Keisuke Honda believes that more of his Japan team-mates need to represent the world's top sides.
A 2-1 loss to Mexico ended the Samurai Blue's Confederations Cup campaign with three consecutive losses, two goals from Chicharito enough for La Verde to seal the win, the Mexicans holding on despite Shinji Okazaki's late strike.
And the CSKA Moscow star argues that it is imperative for his compatriots to target roles in big clubs if the national side are to improve amid speculation mounting that he may be close to signing for AC Milan.
"Italy only had two days off and they beat us, so you need that sort of mental strength to win in any condition," Honda told reporters after the game.
"The level of the club you play for influences that strength, so it's very important to play at higher-level clubs in stronger leagues.
"It's a very difficult problem [to improve Japan's overall play] but there are countries with smaller players who manage to defend well, so, if we can improve our abilities, I think we can do the same."
Honda, who has decided not to renew his contract with his current employers, alerting the likes of the Rossoneri, has enjoyed a successful time in Russia's top flight of late, with his side winning the league and cup double last season.
The former VVV-Venlo man stressed that Japan must look to learn from their Confederations Cup campaign, stating that his team lost too many of the individual battles on the pitch.
"If there's a difference between us and Mexico, it's that, when the game slowed down, you could see the difference in individual strength," he continued.
"We showed plenty of evidence that we can play in an organised way but, at the very end, when we have a chance to decide the match, we weren't able to create the big plays.
"Especially when Mexico were slow to drop back, we couldn't press forward with three or four players."
