Freestyle one-step sparring is similar to one-step sparring but requires the karateka to be in motion. Practicing one-step sparring improves free sparring (jiyu kumite) skills, and also provides an opportunity for practicing major counter-attacks (as opposed to minor counter-attacks). Tsutomu Ohshima states that freestyle one-step sparring is the most realistic practice in Shotokan Karate, and that it is more realistic than free sparring.
