Yushun Himba
Before the year 2001, it was the only colt and fillies G1 race that non-Japanese bred three-year-olds could participate, which led to this race being considered as the "Japanese Derby for non-Japanese bred horse" until foreign-bred horse restrictions were lifted in 2001. Until 2010 it was limited to domestic-trained horses, but these restrictions were removed that year (along with the Japanese classics). A maximum of nine foreign horses are allowed entry in the NHK Mile Cup. It is considered one of the prep races for both the Yushun Himba (the Japanese Oaks) and the Tokyo Yushun (the Japanese Derby).
