A tutorial by Yutaro Matsuura sensei (Renshi 7th Dan)
This is a basic refereeing guide ideal for those ranked 1Kyu to 3Dan. I sometimes feel that it is too late to start educating referees at 3-4Dan. That is why you often see in the Koyokai in-house tournament videos that everyone above 1Kyu is refereeing. This is strictly a guide and should not be your only source of study.
