1986 MLB Japan All-Star Series

The 1986 MLB Japan All-Star Series, also known as the Super Major Series, was the first edition of the MLB Japan All-Star Series, a best-of-seven series between the all-star teams from Major League Baseball (MLB) and Nippon Professional Baseball (NPB), then-called All-Japan.

MLB won the series by 6–1–0 and Tony Peña was named MVP. The games were played in November 1986 after 19 months of negotiations between MLB and NPB; most of the MLB roster was drawn from the selections for the 1986 MLB All-Star Game, while the NPB chose Japanese players rather than Americans who played for Japanese teams.
