Among the Asian countries, South Korea, Japan, Saudi Arabia, these three teams qualified to play the World Cup. In the last World Cup, Qatar was the host nation, which did not require them to qualify for the World Cup, but they qualified to play in the World Cup as the host nation. There is still a lot of speculation about the final teams for the 2026 World Cup. It is also possible that the teams that we have seen qualify for the main stage in the 2022 World Cup may not qualify for the main stage of the 2026 World Cup.
Maybe apart from these teams, some other teams have a good chance to qualify for the 2026 FIFA World Cup. Iran, South Korea and Japan are currently performing best in the FIFA World Cup Asian Qualifiers matches. These teams are all at the top of the points table. Although Saudi Arabia and Australia performed poorly in the qualifier matches, they have been playing in the FIFA World Cup for a long time, maybe they will qualify for the 2026 World Cup as well.
But there is a good chance for Japan to qualify for 2026 World Cup and if Japan can qualify for the main stage of 2026 World Cup then I believe they will do well there.
The performance of all Japanese players in the Asian Qualifier matches was outstanding, although most of the players in their team were young but they gave their best performance for the team. Japan have won five out of six matches in the Asian qualifiers, so they may have a good chance of qualifying for the FIFA World Cup.
