Kyudo refers to traditional Japanese archery, which is unique from other cultures by virtue of its tall, asymmetrical bow (the "yumi"), and the ethos it suffuses into the art. Hitting the target is, of course, the purpose of archery. In kyudo, however, the technique used to hit the target, your attitude in both success and failure, and the way you interact with the others around you are just as important as where your arrow lands.

Beginners start with the basic principles of shooting, then slowly incorporate the basic body movements, group shooting procedures, the terminology, underlying philosophy, and if desired, may prepare to test for rank. Kyudo has a dan system (much like belt tests in other martial arts, minus the belts) which is a rewarding path to follow, but not required. The Iowa group will take you across North America and Japan, if you so wish.
Some people join kyudo purely for enjoyment and/or the people who practice it, and this is valid. Others may take interest in the older schools of kyudo, which place greater emphasis on the martial roots of the art, horseback archery, meditation or etiquette. The Iowa group places more emphasis on contemporary kyudo, but can be an introduction to the other schools.
Kyudo is one of the few martial arts where neither age, gender, nor physical strength confer any special advantage or disadvantage. Even disability does not necessarily preclude someone from kyudo, except for chronic shoulder or arm injuries. There are some themes, though, amongst those who practice Japanese archery the longest:
Perfectionists tend to do very well in kyudo. There is an extraordinary amount of detail involved in shooting and the group performances.
Japanophiles often get a lot of enjoyment, both for the exposure to Japanese culture, and the concentration of people who like the same things.
People who come from other martial arts, dancers, gymnasts and others with a high degree of body awareness have an easier time up front.
Musicians have a big advantage later on due to their proficiency with tempo and unspoken coordination.
Anyone with grit. Some people have a natural talent for kyudo, and do very well initially. Everyone, without exception, eventually hits a wall in their progress, however. Usually it's the people who struggle at first, but are willing to work at it, despite the frustration, who do best in the long run.
