2026– date –

Yukinari Sugawara gives Japan more than depth at right-back for the 2026 World Cup. His Werder Bremen numbers, crossing output, and positional flexibility could make him a key tactical option on the right.

Ayumu Seko is unlikely to enter Japan’s 2026 World Cup squad as a locked-in starter, but his value may be larger than that. After a first Ligue 1 season at Le Havre that included regular minutes at center-back and defensive midfield, he gives Hajime Moriyasu a rare tactical safety valve inside a 26-man squad.

Hiroki Ito's value to Japan goes beyond defending: his left foot, positional flexibility, and ability to reshape the back line could make him a key World Cup piece if he stays healthy.

Takehiro Tomiyasu’s biggest value to Japan is not simple depth. If fit for the 2026 World Cup, he gives the back line stronger duels, cleaner buildup, and the flexibility to shift across multiple defensive roles without losing shape.

Ko Itakura may be one of Japan’s most important players at the 2026 World Cup because he offers both defensive strength and the ability to move the team forward from the back.

Tsuyoshi Watanabe’s strongest case for Japan at the 2026 World Cup is not flashy buildup play, but dependable center-back work: duels, aerial defending, set pieces and lineup flexibility built on a full starting season at Feyenoord.

Yuto Nagatomo's place in Japan's 2026 World Cup squad looks less like a ceremonial call-up and more like a practical bet on depth, stability, and tournament experience.

Shogo Taniguchi's likely role in Japan's 2026 World Cup squad is not just veteran depth. His biggest value is organizing the back line, especially in the middle of a back three, where calm positioning and game management can shape Japan's tournament defense.

Zion Suzuki’s case for Japan’s 2026 World Cup squad is built on more than reflex saves. His Serie A season at Parma shows why he could give Japan greater stability, cleaner build-up, and a realistic starting option in goal.

Keisuke Osako’s place in Japan’s 2026 World Cup squad is backed by more than club status. His 2025 numbers, distribution, and reliability explain why he matters in Hajime Moriyasu’s goalkeeper group.
