Yukuke Kobayashi's second half goal sent Kashiwa Reysol into the quarter-finals of the AFC Champions League after the Japanese side lost 2-1 at home to Korea Republic's Suwon Samsung in their last 16 second leg.
Kashiwa went into the match in a commanding position having won the first leg 3-2 away from home, but their advantage was quickly snuffed out either side of half-time.
Jong Tae-se opened the scoring for the Korean side in the 26th minute, before Ku Ja-ryong gave Suwan the lead in the tie in the 54th minute.
However, their lead was short-lived as Kobayashi netted 12 minutes later to send the former semi-finalists into the last eight after winning on away goals having drawn the tie 4-4.
After losing the first leg and in desperate need of goals, Suwon started the better of the two teams, but were dealt a cruel blow 10 minutes into the match when captain Yeom Ki-hun suffered an injury and had to be replaced by Seo Jung-jin.
While the visitors had the better of the ball, the hosts had the first real chance of the match when Brazilian forward Cristiano's far-post header was kept out by goalkeeper Jung Sung-ryong at his near post.
Suwon kept pressing for a goal and halfway through the first half substitute captain John latched onto a long ball from Yang Sang-min and rifled his shot past Kashiwa goalkeeper Takanori Sugeno.
Kashima nearly leveled matters shortly after when Cristiano's header was cleared off the line by Kwon Chang-hoon before Jung eventually cleared his lines.
After the half-time break, Suwon resumed control of the match and took the lead six minutes before the hour after Kashiwa failed to clear Seo's corner and Ku netted from point blank range.
In desperate need of a goal, Kashiwa resumed control of the match and 12 minutes after going behind, the Japanese outfit was ahead again in the tie after Leandro's shot was only half cleared and Kobayashi's follow up from inside the area found the back of the net.
Suwon attempted to get back in the match in the last 20 minutes but the Kashiwa defense was resolute and snuffed out any more danger.
