With their lightning quick passing and slick combination play, the Japanese may well have a grip on the future of the game.

The physical, sweeping game of the Americans stands in sharp contrast with the close, possession-oriented game of Japan, turning tomorrow’s match into an intriguing clash of styles.

The Americans beat Japan in two pre-World Cup exhibitions, but that will count for little in the final.

“They’re a different team here in the World Cup,’’ said US captain Christie Rampone. “It brings a different level.’’

The accolades for Japan have been coming in from all angles, comparing its style with that of Barcelona and Brazil’s “beautiful game.’’

Japan has sought to develop that flair for years, but only this time do they have the confidence to execute it at the highest level. Japan coach Norio Sasaki said his team was ready to reach the Olympic semifinals three years ago in Beijing and “this time we said, let’s go to the final.’’

The cup itself is within reach, he said.

“It’s definitely not impossible,’’ Sasaki said. “It is a once in a lifetime chance to win this and beat the No. 1 team in the world.’’

Japan’s breakthrough victory came in the quarterfinals last weekend when it beat host Germany, the two-time defending champion.

Even if tomorrow is Japan’s first final in the record books, Sasaki said his players already have one under the belt - against Germany.

“This was almost like playing the final in terms of pressure, attitude, and expectations,’’ Sasaki said of the earlier game. “The actual final will be a very similar situation.’’

That same weekend the United States rallied in an intense match against Brazil with a penalty-shootout win. It created a groundswell of support across America.

“Obviously, coming from behind against Brazil is historic,’’ said Abby Wambach, who scored in the last minute of extra time, tying it at 2 and forcing a shootout. “It’s one of those moments that may never happen again.

“I want it to be life-changing at the end of the road. Because right now, I’m still very much involved in this and I’m not trying to think anything other than Sunday and winning.’’
