Japan, which had been beaten up in a physical matchup with Cote d'Ivoire in a 2-1 opening loss, once again had to deal with a bigger, stronger and much taller opponent.

Coach Japan coach Alberto Zaccheroni dropped Kagawa from the starting lineup in surprise move, putting veteran striker Okubo up front with Europe-based star Keisuke Honda.

Okubo had one of Japan's best chances to score in the first half but sent his header over the crossbar in the 33rd minute

Zaccheroni was frustrated Japan didn't use its speed to exploit the spaces left by Greece being short a player. A win over Colombia won't guarantee Japans moves on to the next round. If Cote d'Ivoire beats Greece, Japan will go home.

"We played too slowly," Zaccheroni said. "This is not a positive result. We absolutely needed to win."
