Japan was schooled 3-1 by Iraq as the defending Asian Games champion missed out on booking a spot in the knockout phase on Wednesday.

Two second-half goals by Ali Al Tameemi added to Humam Faraj's opener and gave Iraq its second victory in as many games in Group D and a place in the last 16.

Shoya Nakajima had leveled before halftime for Makoto Teguramori's Under-21s, who were overpowered by a seasoned Under-23 Iraqi side featuring overage players including 2007 Asian Cup MVP Younis Mahmoud.
