Nagoya Grampus managed a 2-1 win over Omiya Ardija to keep their eight-point lead over the rest of the J-League.
Igor Burzanovic and Takahiro Masukawa did the damage for the home side who maintained their break as second-placed Kashima Antlers also won 2-1 after coming from behind at Kawasaki Frontale.
With four matches left in the 2010 season, Nagoya are in a strong position to take out the title, especially as they take on bottom-placed Shonan Bellmare next weekend.
