Japan's national sport, sumo, has attracted much international interest. Part of its appeal are its esoteric customs including the wrestlers' traditional topknots, of which there are several styles dating back centuries. The men who do the sumo wrestler's hair are called "tokoyama". This program features Mitsuo Sato who works at one of the sport's most prestigious stables; it is a stimulating look at a traditional art that requires much skill and experience.
