The scope of Kodokan Judo is not defined by the IJF, their commercial motives and the rule sets imposed for their organised Judo championships. Kodokan Judo is defined by its waza, its kata, its history and its educational goals. At this time to ensure the preservation of the totality of judo, the need for prominent judoka and dojo leaders to reject Marius Vizer's efforts to dilute judo for commercial benefit has never been greater. Remember techniques such as kata guruma, kani basami, ashi dori are not banned from judo, they are just against IJF rules - they can, and should still be taught.
