Australia's Under-20 football team booked a place at the AFC Under-22 Championship despite suffering a 5-0 drubbing by Japan in their final match of the qualifying tournament in Indonesia.
The Young Socceroos needed a top-two finish in their group to guarantee a berth and previous wins over Indonesia, Macau and Timor Leste and a draw with Singapore were enough for the them to finish second behind Japan in Group E on Sunday.
Japan opened the scoring in the 18th minute when Notsuda Gakuto successfully got his foot onto a cross inside the box.
Japan's second came just after the half hour mark when Yamanaka headed in from a corner.
Watari added Japan's third in additional time of the first half.
The second half was much the same with Japan holding possession and creating chances. Notsuda extended Japan's lead in the 54th minute with substitute Hirota adding a fifth goal 20 minutes later.
"We were beaten by a fitter and stronger Japanese team today," Young Socceroos coach Paul Okon conceded.
"It was a tough match for our players being out of season competing with a Japanese team that are in the middle of the J-League season.
"I am very proud of the players performances to come here and play five hard matches in 10 days when we are in the middle of the off-season in Australia.
"We achieved our goal of qualifying for the AFC under-22 Championship and the team should be proud of this."
