Tōkyō Yūshun

The Tōkyō Yūshun (東京優駿), also called the Japanese Derby (日本ダービー, Nippon Dābī) is a Grade 1 flat horse race in Japan for three-year-old thoroughbred colts and fillies. It is run over a distance of 2,400 metres (approximately 1 mile 4 furlongs) at the Tokyo Racecourse, Fuchū, Tokyo in late May or early June.

It was first run in 1932 and is the Japanese equivalent of the English Epsom Derby. It is the second leg of the Japanese Triple Crown, preceded by the Satsuki Shō (the Japanese equivalent of the English 2,000 Guineas) in mid-to-late April and followed by the Kikuka Shō (the Japanese equivalent of the English St. Leger Stakes) in mid-late October.

Since 2010, the Tokyo Yūshun (along with several other JRA Japanese domestic Grade 1 races, including the other Japanese classics such as the Satsuki Shō and the Kikuka Shō) is open to international competition due to Japan's inclusion in the International Federation of Horseracing Authorities' ICS Part I category, in which all graded black-type races in the JRA calendar are open to international competition. Races prior to 2001 (along with the other Japanese classics) were only limited to Japanese-bred horses. Since 2001, foreign-bred horses are allowed, but until 2010 this race (and the other classics) were only limited to Japanese-trained horses. Since 2010, up to 9 foreign-trained or bred horses can enter the race.
