Japan's 26-man squad for the 2026 World Cup, announced in mid-May by coach Hajime Moriyasu, features strong European-based depth with inclusions like Wataru Endo, Takehiro Tomiyasu, and Ko Itakura despite prior injury concerns, while notable absences include injured attackers Kaoru Mitoma and Takumi Minamino. Trader sentiment for starting XI markets centers on confirmed squad status, recent friendlies showing tactical preferences for a compact midfield anchored by players like Kaishu Sano or Ao Tanaka, and positional battles among attackers such as Takefusa Kubo, Ritsu Doan, and Ayase Ueda. Late developments, including Endo's international retirement due to ongoing injury just before the tournament, have shifted expectations toward alternatives in central areas, while group-stage fixtures against the Netherlands, Sweden, and Tunisia will test lineup stability. Official pre-match announcements, fitness reports from the expanded 48-team format, and Moriyasu's history of rewarding consistent performers remain the primary variables traders monitor.
