The Arima Kinen is a prestigious horse race held annually in Japan, typically in late December. It takes place at the Nakayama Racecourse and is one of the country's most important thoroughbred races, attracting top horses from across Japan. The race is run over a distance of 2,500 meters and is open to both three-year-olds and older horses. This race is unique because it features a special invitation system, allowing only horses that have performed well in designated races throughout the year to compete. The Arima Kinen is often referred to as the "Grand Prix" of horse racing in Japan, making it a highly anticipated event for fans and participants alike.
