Tomoya is a 17 year old high school student who resents his town because of all the bad memories he experienced while living in it. Rather than falling into depression though he becomes a sarcastic delinquent. He is a childhood friend of Kotomi Ichinose and is best friends with Youhei Sunohara. As he progresses through high school, he meets many new friends, such as Kyou, Ryou, Tomoyo, Fuko, and of course Nagisa.

Though Tomoya is a delinquent he does not go around looking for fights. However when he does get into a brawl he is shown as a very tough fighter, able to take his opponent's blows and still manage to counter-attack fiercely.

Ever since his mother, Atsuko, died in a car accident when he was young, Tomoya has been living with his father, Naoyuki Okazaki, with whom he argues with constantly. Tomoya was injured during a fight with his father three years ago; since then, he could no longer lift his right arm higher than his shoulder. After that incident Tomoya's relationship with his father has been very distant.
