Zico has lauded Nakamura's improvement since 2002, especially his physical development, stating, "Unquestionably, he has improved a great deal since his move to Serie A. He is the soul of our midfield." Nakamura has flourished under Zico's attacking style and earned his place as the central playmaker. He led Japan to the championship at Asian Cup 2004, where he was named Most Valuable Player, and qualification for the 2006 World Cup Finals. Nakamura also starred for Japan in the 2003 and 2005 Confederations Cup, scoring a total of 4 goals in 5 matches.
