Unfortunately only three short clips. Perhaps not the most exciting footage, as it is amateur-recorded out of hand, but anything with Okano is worthwhile watching. Realize that the man is now close to 70 year old but still moves swiftly like a 30-year old. The third clip is probably the most interesting one. The recordings date from a recent seminar in Japan about 5 months ago (begin June 2013).
