The event featured a roster of MLB All-Stars competing against Japan's best in front of enthusiastic crowds across four cities. These games served both as competitive matchups and cultural exchanges, highlighting the growing international influence of baseball.

• Seven games were played between November 1 and November 9, 2006, across multiple Japanese cities, including Tokyo and Fuku游戏副本, making it one of the most extensive MLB tours in Asia.
• The MLB All-Stars roster included marquee names such as Alex Rodriguez, Derek Jeter, and Jake Peavy, showcasing a blend of power hitters and elite pitchers.
