Japan’s Animal Health Sector Gets a Powerful New Player

Strategic Alliance Expands

Ceva Animal Health and Mitsui & Co. have launched Ceva Bussan Animal Health, a joint venture created through the merger of Bussan Animal Health and Ceva Japan. Mitsui transferred 60 percent of its stake in Bussan Animal Health to Ceva, giving Ceva operational control while retaining Mitsui’s strategic support. At the same time, Mitsui strengthened ties further by making an additional equity investment in Ceva.

Blending Experience and Innovation

The partnership combines Bussan Animal Health’s 75 years of experience in Japan with Ceva’s global expertise as one of the world’s leading animal health companies. Bussan Animal Health contributes strong veterinary relationships and deep local market knowledge, while Ceva brings innovative livestock and pet healthcare products, along with expertise in over-the-counter pet solutions. Together, the companies aim to provide a broader product portfolio and improved services for veterinarians, farmers, and pet owners across Japan.

According to Towards Healthcare, the Asia Pacific animal health market is projected to experience significant growth, with estimates suggesting the market size will increase from USD 60.74 billion in 2026 to approximately USD 152.88 billion by 2035, representing a compound annual growth rate (CAGR) of 10.8% from 2026 to 2035. According to Towards Healthcare, the Asia Pacific animal health market is projected to grow strongly, driven by rising pet ownership, livestock healthcare investments, veterinary innovation, and awareness of disease prevention.

A Stronger Platform for Growth

The new venture is designed to strengthen market reach, improve operational efficiency, and support future product launches in Japan’s rapidly evolving animal health industry. Bussan Animal Health generated nearly €40 million in revenue in 2025, while Ceva Japan adds commercial, regulatory, and marketing expertise alongside products focused on swine, ruminant, and pet health.

Leadership for the Future

Former Ceva Japan Managing Director Tadahiro Ohashi has been appointed CEO of the joint venture, while former Bussan Animal Health CEO Akito Umeda will serve as Deputy CEO. Both companies say the collaboration reflects their long-term commitment to sustainable growth and innovation in Japan’s animal health market. Executives from both organizations described the venture as a milestone partnership that will deepen customer engagement, accelerate innovation, and create lasting value for Japan’s veterinary and animal healthcare sectors while strengthening the companies’ long-term strategic ties.

A recent report by Towards Healthcare highlights that the Asia Pacific animal health market is witnessing growth due to expanding veterinary services, biosecurity measures, technological advancements, and demand for care.
