Japan Home Shirt 2004/06 (XL) is the blue adidas home design worn by the national side during a successful mid‑2000s period, including victory at the 2004 AFC Asian Cup and qualification for the 2006 FIFA World Cup. This Japan shirt represents the Japan 2004/6 kit era, when the team also appeared at the 2005 FIFA Confederations Cup.
