The 2023 was the championship series of Nippon Professional Baseball's (NPB) season. The 74th edition of the Japan Series, it was a best-of-seven playoff between the winners of the Central League (CL) and Pacific League's (PL) postseason tournament, the Climax Series. The Hanshin Tigers and Orix Buffaloes each won their respective CL and PL titles in the regular season, which advanced both teams directly to the final stages of the Climax Series; each then earned Japan Series berths by winning their respective CL and PL Climax Series.

The Tigers and the Buffaloes both play in Japan's Kansai region, which made it only the second time that two Kansai-based teams played each other in the Japan Series, the other being in 1964. Because of the teams' close proximity, the series was dubbed "The Great Kansai Derby" and the "Namba Line Series" by Japanese media. While Orix won the previous year's championship, the last title for the Tigers came 38 years prior in 1985, then the second-longest active championship drought in NPB. Starting on October 28, 2023, and ending on November 5, 2023, Hanshin won the series in seven games, thus ending their championship drought and the Curse of the Colonel, a superstition that was believed by some to be responsible for the team's struggles. Koji Chikamoto was named the series' Most Valuable Player and Kotaro Kurebayashi won the Fighting Spirit Award as Orix's best player in the series.

Background

The Hanshin Tigers won their eleventh-straight game on September 14, capping off their longest win streak of the season. The win also clinched the team their first Central League (CL) pennant since 2005 and their sixth overall. Hanshin finished the previous season in third place with a losing record. Manager Akihiro Yano stepped down at the end of the year and Akinobu Okada, a Tigers player during the team's only championship in 1985, was brought back a second time to again manage the team. After back-to-back seven- and nine-game win streaks from May 11 to 30, the Tigers maintained first place for the remainder of the season. In July, Shintaro Yokota, a former Tigers player that was forced to retire in 2019 because of brain cancer, died. Yokota was a former teammate of several current players, including Suguru Iwazaki, who carried his uniform on the field and held it during the pennant celebration. League winners for the first time since 2005, the Tigers advanced directly to the CL Climax Series' final stage where they played the Hiroshima Toyo Carp. With the help of the one-win advantage the winners of the pennant receive, Hanshin swept the Carp in three games to advance to the Japan Series for the first time since 2014.

Six days after the Tigers clinched their title, the Orix Buffaloes secured their third-straight and 15th overall Pacific League (PL) pennant. Despite slugging outfielder Masataka Yoshida leaving the team in the offseason to play in Major League Baseball (MLB), Orix was still able to lead in the standings throughout the majority of the season and clinched the title relatively early compared to the previous two seasons. It was the Buffaloes third three-peat in its history, its first since 1975–1978 when they won four straight as the Braves. It was the first three consecutive Pacific League championships since the Seibu Lions won five straight between 1990 and 1994. Orix advanced directly to the PL Climax Series' final stage where they played the Chiba Lotte Marines for the right to move on to the Japan Series. The Buffaloes defeated the Marines four games to one, including their one-win advantage. It was their third straight Japan Series appearance.

Series notes

The Hanshin Tigers' and the Orix Buffaloes' home stadiums are Koshien Stadium and Kyocera Dome, respectively. The stadiums' respective cities, Nishinomiya and Osaka, both fall within Japan's Kansai region and are just over twenty minutes apart via train. Because of the close proximity, the series was dubbed "The Great Kansai Derby" and the "Namba Line Series" for the train line that helps connect the two stadiums, the Namba Line. This Japan Series was only the second time that two Kansai-based teams have played each other, the other being the 1964 Japan Series when the Nankai Hawks defeated the Tigers . Despite Orix's recent success, Hanshin has a much larger cultural presence. Founded in 1935, the Tigers were formed during the earliest days of professional baseball in Japan. Additionally, the team plays in historic Koshien Stadium, the oldest stadium in Nippon Professional Baseball (NPB). The team's championship struggles also add to its storied history. Conversely, the Buffaloes were formed from a merger between the Orix BlueWave and the Kintetsu Buffaloes during the contentious 2004 Nippon Professional Baseball realignment. Prior to that the team played in Nishinomiya and Kobe before calling Osaka home after the merger. Economists predicted that the series' economic impact in Japan could surpass the benefits of the Japan national baseball team winning the 2023 World Baseball Classic earlier in the year.

The series was the third straight Japan Series appearance for Orix, losing in 2021 but winning in 2022, their fifth championship. Hanshin, however, entered the series with much less recent Japan Series experience. The team last appeared in a Japan Series in 2014, a series they lost. The last and only time the Tigers won a championship was in 1985. The 38-year-long championship drought was the second longest active drought in NPB, only one year shorter than the Carp's. The series garnered worldwide attention for the Tigers because it could allow them to break the so-called "Curse of the Colonel", a superstition that started in 1985 that was believed by some to be responsible for Hanshin's struggles to win another Japan Series. Tigers manager Okada was a Tigers player during their last title in 1985 and also led the team to a Japan Series berth in 2005 during his first managerial stint with Hanshin, only to be swept by the Marines.

Both teams had similar statistics during the regular season. The Buffaloes and Tigers had the best and second-best records in NPB, respectively, with and . Similarly, the Hanshin pitching staff's 2.66 team earned run average (ERA) was the NPB best, with the Buffaloes a close second with a 2.73 team ERA. In their only regular season meeting during interleague play in June, Orix won the series . Home field advantage for the Japan Series alternates between the Pacific and Central leagues every year. For this series, it was the PL's turn to hold the advantage, so home field was awarded to the Buffaloes. The designated hitters were not used in games three, four, and five, played at the Tigers' Koshien Stadium, as the rule has never been adopted in the Central League.

Sponsor Sumitomo Mitsui Banking Corporation (SMBC) sponsored the event for the tenth consecutive year and held the naming rights for the series, with its full title being "2023 SMBC Japan Series".
