Kit of the Day #21: Japan — Samurai Blue Quietly Brilliant

Japan at their eighth World Cup and possibly their best squad ever. The deep blue Adidas kit with the speed-line detailing is a Japan classic done properly. Day 21 of Kit of the Day.

The Asian team most opponents are quietly worried about

Japan beat both Germany and Spain in their Qatar 2022 group. That was not a fluke — the squad has only got better since. They land in Group F with Netherlands, Tunisia and a playoff winner.

The design

Deep blue Adidas home shirt with crisp white and red detailing inspired by speed lines. The pattern subtly references manga panel work without being on-the-nose. One of the design highlights of the 2026 cycle and Adidas’ best non-European release of the year.

Who to watch

Takefusa Kubo creating chances at La Liga level, Kaoru Mitoma still tormenting Premier League full-backs, and Wataru Endo anchoring midfield. Daichi Kamada and Ritsu Doan complete an attacking midfield with proper top-five-league quality across the board.

Why you should care

Japan are one of the form teams in world football, and the design reads strongly on television. If you want a Mitoma name shirt, confirm the final tournament number and exact personalisation terms.
