Japan may be the most underrated team in this World Cup.

Japan 4:0 Tunisia.
Even more astonishing is.
Kaoru Mitoma, Takefusa Kubo, and Ao Ete partially rested.
They still played an almost crushing game.
Japan's current problem is no longer whether they can qualify.
But:
Will they become the Asian team most reluctant to face in the knockout stage?
Japan's advantages:
✅ High pressing ability
✅ Tactical execution
✅ Running coverage
✅ Improved substitute depth
Japan's weaknesses:
❌ Aerial duels
❌ Central defender physical confrontation
❌ Still at a disadvantage against top physical teams like France and England
My judgment:
Japan already has the strength to reach the quarterfinals.
There is even a chance to challenge the semifinals.
