I happened upon the video below while surfing on YouTube one day.
Kyuzo Mifune (who was a 10th Dan at the time the video was taken apparently) fights a series of 7 much younger opponents ranked between 6th and 8th dan.
In each case he allows the opponent to try to throw him at least once before he finished the bout.
The way he avoids being thrown is so brilliant that it made me laugh-out-loud!
The man was a genius.
Apparently the video was made in 1948 and Mifune was 73 years old (although I find it impossible to reconcile these two facts with the report on Wikipedia that he was born in 1883). But his age certainly makes his performance all the more amazing.
The full video is available here.
