Japan

A landmark shirt in Japanese football history, worn during the 2002 FIFA World Cup — co-hosted with South Korea — as the Samurai Blue reached the Round of 16 for the first time. Manufactured by Adidas, the shirt features Japan's iconic deep royal blue with the three stripes running across the shoulders in silver-white, red piping trim along the chest panels and sleeves, and the JFA crest prominently displayed alongside the "JAPAN" wordmark. The textured mesh fabric was typical of Adidas's early 2000s construction, balancing performance with a clean, striking aesthetic that reflected the growing profile of Japanese football on the world stage.
