Heading into the game with nine points from their opening three Group H games, the J.League outfit knew victory at the Hitachi Kashiwa Soccer Stadium would see them become the first team to advance to the knockout round.
However, they failed to find a way past a resilient Suwon side and ultimately had to settle for a draw, although they remain firmly on track to make the last 16.
Elsewhere in the group, Guizhou Renhe netted twice in the last six minutes to record a 2-1 home win over Central Coast Mariners - their first victory of the campaign.
Central Coast took the lead through a 41st-minute penalty from Mitchell Duke and looked on course to claim the three points, but the hosts equalised six minutes from time through a fantastic strike from Bosnian international Zlatan Muslimovic.
And just two minutes later, Qu Bo found the back of the net to complete an impressive come-from-behind win for Guizhou.
Over in Group F, Jeonbuk Hyundai Motors produced a stirring fightback to salvage a 2-2 draw at home to Urawa Red Diamonds.
It took Urawa just three minutes to open the scoring when Daisuke Nasu was left unmarked inside the area and headed home a corner, and they doubled their lead just four minutes later after Tsukasa Umekasi pounced on a rebound and lashed the ball into the far corner.
However, Jeonbuk pulled one back six minutes after the break when Eninho scored with a speculative lob, and in the first minute of injury time, Seo Sang-min pounced on a half-clearance and clinically side-footed the ball into the back of the net to earn his side a share of the spoils.
Guangzhou Evergrande extended their lead at the top of the group after recording a 4-1 away win over Muangthong United, whose dreams of progress are now all but over.
Muriqui was the star of the show for the Chinese Super League giants as he netted a quick-fire brace shortly before the break to hand his side a comfortable lead at halftime.
Sarawut Masuk did pull one back for Muangthong with a close-range header in the 52nd minute, but it was not to be as Zheng Zhi restored the visitors' two-goal cushion four minutes later, before Feng Xiaoting wrapped up the three points with a fourth in the 86th minute.
In Group B, Pakhtakor and Lekhwiya played out a real classic in Tashkent but ultimately had to settle for a share of the spoils in a 2-2 draw.
Qatar international Sebastian Soria fired the visitors ahead in the opening minute, but Gulom Uronov popped forward to equalise for Pakhtakor four minutes before the break.
The hosts then edged ahead in the 55th minute when Dame Traore scored an own-goal, Youssef Msakni netted 14 minutes later to earn a point for Lekhwiya.
Al Ettifaq remain in the hunt after an emphatic 4-1 home win over Al Shabab Al Arabi, and they certainly found themselves in a commanding position at the break with a two-goal lead thanks to goals from Saleh Bashir and Yahya Al Shehri.
Brazilian striker Edgar managed to pull one back for the visitors six minutes into the second half, but Al Ettifaq reclaimed their cushion when Bashir netted his second in the 71st minute, before Yousef Salem rounded off the scoring nine minutes later.
Group D's action saw leaders Esteghlal fall to a 1-0 loss at home to Al Hilal, with the only goal of the game coming in the 35th minute when Nawaf Al Abed.
The Iranian giants remain a point clear of their victors and Al Ain, who were also losers on Tuesday as they were beaten 2-1 by Al Rayyan at the Ahmed bin Ali Stadium.
Following a goalless first half, Brazil international Nilmar opened the scoring for the hosts a minute before the hour mark, only for Yousef Ahmad to net an equaliser in the 78th minute.
But with four minutes remaining, Jaralla Al Marri struck the winner to hand Al Rayyan their first win of the campaign.
