Matsui held a press conference on Wednesday confirming that Jeter would be participating in the event that will benefit victims of the March 2011 earthquake and tsunami. The pair will host a baseball clinic and also face-off in a home run derby on March 21 at the Tokyo Dome.
"(Derek) will make an enormous contribution to this event," Matsui said. "He is a tremendous human being and was a great teammate and I'm sure the kids will be thrilled to see someone of his stature."
Matsui came over from Japan in 2003 to sign with the Yankees and he was the World Series MVP in 2009. He went on to have stints with the Angels, Athletics and Rays before retiring in November 2012. In 10 major league seasons, he had a .282 batting average, 175 home runs and 760 RBI.
Jeter retired following a 20-year career with the Yankees, winning the World Series five times.
