In 1967 Kenji Tomiki built a Shodokan hombu dojo in Osaka, Japan, to teach, train and promote his style. Shodokan Aikido is organised as the Japan Aikido Association (JAA) with Tetsuro Nariyama as the chief instructor.
Together, they wrote a key monograph, in Japanese, entitled "Aikido Coursebook" (ISBN 4-469-16288-4), which describes the history of and many technical details about the style of aikido propounded by Tomiki. This book, first published in 1985, was subsequently translated into English by Shodokan Publishing USA under the title, "Aikido: Tradition and the Competitive Edge" (ISBN 978-0964708327).
Competitions take the form of tanto or toshu randori, and also enbu in which pairs (tori and uke) are judged on their kata. Toshu randori is barehanded, and both aikidoka are expected to perform techniques on one another and attempt to resist and counter each other's techniques. The appearance of this form is heavily influenced by judo randori with a few changes designed to enhance the use of aikido technique (for example, one is not allowed to grasp the opponent's keikogi).
In tanto randori, there is a designated attacker (tanto) and a designated defender (toshu). The attacker attempts to stab the defender with a training knife (usually rubber or stuffed) while the defender attempts, with any of seventeen basic aikido techniques, to throw or perform joint-locks on the attacker. Tanto is expected to resist or counter with the first five techniques. In competition, the roles switch, with competitors having the same amount of time with and without the knife. In both these forms of randori, the traditional separation between the performer of technique (tori) and the receiver of technique (uke) no longer exists as either of the participants may throw their opponent.
