Goals from Keisuke Honda and Shinji Kagawa were enough for Japan to see off Jordan and seal top spot in Group D of the Asian Cup.
Honda gave Japan the lead in the first half, tapping in at the back post after Jordan goalkeeper and captain Amer Shafi could only parry Shinji Okazaki's drive across goal.
It was Honda's third goal of the tournament after a penalty in each of Japan's previous wins - a 4-0 triumph over debutants Palestine and a 1-0 victory against Iraq.
The Samurai Blue wasted numerous opportunities before adding a second in the 82nd minute through Kagawa.
But although they topped Group D with nine points and three clean sheets, the performance in Melbourne was not up to the level that many expect of Javier Aguirre's side in Australia.
In the 10th minute, Jordan were given a clear indication of Japan's threat when Takashi Inui hit the back of the net after a cut-back from Kagawa, but the Borussia Dortmund midfielder was just offside.
Ray Wilkins' Jordan were keen to disrupt Japan's flow and their physical intentions resulted in an early yellow card for Mohammad Mustafa, who raked his studs down Makoto Hasebe's shin.
Mustafa's lunge was not the only poor tackle by Jordan and the Middle Eastern side could do little when Honda opened the scoring in the 24th minute.
Okazaki struck a firm drive across goal which goalkeeper Shafi could only parry into the path of Honda, who gleefully tapped home.
Aguirre's men were suddenly flying with Shafi forced to punch a dangerous cross away before Okazaki hit the side netting, but Jordan held on to trail by only one goal at the break.
The striker was at the heart of all of his side's best work and could have made it 2-0 immediately after the break, but Shafi smothered the ball at the striker's feet with the Mainz forward surprisingly yellow carded for the clash.
Wilkins had made two substitutions at half-time with Ahmad Hayel and Monther Abu Amara replacing Yousef Al Rawashdeh and Abdallah Deeb, and they seemed to inspire his team.
Hayel, in particular, looked lively as Jordan kept Japan pinned back for prolonged periods, but Aguirre's side still looked most likely to score with Yasuhito Endo shooting just over the bar, Honda having another goal ruled out for offside and Maya Yoshida heading wide.
Japan finally got their second goal with eight minutes remaining, with Yoshinori Muto teeing up Kagawa, whose side-footed effort was parried into the net by Shafi.
