The Japan Series ( , officially the Japan Championship Series, ), also the Nippon Series, is the annual championship series in Nippon Professional Baseball, the top baseball league in Japan. It is a best-of-seven series between the winning clubs of the league's two circuits, the Central League and the Pacific League, and is played in October or November. The first team to win four games is the overall winner and is declared each year. The Japan Series uses a 2âÂÂ3âÂÂ2 format, with the latter four games in theory if additional games are needed following ties.
The home team for games 1, 2 and eventually 6 and 7, alternates between the two leagues with the Pacific League having the advantage on the years ending with an odd number and the Central League on the years ending with an even number. Designated hitters are used if the team from the Pacific League hosts the game. There is a 40-man postseason roster limit, and the rule on drawn games is changed to 12 innings, since 2018. If the series is tied after the seventh game, a Game 8 will be held with the same team hosting Games 6 and 7 hosting this game. Only once has a Game 8 been played in Japan Series history, where the Seibu Lions defeated the Hiroshima Toyo Carp in 1986. In the event that Game 8 does not decide the series, the next game would be played at the stadium that hosted Games 3 through 5 after a day of rest, and games will continue until one team wins four games.
Every current team in the NPB has won the Japan Series at least once. The team with the most championships is the Yomiuri Giants, who have won the Japan Series twenty-two times. In 2004, the Pacific League instituted a three-team stepladder playoff format to determine the league champion, while the Central League champion had a long wait before the Japan Series. During this time, the Pacific League won four consecutive Series from 2003 to 2006. Starting with the 2007 postseason, both leagues adopted the Climax Series to determine their champions. The Climax Series involves the top three finishers in each league, though the format gives a significant advantage to the team with the best record in each league.
On November 6, 2010, the Chunichi Dragons and Chiba Lotte Marines played the longest game in Japan Series history. It lasted fifteen innings and resulted in a 2âÂÂ2 draw, with the game lasting 5 hours and 43 minutes. Only Game 2 of the 2022 Japan Series on October 23, 2022, came close, with the Orix Buffaloes and Tokyo Yakult Swallows playing to a 3âÂÂ3 draw after 12 innings, lasting 5 hours and 3 minutes.
Even though the Central League is historically more victorious, in recent years, the Pacific League has been catching up in titles. Currently, each league has won 38 times. The Pacific League won eight consecutive Japan Series championships from 2013 to 2020, with six by the Fukuoka SoftBank Hawks, and one each by the Hokkaido Nippon-Ham Fighters and Tohoku Rakuten Golden Eagles. The streak was broken in 2021, with the Tokyo Yakult Swallows beating the Orix Buffaloes.
Kazuhisa Inao, as an exception, won the Fighting Spirit Award (in 1956) while playing for the victorious Nishitetsu Lions.
Since 2018, there is a limit of 12 innings in the seven regulation games, with games being called tie games if tied after that time. From 1987 to 2020, the innings limit is abolished starting in extra games (Game 8, et al) if necessary. Since 2021, extra games are played to 12 innings as normal. Starting in the 13th inning of extra games, the World Baseball Softball Confederation two-runner tiebreaker with runners at first and second base, similar to the Japanese High School Baseball Championship (Koshien), will be implemented.

Since 1950, fifteen managers have won the Japan Series multiple times. Osamu Mihara (Whales, Lions), Shigeru Mizuhara (Giants, Flyers), and Tatsuro Hirooka (Swallows, Lions) are the only managers to have multiple teams to wins in the Japan Series. In terms of pennants, eight managers have won a league pennant with multiple teams: Katsuya Nomura, Sadaharu Oh, Shigeru Mizuhara, Osamu Mihara, Tatusro Hirooka, Masataka Nashida, Yukio Nishimoto, and Senichi Hoshino. Nishimoto and Hoshino are the only ones to lead three different teams to the Japan Series.
Two individual awards are given out at the conclusion of the Japan Series: the Most Valuable Player Award, given to the most impactful player on the winning team; and the Fighting Spirit Award, given to the most impactful player on the losing team. As stated above, the FSA was only given to a player on the winning team once; Kazuhisa Inao won it in 1956, despite being on the winning side, the Nishitetsu Lions.
