The Problem of Lengthening Game Times and NPB's Response
NPB game times have shown a long-term trend of extension. While average game time in the 1970s was approximately 2 hours and 30 minutes, by the 2010s it exceeded 3 hours and 15 minutes. This lengthening has made television broadcast scheduling difficult and has been cited as a contributing factor to younger fans drifting away. NPB has worked on shortening game times since the 2000s. In 2006, a Speed-Up Committee was established, examining measures such as shortening pitchers' intervals between pitches, restricting batters from leaving the batter's box, and reducing between-inning times. However, these efforts remained primarily awareness campaigns and did not lead to mandatory rule changes with penalties. Game time reduction remains an unavoidable challenge for NPB, driven by practical demands of improving fan viewing experience and securing broadcast slots.
MLB's Pitch Clock Introduction and Its Effects
In 2023, MLB officially introduced the pitch clock. The rule requires pitchers to begin their pitching motion within 15 seconds with no runners on base and 20 seconds with runners on. The first-year effects were dramatic. Average game time was reduced by approximately 23 minutes from the previous year's 3 hours 3 minutes to 2 hours 40 minutes, and game tempo clearly improved. Fan satisfaction surveys showed predominantly positive responses, with particularly strong support from younger demographics. However, cases arose where pitchers were called for clock violations and batters were unprepared in time, affecting game flow in some situations. MLB's pitch clock introduction became an important reference case for NPB and served as a catalyst accelerating the discussion of implementation in Japan.
The Introduction Debate in NPB - Arguments For and Against
Following MLB's pitch clock introduction, serious consideration has begun in NPB. Proponents argue that shortening game times is essential for improving fan viewing experience and attracting younger audiences. Games exceeding 3 hours are difficult for after-work fans to watch to completion and burdensome for families with children. Opponents argue that baseball's essence lies in being a sport without time limits. The strategic interplay of timing between pitcher and batter is baseball's greatest appeal, and mechanical time restrictions would diminish that charm. Some also point out that Japanese baseball culture has a tradition of valuing 'ma' (strategic pauses), and the pitch clock is incompatible with this cultural value. NPB's players' union has also shown a cautious stance, expressing the view that a unique system design is needed considering health impacts on players and Japan's climate conditions such as high temperature and humidity in summer.

Multi-faceted Approaches to Game Time Reduction and Outlook
The pitch clock is merely one means of shortening game times, and NPB is exploring multi-faceted approaches. The intentional walk declaration system was introduced in 2018, eliminating the need for four pitches during intentional walks. Replay review time reduction is also being advanced, with time limits for reviews under consideration. Furthermore, reducing between-inning times and limiting warm-up pitches during pitching changes are also on the discussion table. A uniquely NPB initiative drawing attention is the rule change for extra innings. Since 2022, extra innings are limited to 12, effectively setting an upper limit on game time in exchange for increased ties. Whether NPB will introduce a pitch clock going forward will likely be determined after carefully evaluating long-term effects from MLB and compatibility with Japanese baseball culture. NPB needs to find its own solution to the paradoxical challenge of shortening game times while maintaining baseball's appeal.
Physical Impact of Pitch Clocks on Pitchers
The physical impact of pitch clocks on pitchers is a significant concern that cannot be overlooked. Shortening the interval between pitches may deprive pitchers of heart rate recovery time and routine preparation, potentially accelerating fatigue accumulation. In MLB, trends in pitcher injury list placements following the 2023 pitch clock introduction have drawn close attention. Relief pitchers face particular pressure, as their between-inning preparation time is already limited while pitch intervals are further constrained, creating a dual time squeeze. However, some pitchers view the change positively, noting that pitching at a faster tempo creates rhythm and reduces physical tension. If NPB considers adoption, the focal point will be reconciling the rule with the traditional Japanese pitching culture of deliberate pauses between pitches. Whether performing breathing adjustments and mental concentration routines under time pressure affects performance requires careful study.
Impact on Fan Experience and Broadcasting Business
Pitch clocks have the potential to transform fan experience through shorter game times. In MLB, average game duration decreased by approximately 30 minutes following the 2023 pitch clock introduction, and attendance showed an upward trend. Games exceeding three hours pose a particular burden for families with children and weekday attendees, and increased predictability of game length reportedly enhances willingness to attend. However, the broadcasting business presents a more complex picture. Japanese professional baseball broadcasts have been retreating from terrestrial television, with streaming services becoming the primary viewing platform. On streaming platforms, longer game times are not necessarily a disadvantage, as viewing duration correlates with advertising revenue. Unlike terrestrial broadcasts, there is no broadcast window overrun problem. The benefit of shorter games is most significant for stadium attendees, while the impact on streaming viewers remains limited, creating a dual-faceted situation.
Impact of Pitch Clocks from the Batter's Perspective
Pitch clock discussions tend to focus on pitchers, but the impact on batters cannot be ignored. When the interval between pitches shortens, the time batters have to read the next pitch type, confirm their batting stance, and perform mental resets is compressed. MLB data from 2023 showed no major fluctuation in batting average or home run totals in the first year, though a slight upward trend in strikeout rate was observed. If batters are disadvantaged, the value of so-called fouling-off tactics may decline. The strategy of extending at-bats by fouling off pitches to increase the pitcher's pitch count becomes harder to sustain when combined with accelerated tempo, as batter concentration becomes more difficult to maintain. In NPB, a batting culture that values fighting off pitches with two strikes is deeply rooted. Practical challenges of fitting batter routines such as adjusting batting gloves and taking practice swings within time limits have also become subjects of discussion.
