Hanshin Racecourse was built in 1949 on the site of a former aircraft plant called Kawanishi Aircraft Company that manufactured fighting planes during the World War II at Komanocho in Takarazuka in Japan. After the World War II, the authorities ordered the company to stop the production of combat planes which brought about a closure to the concern. In 1949, the Hanshin Racecourse was built by Keihanshin Keiba K.K. and is considered as the second racecourse in Western Japan (next to Kyoto Racecourse). Kyoto and Hanshin have equal numbers of race meetings and both of them alternate race meeting. Some of the most prominent races hosted in Hanshin Racecourse include the Oka Sho (or the Japanese 1000 Guineas), the Takarazuka Kinen, the Hanshin Juvenile Fillies and the Asahi Hai Futurity Stakes.
