Definition and Significance of Walk-Off Wins in NPB
A walk-off win occurs when the home team scores the winning run in the bottom of the final inning, ending the game immediately. Since NPB was founded in 1936, countless walk-off moments have thrilled fans. Kazuhiro Kiyohara holds the all-time NPB record with 12 career walk-off home runs, followed by Sadaharu Oh with 10. Including walk-off hits, Katsuya Nomura recorded 29 career walk-off hits. Walk-off victories carry meaning beyond ordinary wins, as the entire stadium erupts in an instant of pure joy. Walk-offs in the Japan Series or Climax Series are etched especially deep in fan memory, representing the pinnacle of baseball drama. MLB's walk-off victories have produced World Series classics. Joe Carter's 1993 walk-off home run remains one of MLB's most famous walk-off moments.

The Legendary Walk-Off - Shigeo Nagashima and the Emperor Game
The most famous walk-off home run in NPB history came on June 25, 1959, during the Tenran Shiai (Emperor Game) at Korakuen Stadium. In the bottom of the ninth inning of a Giants vs. Hanshin Tigers game, Shigeo Nagashima launched a walk-off homer off Minoru Murayama into the left-field stands, giving the Giants a 4-3 victory. Emperor Hirohito and Empress Nagako were watching professional baseball in person for the first time. Murayama later recalled he intended to throw a low-outside pitch. The television rating exceeded an estimated 30 percent in the Kanto region, cementing professional baseball as Japan s national pastime. This single swing became a cultural icon of the Showa era.
Walk-Offs That Decided the Japan Series
Walk-off finishes in the Japan Series carry extraordinary weight. In Game 5 of the 2001 Japan Series, Yakult catcher Atsuya Furuta hit a walk-off home run off Kintetsu pitcher Rick Guttormson to clinch the championship. In 1986, Seibu outfielder Koji Akiyama delivered a walk-off hit against Hiroshima in Game 8 to win the title. In 2014, SoftBank designated hitter Lee Dae-ho hit a walk-off single against Hanshin in Game 5, sealing a 4-1 series victory. More recently, in 2022, Orix slugger Yutaro Sugimoto delivered a walk-off hit in Game 6 to clinch the franchise s first Japan Series title in 26 years. These moments become the defining memories of players careers.

Modern Walk-Offs and Data Analytics
Since the 2010s, walk-off situations have become a subject of data analysis. In the 2023 NPB season, 24 walk-off home runs were recorded, and approximately 120 games ended on walk-off hits overall. From a sabermetric perspective, a batter s WPA (Win Probability Added) in a tied bottom-of-the-ninth at-bat can approach 0.5, making even a walk-off single one of the highest-leverage plays possible. In 2024, DeNA second baseman Shugo Maki hit four walk-off home runs in a single season. The introduction of the tiebreaker rule starting in extra innings from the 10th inning onward in 2018 has also changed walk-off patterns, with sacrifice flies becoming more common as runners start in scoring position.
