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
