[slightly off tangent] I think sumo as a professional spectator sport has survived pretty intact over the decades. By this I mean that the particularly Japanese cultural forces, rituals, and lifestyle, permeate sumo very deeply, even during the reign of non-Japanese yokozuna. As highly competitive as it is, you do not see any hooting and hollering by the wrestlers and no pumping of fists after a victory. Their rei at the beginning and end of each match seem very sincere to me. I know that sumo is not in the running to be the next olympic sport, but I thought it might be a good example of how a "professional spectator sport" can still retain the reigi that we believe would be lost in kendo should it become primarily sport-oriented. -michael
