The national championships of the different branches of the martial arts (judo, kendo, karate, aikido, etc.)
are held annually at the Budokan.
The Budokan has also been associated with professional wrestling's big shows, typically from All Japan Pro Wrestling and Pro Wrestling Noah.

K-1, Shooto and Pride Fighting Championships have all held events at the arena.
