Focuses on the regulation of reproductive function and hormonal actions in horses and the development of diagnostic measures. Also studies various problems related to the broodmare’s production management. Aims to contribute to the development of community-based horse industry. Envisages the promotion of education, research, and social actions through horses as the future goal. “Think globally! Act locally!”

List of current research topics

  • Artificial insemination and transplantation of fertilized eggs (embryos) using Hokkaido Horse (Dosanko) and Connemara Horse
  • Production medicine of heavy draft horses
  • Clarification of reproductive endocrinology during equine pregnancy
  • Establishment of a new hormonal diagnostic measure concerning equine reproductive disorders
  • Development of non-contact body measurement using 3D camera
