Ceva Animal Health and investment company Mitsui & Co., Ltd have announced the creation of Ceva Bussan Animal Health, a new joint venture that brings together Bussan Animal Health (BAH) and Ceva Japan. 

As part of the transaction, Mitsui has transferred 60% of its shareholding in BAH to Ceva. Ceva Bussan Animal Health will be operated by Ceva as a controlling shareholder and benefit from Mitsui’s ongoing support as a leading global trading and investment company headquartered in Japan.

In parallel, Mitsui has made an additional strategic equity investment in Ceva, further reinforcing the long-standing partnership between Ceva and Mitsui.

Ceva and Mitsui have built a long-standing strategic partnership in the animal health sector, combining Ceva’s global expertise as a leading animal health company with Mitsui’s extensive global reach and diverse business portfolio.

This enhanced partnership is intended to accelerate collaboration across broader initiatives, including innovation, market expansion and the creation of long-term sustainable value in the animal health industry.

Ceva Bussan Animal Health represents a cornerstone of this reinforced collaboration, providing a concrete operational platform in Japan.

Ceva Bussan Animal Health combines BAH’s 75-year heritage in the Japanese animal health market with Ceva’s position as a global top five animal health company. BAH brings a strong and longstanding presence in the veterinary channel, while Ceva provides access to leading livestock and pet products, and to future innovation. Ceva also adds recognized multichannel expertise, particularly in OTC pet products. 

Together, these complementary capabilities create a company with a broader and more complete product range for the Japanese market.

BAH generated approximately €40 million in revenue in 2025 with deep experience serving veterinarians and pet owners.

Ceva Japan contributes a lean team with robust commercial, marketing and regulatory capabilities and a solid portfolio with existing and future products covering swine, ruminant and pet health products.

Marc Prikazsky, Executive chairman of Ceva Animal Health, commented: “With Ceva Bussan Animal Health, we are opening a new chapter for animal health in Japan. By combining the deep roots and expertise of BAH with Ceva’s global innovation capabilities, we are creating a company uniquely positioned to better serve veterinarians, farmers, and pet owners. This joint venture reflects our long-standing commitment to the Japanese market and our ambition to accelerate growth by building strong, local partnerships. Together with Mitsui, we are laying the foundations for a stronger, more dynamic future for animal health in Japan.”
