Mejiro Ardan

Mejiro Ardan (Japanese: メジロアルダン, March 28, 1985 – June 18, 2002) was a Japanese thoroughbred racehorse and stud horse. His main victory was at the 1989 Takamatsunomiya Hai. Because of his large build, heavy frame, and distinctive running style in which he stayed low to the ground, he was sometimes nicknamed a "heavy tank" although his legs were considered fragile throughout his life.

His older half-sister Mejiro Ramonu was the first-ever winner of the Fillies' Triple Crown in 1986.
