Though Japan is home to a thriving classical music scene, it is wind band, not orchestra, that is commonly found in junior and senior high schools. A quick google search for "Kagoshima orchestra" (in English) pulls up Kagoshima Joho HS's wind orchestra, and they. are. fantastic. Have a listen for yourself.
One of the things that drew me to the JET program and the whole idea of teaching in Japan in the first place is the opportunity to get involved with students in various clubs that span the whole gamut, including sports, English, calligraphy, robotics, newspaper, Japanese archery, and the like. If the school(s) I teach at have an orchestra, great! I'm definitely joining. If they only have wind band, it gets a little tougher.
But regardless of the state of the school music clubs, my first task will be to find a cello.
