Yokohama F. Marinos preserved their 100 percent record in the J. League with a last-gasp 2-1 victory over Kawasaki Frontale on Saturday.
Yasuhiro Higuchi's men hit the front on the stroke of half-time courtesy of Seitaro Tomisawa however Yusuke Tanaka levelled proceedings in the 65th minute.
The match seemed destined for a draw before substitute Jin Hanato netted a 90th-minute winner, much to the delight of the Yokohama locals at Nissan Stadium.
Yokohama are now six-from-six this season, having scored a league-high 19 goals, while Kawasaki are still looking for their first in 2013.
Omiya Ardija also maintained their unbeaten start, overcoming Cerezo Osaka 2-1 to move up to second in the standings.
Less than a minute had ticked over before Shin Kanazawa gave the visitors a surprise lead but Yoichiro Kakitani ensured scores were level at the break.
Omiya restored their lead five minutes from time, when Slovenian attacker Zlatan Ljubijankic bagged his third goal in as many games.
Elsewhere on Saturday, Nagoya Grampus improved to fourth after accounting for Albirex Niigata 2-0 at Toyota Stadium.
First-half goals from Keiji Tamada and Teruki Tanaka were enough to hand the home side all three points.
Kashima Antlers survived a scare to fend off cellar-dwellers Oita Trinita 3-2.
Oita had taken a 25th-minute lead but Gaku Shibasaki and Takuya Nozawa put the visitors ahead before the hour-mark.
Yasuhito Morishima looked to have earned a point for the strugglers before Yuya Osako secured maximum points for fifth-placed Kashima.
In other results, seventh-placed Ventforet Kofu defeated Kashiwa Reysol 3-1, Shimizu S-Pulse edged lowly Jubilo Iwata 1-0, while Tokyo suffered a 2-1 loss at Vegalta Sendai.
