Gamba Osaka surged past AFC Champions League qualification play-off opponents Johor Darul Ta’zim 3-0 on Tuesday.
Goals from Ademilson and Shun Nagasawa before the half-hour mark set Kenta Hasegawa’s men on their way, with both goals coming from inside the box.
Genta Miura put the icing on the cake with Gamba’s third goal of the day as the 2008 ACL champions booked their place in the upcoming group stages.
They have been drawn in Group H alongside Adelaide United of Australia, China’s Jiangsu Suning and Jeju United from South Korea.
