As I mentioned at training yesterday, the 8th dan championships are probably the real pinnacle of Kendo competition in Japan. Watch particularly the opening bow to shomen as well as to each other. This is because it is the final. This is a good example of the bowing rituals or reigi saho for competition. You can also find other matches in the Youtube sidebar, since this is from the All Japan Kendo Renmei's channel, including some super-slow clips of winning points.
