The Yomiuri Giants won the Central League pennant last season but failed to reach the Japan Series.
Offseason addition Alex Ramirez helped make sure they got things right this time around.
Ramirez hit a two-run homer in the eighth inning to drive in the go-ahead runs as the CL Champion Giants defeated the Chunichi Dragons 6-2 to punch their ticket to the Japan Series in front of 46,797 fans on Saturday night at Tokyo Dome.
