Shodokan

Shodokan Aikido addresses the issue by practising in a competitive format.

Shodokan Aikido, however, was controversial, since it introduced a unique rule-based competition that some felt was contrary to the spirit of aikido.

These students included Kenji Tomiki (who founded the Shodokan Aikido sometimes called Tomiki-ryū), Noriaki Inoue (who founded Shin'ei Taidō), Minoru Mochizuki (who founded Yoseikan Budo ), Gozo Shioda (who founded Yoshinkan Aikido ).
