The Japanese opened the scoring after just 37 seconds, with a Goto free-kick stunning the Senegalese. Tabata doubled his side's advantage late in the first period, before Matsuo and Akaguma stretched the advantage further still after the first break.
As a result, Japan head through to the quarter-finals from Group A in second place behind hosts Portugal, and they will face Group B winners Italy in the quarter-finals on Thursday.
