well i spent high school in three places, first i was the AF school on kadena, then home schooled then i went to the local school which was a lot diffferent from american schools a lot i and one other girl from australia were the only gaijin,,,, fortunately allmost all my friends knew english (most children in japan do) because it wasnt until like the last month i was there that i felt totally confident conversing in japanese
i played volley ball and did some cheerleading but spent most of my time with my best friend being naughty after school and cruising the club scene (when our parents wernt looking)
overall it wasnt a bad experience for me
