Gamba Osaka came out on top of a seven-goal thriller on Wednesday while J-League champions Kashima Antlers strolled to another huge rout in the AFC Champions League.
Elsewhere, Adelaide United's campaign was set back by a 0-0 home draw with Changchun Yatai and Uzbekistan's Kuruvchi beat last year's runners-up Sepahan 2-0.
Gamba, held by Chonburi last week, got their campaign back on track with a pulsating 4-3 win away to Korea's Chunnam Dragons.
The J-Leaguers were two down within 29 minutes but fought back through Takahiro Futagawa, Ryuji Bando and Michihiro Yasuda.
Kim Tae-Su slotted a penalty to put the hosts level before Bando turned in Yasuda's cross for the winner 14 minutes from time.
Meanwhile Kashima strolled to a 6-0 rout of Vietnam's Nam Dinh as they continued their free-scoring start to the campaign.
Midfielder Masashi Motoyama and Brazilian striker Marquinhos both scored twice as Kashima, 9-0 winners over Krung Thai Bank last week, stretched their goals tally to 15 and maintained top spot in Group F.
Kashima coach Oswaldo Oliveira already had one eye on the next match against Beijing Guoan, the Antlers' closest rivals.
"It was a good game, but our goal is not only to win this game, but also to advance to the knockout round, so we are going to brace ourselves for our next game," said the Brazilian.
"We will take on the Chinese champions vying for a place in the next round. Hopefully, we can keep up our momentum to win."
In Australia, Adelaide United were held 0-0 at home by Chinese title-holders Changchun Yatai as their ambitions took a knock.
Adelaide were looking to build on last week's 2-0 win over Pohang Steelers, but could not break through although Brazilian midfielder Diego rattled the crossbar in the second half.
"If we want to progress to the next stage we will need to beat Adelaide when we play them at home," said Yatai coach Gao Hongbo.
Asia's premier club competition has been running since 2002. Last year's winners Urawa Reds will join the seven group winners at the quarter-final stage.
