Nagoya reach summit, Nakamura sinks Shimizu
With the scores level at 1-1, Tamada fired home from 20 yards out in the 79th minute, and netted another from a pass from Australian international Joshua Kennedy four minutes later.
Former Urawa defender Marcus Tulio Tanaka had started the scoring against his old club with a 54th minute header, but their lead was cancelled out by Tomoya Ugajin 11 minutes later.
Nagoya are now two points clear of previous leaders Shimizu S-Pulse and three points ahead of defending champions Kashima Antlers.
"I couldn't score in our previous games. I finally scored today. I'm glad that we won this away game," said Nakamura, who played only one game as a substitute in the FIFA World Cup™ in South Africa.
Kashima were held to a 1-1 draw by FC Tokyo after Shinzo Koroki's opener was cancelled out by an equaliser from defender Yasuyuki Konno four minutes from time.
