Like it was mentioned earlier, if you're affiliated with the military (dependent, etc), there's options for you. I don't know what branch or what base/post you are stationed, what I do know is that Yokota AB and Kadena AB have aero clubs. You don't necessarily have to wait until you come back stateside, you can start taking lessons and knock out some classes. I would suggest that you look into what type of support facilities are available at your place. You never know...
