Kyoto Biken Laboratories

What Kyoto Biken Laboratories does

Kyoto Biken Laboratories (株式会社微生物化学研究所, also known as 京都微研) is Japan's first private veterinary vaccine manufacturer, founded in June 1948 in Kyoto. The company specializes in the development, manufacturing, and supply of vaccines for cattle, pigs, poultry, small animals (dogs and cats), and aquaculture (fish), along with diagnostic reagents for post-vaccination antibody testing, plant vaccines, and specialty feed products (A飼料). Its core technology centers on immunostimulation-based disease prevention — generating antibodies in animals rather than treating infections with antibiotics — supported by an integrated R&D-to-supply chain and dedicated SPF (Specific Pathogen Free) manufacturing facilities at the Miyazu Branch. Kyoto Biken holds the No. 1 domestic market share in Japan's bovine vaccine market, built through decades of close engagement with livestock farmers and dealers, and operates a multi-building manufacturing and research complex in Uji, Kyoto.

The company generates revenue primarily through one-time sales of its veterinary vaccine and related product portfolio to livestock farmers, veterinarians, and aquaculture operators, distributed via a regional network of dealers and distributors across Japan, with direct sales to veterinary healthcare professionals. Pricing is quote-based and not publicly disclosed. Internationally, Kyoto Biken has expanded through its wholly-owned subsidiary, Kyoto Biken Hanoi Laboratories, Co., Ltd., established in July 2011 in Vietnam as the first offshore operation, targeting Southeast Asian markets with a 'Made in Vietnam + Japan Quality' positioning. The company currently markets through its corporate website (kyotobiken.co.jp) and is undergoing a corporate integration scheduled for July 1, 2026, when Kyoto Biken will merge with Sasaeah Holdings Co., Ltd. and Fujita Pharmaceutical Co., Ltd. to form Nippon Virbac Co., Ltd., consolidating their R&D, production, and import operations.
