Although some of the content may be a bit outdated, this is a good general reference for kendo shiai and shinpan procedures. The clip is a bit blurry – the original VHS tape quality wasn’t that great – no HD back in the day.
An outstanding text reference for shiai and judging protocols, outside the AJKF guide book, is The First Steps to Becoming a Referee by Terry Holt (http://www.mumeishikendo.com.au/docs/holt_first+steps+to+becoming+a+referee.pdf). This wonderfully illustrated document is well written and is formatted for easy discovery of information.
