Okazaki Tomoya (岡崎朋也) is the main character of Clannad. He was an ordinary third year high school student (class 3-D), who wasn't involved in any clubs. He was often late for school. His best (and only) friend was Sunohara Youhei , and he spent a lot of time in Youhei's dorm room.

Tomoya entered the high school on a basketball scholarship. But he injured his right shoulder in a fight with his father, so he couldn't play basketball any more. He had no desire to join any other clubs.
