it is really impressive how much control he has over the ball, and how he has managed to stay on top of his game after all those years, considering middle school was back when he was around 10-15, and now he is 26
middle school in japan is 3 years spanning ages 12-15 and he said he played when he was a senior, so presumably until he was 15. (but possibly just till 14, if seniors at his school had to retire from club activities after summer in order to concentrate on studying so they can test into a good high school.)
