SAN FRANCISCO -- For those who haven't played there before, AT&T Park can be a challenge, to say the least. There's the corner in deep right-center field's "triples alley," the famous arcade, over which balls fly into McCovey Cove, and of course there's the fact that the ballpark is on the San Francisco Bay, with its winds and chill.

For Japan manager Koji Yamamoto, taking a little bit of time to get acclimated with the dimensions of the unique ballpark is all that was needed, not anything more complicated than that.

"Nothing special, I haven't done anything," Yamamoto said when asked about preparations. "Of course, outfielders are getting coaching ... but, of course, it's going to be harder to get the home runs, so we will just make sure we catch the balls properly."

Japan's starting outfielders for Sunday's semifinal included Sho Nakata in left, Yoshio Itoi in center and Seiichi Uchikawa in right.

Without MLB star, Japan thrives on team concept

SAN FRANCISCO -- No Ichiro. No Dice-K, no Yu Darvish. No Major Leaguers at all on Japan's World Baseball Classic roster, not even one.

No problem for Japan, apparently. Here it is again in the Classic championship round, taking on Puerto Rico in a semifinal Sunday for the right to advance to Tuesday night's final at AT&T Park, a possible third title in sight.

To Japan manager Koji Yamamoto, this team full of Nippon Professional Baseball League players might not have the same star power Americans became accustomed to in the previous two editions of the Classic, but this team has very much the same team concept -- which, more than anything, led to the team's success before.

"I think our strength comes from the same thing, just teamwork, everybody being one in their heart," Yamamoto said. "And that's why we were able to win, and I think we have the same atmosphere on the team."

Ichiro Suzuki told Japanese officials in November that he would not play in this year's tournament, joining Darvish and Brewers leadoff hitter Norichika Aoki. Daisuke Matsusaka signed with the Boston Red Sox in 2007 after his first Classic MVP performance and then earned MVP honors again in 2009.

The Japanese team does have one former Major Leaguer on the roster in infielder Kazuo Matsui, who signed with the Mets in 2004 and also played for the Rockies and Astros through 2010.

Japan has nine veterans from the 2009 Classic championship squad and one player who has participated in three Classics now -- left-hander Toshiya Sugiuchi.
