Honestly, I don't want to be too pessimistic, but any of these national teams (
Kyrgyzstan,
Palestine,
Bahrain and
China ) that qualify will only be able to celebrate for qualifying and will not win the World Cup, that is, they are only dreaming of guaranteeing participation in the World Cup, unfortunately the national teams from Asia have no chance of winning the World Cup, in America there is only Brazil and Argentina, while in Europe there are many national teams such as France, Italy, Spain and Germany.

Japanese football has been growing a lot in the last 30 years. I remember that back in 1998, during the World Cup hosted in France, Japan lost all three games of the group stage (they even lost against Jamaica); four years later they won their group and they lost against a great Turkey team. And since that won they also won a bunch of Asian Cups and they always qualified for the World Cup and now the majority of the national team players play abroad, mainly in Europe. Japan has a plan to increase their level, and they are following it.
