Major League Baseball’s World Series will kick off Wednesday morning Japan time at the Kauffman Stadium in Missouri, with Norichika Aoki of the Kansas City Royals slated to become the 12 Japanese player to appear in the Fall Classic. Japan Real Time takes a look at past Japanese players who have reached baseball’s biggest stage.

Hideki Irabu (New York Yankees)

The first Japanese player to win a World Series championship ring was Hideki Irabu, who was with the New York Yankees in 1998 and 1999 but didn't pitch during the series. Irabu joined the Montreal Expos in 2000 and spent his final year in MLB with the Texas Rangers in 2002.

He returned to Japan and continued his career with the Hanshin Tigers and independent league teams. Irabu died in 2011 in an apparent suicide.

Tsuyoshi Shinjo (San Francisco Giants)

The first Japanese player to appear in a World Series game was San Francisco Giants outfielder Tsuyoshi Shinjo. He had one hit in three at-bats as the designated hitter in Game 1 in 2002. The team lost the series to the Anaheim Angels in seven games. Shinjo returned to Japan in 2004 to play for the Nippon Ham Fighters, where he was a teammate of current Texas Rangers ace Yu Darvish. Shinjo retired from baseball after the 2006 season and now lives in Indonesia where he studies airbrush painting, according to his website.

Hideki Matsui (New York Yankees)

New York Yankees outfielder Hideki Matsui made his World Series debut in 2003, the year he joined the team from Japan. The Yankees lost the series to the Florida Marlins in six games. Matsui returned to the Fall Classic in 2009, and contributed to the team's win over the Philadelphia Phillies as the designated hitter. He had six RBIs in the final game and was named most valuable player. Matsui went on to play for the Angels, the Oakland A’s and the Tampa Bay Rays before retiring after the 2012 season.

In 2004, So Taguchi, then with the St. Louis Cardinals, made his first appearance in the World Series against the Boston Red Sox. The Sox swept the series and became the world champions for the first time since 1918. The Cards and Taguchi returned to the World Series in 2006 and beat the Detroit Tigers in five games. Taguchi also became a world champion in 2008 with the Philadelphia Phillies. He is scheduled to appear as a TV commentator in Japan for Game 2 of this year's World Series.

Following aces Josh Beckett and Curt Schilling, Matsuzaka started Game 3 and allowed two earned runs in 5.1 innings to earn the win. It was the first World Series win by a Japanese pitcher. Matsuzaka played for the New York Mets this season, and went 3-3 with an ERA of 3.89. Okajima is now pitching for the Softbank Hawks, which will play the Japan Series this year beginning Saturday.
