Voice actress Kaori Maeda has sparked a buzz on her X account by posting a message celebrating the birthday of Nice Nature, the character she voices in the game "Umamusume: Pretty Derby."
The real-life racehorse that served as the motif, Nice Nature, was born on April 16, 1988, and passed away on May 30, 2023. The "Nice Nature Birthday Donation" campaign—organized by the Certified NPO Retired Horse Association to support the post-racing lives and future of retired horses (primarily local stakes winners)—has continued even after the horse's passing and is still ongoing as of 2026. He remains a legendary horse who was deeply loved by fans during his racing career, his retirement, and even after his death.
