Before 1950, the original [[Japanese Baseball League]] had been a single-table league of franchises. After it was reorganized into the [[Nippon Professional Baseball]] (NPB) system, a series of playoffs ensued between the champions of the [[Central League]] and [[Pacific League]].

Before the playoff system was developed in both professional leagues, the Pacific League had applied a playoff system on two occasions. The first was between 1973 and 1982, when a split-season was applied with a 5-game playoff between the winning teams from both halves of season (unless a team won both of the halves so that they did not need to play such a game). The second time was between 2004 and 2006, when the top three teams played a two-staged stepladder knockout (3 games in the first stage and 5 games in the second stage) to decide the League Champion (and the team playing in the [[Japan Series]]). After this system was applied, the [[Seibu Lions]] (now Saitama Seibu Lions), [[Chiba Lotte Marines]] and [[Hokkaido Nippon Ham Fighters]], which claimed the Pacific League Championship under this system, were all able to clinch the following Japan Series in that season. The success of such a playoff system convinced the Central League to consider a similar approach. In 2007, a new playoff system, named the "[[Climax Series]]", was introduced to both professional leagues in NPB to decide the teams that would compete for the Japan Series. The Climax Series basically applied the rule of the playoff system in the Pacific League, with one important change: each League championship is awarded to the team finishing the regular season at the top of their respective league, regardless of their fate in the playoffs. This means that the two League Champions are not guaranteed to make the Japan Series. The [[Chunichi Dragons]] took advantage of this in the first Climax Series season, finishing second in the regular season but sweeping the [[Hanshin Tigers]] and the League Champion [[Yomiuri Giants]] in the Central League to win a place in the Japan Series; they subsequently defeated the Hokkaido Nippon Ham Fighters to claim their first Japan Series in 52 years.

In 2008, the format of Climax Series will have a slight change, in which the second stage will be played over a maximum of six games, with the League Champion starting with an automatic one game advantage.
