Pacy full-back who has a reputation for fair play and not causing too many problems for referees. A useful man-marker who can also play in central defence, Tsuboi only joined the professional ranks four years ago but quickly established himself as a first-team regular with Urawa Reds, his only club to date. He made his international debut in November 2003 against Paraguay and has racked up more than 30 caps to date, despite injury halting his progress on a couple of occasions.
