Investing in Happy Neko-chan Wan-chan Corporation to Connect a Better Future for Cats and People Through an FECV Eradication Drug

Miraidoor Corporation (Headquarters: Minato-ku, Tokyo; Chairman and President: Daisuke Sawada; hereinafter "Miraidoor") announces that it has made an investment through the Howa Startup and Business Succession Support Investment Limited Partnership (hereinafter "Howa Startup and Business Succession Support Fund"), which it established jointly with Howa Bank Ltd. (hereinafter "Howa Bank"), in Happy Neko-chan Wan-chan Corporation (Headquarters: Oita City, Oita Prefecture; President: Shigeru Matsuoka; hereinafter "Happy Neko-chan Wan-chan"), a company developing a drug to eradicate feline enteric coronavirus. This funding support will be provided in cooperation with the "Oita VC Success Fund No. 7 Investment Limited Partnership" operated by Oita Venture Capital Corporation, a subsidiary of Oita Bank Ltd. Regional financial institutions within Oita Prefecture will collaborate to support the company's growth. ◆About the Investee Company Happy Neko-chan Wan-chan is a university-launched startup developing a drug to eradicate feline enteric coronavirus (hereinafter, FECV), based on research achievements from Oita University and Kitasato University. FECV is a virus estimated to infect about 40% of domestic cats, and if left untreated, the infection can potentially lead to feline infectious peritonitis (hereinafter, FIP), a fatal disease. Currently, there are no officially approved effective treatments or vaccines for FIP domestically or internationally, making it the third leading cause of death in cats. Through the practical application of an FECV eradication drug that targets FECV in the intestines and eradicates it before it mutates into FIP, Happy Neko-chan Wan-chan aims to realize a better future for cats and people.
