Howdy, I study kyudo, though I occasionally wonder why. Historically Japanese archery was primarily about accuracy, distance, penetration, and troop maneuver. Not that much different than English warbows. I think of the 8 basic steps in shooting a yumi as a Japanese Manual of Arms. After the Portuguese introduced firearms to Japan there was a conscious effort to maintain archery in a temple/ court setting. So modern Kyudo is ~ 1/2 martial art and ~ 1/2 etiquette lesson. The perception that hitting isn't important is false, but in kyudo, accuracy needs to be proceded by correct action. And, correct action leading to a hit is considered to show a strong inner spirit! Developement of proper spirit is also part of other Japanese martial arts like the Aikido I also practice.
The modern Yumi is fickle and the ~ 40 inch draw with a floating anchor is not an easy technique to master. So............ yes a great number of practitioners can't hit for beans, and may cover up by saying "it isn't important". But as one of the local Senseis told at a tournament last fall, "that's bullshit!"
That said I find it an enjoyable pursuit. The equipment and style is unique and beautiful and the shooting is graceful. Japanese culture is certainly different than any of the US cultures. Yes I believe there are some distinct cultures here in the US. I think I would have great difficulty living in Japan. Ron
