They were the heroes of our qualifying game against Australia. They haven't been chosen this time, and if things continue the way they are, there is a chance that they won't be chosen for the World Cup".[37] In May, Asano was named in Japan's preliminary squad for the World Cup, but failed to make the final cut.[38]
In his first match in the 2022 World Cup, Asano scored a goal in the 83rd minute to give Japan an upset victory over Germany.[39]
