Japan recorded their first FIFA World Cup? win on foreign soil after Keisuke Honda's 39th-minute strike proved enough to down Cameroon at the Free State Stadium.

Honda's decisive contribution was handsome reward for Japan coach Takeshi Okada's gamble to deploy the CSKA Moscow midfielder in a central attacking role in an attempt to remedy his team's lack of goals. The Japanese, without a clean sheet in their warm-up matches, then frustrated Cameroon at the other end, surviving a late scare when the woodwork denied Stephane Mbia.

With the victory – their first in an opening game – Japan joined the Netherlands on three points at the top of Group E, while Cameroon's second match against Denmark, the day's other losers, assumes do-or-die dimensions.

The match began with a surprise in the Cameroon starting lineup with Mbia asked to fill in at right-back, his usual holding role in the middle going to Joel Matip. It was Cameroon's left-back Benoit Assou who was busier, though, with most of Japan's forward movement coming down their right side through Daisuke Matsui.

The Grenoble-based midfielder was the creator of Honda's winning goal when, after several crosses that came to nothing, he finally got his angles right and swung over a high ball which evaded the Cameroon defenders and fell at the far post to Honda. The CSKA Moscow man needed one touch to control the ball before steering it coolly past Hamidou Souleymanou.
