
  • Circular food systems and food by-product utilisation
  • Feed innovation and feed efficiency improvement
  • Animal gut health and natural immunity

 If your organisation is facing similar challenges, we would be pleased to discuss possible collaboration.

Every project begins with a challenge. Sometimes, the right solution is already waiting — it simply has not been connected yet.
