Japan turned on the style in Monterrey, a 4–0 dismantling of Tunisia that confirmed the Samurai Blue as serious contenders to win the tournament's highest-scoring group.

Japan's 4-0 win actually flattered them relative to the underlying numbers: an xG of just 2.13 produced four goals, meaning they finished at roughly double their expected output, driven by Daichi Kamada's 4th-minute opener and Ayase Ueda's clinical brace. Tunisia were utterly toothless, mustering only 2 shots for 0.05 xG and failing to register a single shot on target despite seeing 40% of the ball, so their possession brought no penetration whatsoever. With 5 shots on target converted into 4 goals, Japan were ruthlessly efficient while Zion Suzuki was barely tested at the other end. The discipline lines (no cards either way) and Tunisia conceding 15 fouls underline a one-sided, low-aggression rout that eliminated Hervé Renard's side.
