Japan's World Cup hopes shaken by referee controversy

Japan's Samurai Blue saw a sock issue in the Sweden match (June 25, Dallas) lead to a temporary dismissal, then suffered a major referee error against Brazil (June 29, Houston). The fallout put group qualification in doubt and closed a path in the knockout stage.

What happened with the socks?

Referee Ivan Barton from El Salvador warned midfielder Keito Nakamura (Stade Rennes) about his short socks at the 8th minute. After Daizen Maeda scored, Barton ordered a sock change again at the 11th minute of the second half, forcing Nakamura off. Japan played with ten men for several minutes, conceding an equaliser to Sweden. Ukrainian outlet Tribuna called the intervention a “disruption of Japan’s rhythm.”

The “century‑defining” error against Brazil

Leading 1‑0, Nakamura cut inside on the left, collided with defender Danilo and the ball crossed the line, but Italian referee Maurizio Mariani ruled a goal‑kick. NHK/BS analyst Keisuke Honda shouted “The referee owes us!” Brazil’s midfielder Casemiro then equalised two plays later, sealing Japan’s exit. VAR covered mistaken corner kicks but not erroneous goal‑kicks, leaving the mistake untouched.

Lost opportunity and future impact

Both decisions stripped Samurai Blue of a realistic group‑top finish. A smoother rhythm against Sweden could have altered the round‑of‑16 opponent. Nakamura later admitted the sock issue caused stress, possibly affecting his Brazil performance. While calls for referee reform grow, Japan is currently riding a 3‑0 win over Bolivia (2025‑11‑18) and a recent form of 3W‑1D‑1L in its last five matches.
