The Seattle Mariners, who signed free agent Japanese righthander Hisashi Iwakuma (he-sash-ee e-wah-kuma) less than a week ago, Wednesday added Japanese infielder and eight-time All-Star Munenori Kawasaki to a minor league contract with an invite to spring training.

It’s the second minor league contract to which the Mariners have agreed in two days. The club Tuesday signed right-handed pitcher Aaron Heilman, a veteran of nine major league seasons with the New York Mets (2003-2008), Chicago Cubs (2009) and Arizona Diamondbacks (2010-2011) — and, briefly, a Mariner.

For a little more than a month prior to the 2009 season, Heilman was on Seattle’s roster after being acquired from the Mets as part of a 12-player, three-team trade in exchange for RHP J.J. Putz, RHP Sean Green and OF Jeremy Reed on Dec. 11, 2008. But Heilman was traded to the Cubs Jan. 28, 2009 in exchange for LHP Garrett Olson and INF Ronny Cedeño.

Kawasaki, 30, is an eight-time All-Star (2004-11) and a two-time Golden Glove winner with Fukuoka in the Japan Pacific League. In 11 seasons in Japan, he hit .294 (1343×4573) with 631 runs scored, 65 triples and 262 stolen bases in 1,145 games.

Last season, Kawasaki batted .267 (161×603) in 144 games and helped lead the Softbank Hawks to their first Japan Series championship in eight years. He has 20 or more steals in eight of the past nine seasons, including a league-leading 42 in 2004.

“Being able to add a player with the resume that Kawasaki possesses is very good news for the Mariners,” said general manager Jack Zduriencik. “We are looking forward to having him compete for a major league position in spring training. He is a high-energy player with a record of success in Japan.”

Kawasaki was also a two-time member of Japan’s gold-medal-winning World Baseball Classic squad, and was the starting shortstop for Japan in the 2008 Beijing Olympics.
