Now in the veteran class, Doi has had few opportunities to stake a claim for a regular place in the national team, only making his debut in early 2004 against Malaysia. Doi is renowned as one of the most consistent performers in the J-League, where he currently plies his trade with FC Tokyo, having started out with Kashiwa Reysol. He has a reputation for excelling in penalty shootouts and being an outstanding shot-stopper.
