Daisuke Matsuzaka began preparing for his 2008 season Sunday with a five-hour workout at his former team?s Seibu Lions stadium in Tokorozawa, Japan.

Matsuzaka told reporters he planned to work out in Japan for about a month and that unlike last year, he would not be conducting his January workouts in Southern California. A year ago, Matsuzaka spent much of this month throwing and exercising near his agent Scott Boras? home office in Newport Beach, Calif., before reporting to Fort Myers for his first season with the Red Sox.
