Japan 2018 Home Kit Concept

The national team kit design has gone through several alterations in the past. In the early 1980s, the kit was white with blue trim. The kits worn for the 1992 Asian Cup consisted of white stripes (stylized to form a wing) with red diamonds. During the 1996 Asian Cup and in the 1998 World Cup, the national team kits were blue jerseys with red and white flame designs on the sleeves, and were designed by JFA (with the sponsor alternating each year between Asics, Puma, and Adidas). The 1996 design was reproduced in a special kit used against Syria on 7 June 2017.

Japan uses blue and white rather than red and white due to a superstition. Japan first used blue shirts in the 1930 Far Eastern Championship Games, where a team of the Tokyo Imperial University (whose color is light blue) represented Japan wearing light blue shirts, and then in a 3–2 victory over Sweden in the first game of its maiden major international competition, the 1936 Summer Olympics. When Japan was coached by Kenzo Yokoyama (1988–1992) the kits were red and white, matching the colours of Japan's national flag. After failures at 1990 FIFA World Cup and 1992 Summer Olympics qualifications, the red shirt was scrapped.

Costa Rica 2018 Home Kit Concept

Costa Rica traditionally wears a red jersey with blue shorts and white socks. Their away kit historically was a Juventus-style black and white striped jersey with white shorts and white or black socks, due to these colors being the ones of CS La Libertad, one of the oldest clubs in Costa Rica. However, after 1997, the striped kit was replaced by a white kit. In 2015, Boston-based sportswear company New Balance became the provider of the national team, after taking over for Italian company Lotto. Since 2023, Adidas is the kit provider for the national team.
