World Cup: Japan toil to beat Cyprus in warm-up game

Japan, who looked heavy-legged after a punishing training camp last week, face Ivory Coast in their opening game at the World Cup in Brazil on June 14.

Right-back Uchida broke the deadlock in Saitama when he stabbed home the loose ball after Shinji Kagawa's close-range effort had been blocked, registering only his second goal in 66 internationals.

"It was nice to score coming back from injury," said Uchida, who celebrated his strike by sprinting to the touchline to hug Japan coach Alberto Zaccheroni.

"I didn't know if I would be fit in time," added Uchida, returning from a lengthy spell out with a thigh problem. "I really wanted to get on the scoresheet tonight."

With Cyprus defending resolutely, a clever step-over from Kagawa brought the crowd of 58,000 to their feet, only for Keisuke Honda to waste Japan's only other chance of a scrappy first half.

Kagawa and captain Makoto Hasebe, himself working his way back to fitness after a knee problem, went close as Japan showed more urgency after the break.

But ultimately the home side lacked the cutting edge Zaccheroni had demanded before the match.

"We weren't as sharp as we can be but the players kept probing," said the Italian, who has stubbornly refused to make any World Cup predictions.

"I'm not the sort of person to make promises about results. But I do demand the players put in the effort required to get results. We will be 100 percent for June 14."

Japan, who also play Greece and Colombia in Group C, have further friendlies against Costa Rica on June 2 and Zambia on June 6 in Tampa before flying to Brazil.

The 'Blue Samurai' reached the last 16 at the 2010 World Cup in South Africa.
