The Shock of Delayed Opening and Empty Stadiums
NPB's 2020 season, originally scheduled to begin on March 20, was delayed approximately three months due to the COVID-19 pandemic, finally opening on June 19 with no spectators. It was the first time in history that the start of professional baseball, which had continued uninterrupted even during postwar turmoil, was delayed so significantly. The regular season was shortened from the usual 143 games to 120, and interleague play and the All-Star Game were cancelled. Spectator admission was gradually permitted from July 10, initially capped at 5,000 per game. With Tokyo Dome's capacity of approximately 46,000, the sight of barely 10% occupancy was unprecedented, and the novel experience of clearly hearing players' shouts and bat cracks through TV broadcasts became a talking point. Total annual attendance across all 12 teams was approximately 8.5 million, a historic 68% decline from the roughly 26.53 million recorded in 2019.
Infection Control and Game Operations Reform
In May 2020, NPB established the NPB COVID-19 Infection Prevention Guidelines, mandating uniform infection control measures across all 12 teams. Players and staff were required to submit temperature checks and health condition sheets before games, and mask-wearing in the dugout became standard. Traditional customs such as high-fives and team huddles were prohibited, with fist bumps becoming the new norm after scoring. A special regulation was also established to cancel a team's next two games if a player tested positive during a game. In the 2020 season alone, 14 games were cancelled or postponed due to infection-related issues, and teams including SoftBank Hawks and Hanshin Tigers temporarily suspended team activities. Facility modifications including stadium disinfection, expanded bullpen spacing, and distributed locker room usage reportedly cost an estimated 3 billion yen or more across all 12 teams combined.
Digital Viewing and New Fan Experiences
The constraints of spectatorless and limited-capacity games ironically accelerated the development of digital viewing culture. Subscriptions to DAZN and team-operated streaming services increased by over 40% year-on-year in 2020, and Pacific League TV's paid membership reached an all-time high that year. SoftBank introduced a Remote Cheering System at PayPay Dome, playing fan cheers sent via smartphones through stadium speakers. Rakuten developed a Virtual High-Five feature at Rakuten Mobile Park Miyagi, synchronizing footage of players waving at cameras with fans' screens. Teams also strengthened two-way communication with players through social media, with the Yomiuri Giants' YouTube subscriber count roughly tripling during 2020. Many of these digital initiatives have continued beyond the pandemic, and a hybrid viewing style combining stadium attendance with online experiences is becoming NPB's new standard.

Post-COVID NPB and Lasting Lessons
With COVID-19 reclassified as a Category 5 infectious disease in May 2023, NPB attendance entered a full recovery trajectory. Total attendance for the 2023 season reached approximately 24.72 million, recovering to about 93% of the pre-pandemic 2019 figure. The tailwind from Japan's WBC championship victory also helped, and Central League stadiums in the Kansai region were packed daily, boosted by the Hanshin Tigers' first league title in 18 years. Meanwhile, some measures introduced during the pandemic have become permanent changes. Electronic ticket adoption rose from approximately 25% in 2019 to about 70% in 2023, and cashless payment implementation within stadiums accelerated. Player health management awareness improved dramatically, with a culture of not pushing through even minor ailments taking root. While the pandemic dealt severe economic damage to NPB, it simultaneously brought three structural changes: accelerated digitalization, diversified fan experiences, and heightened health management awareness. This experience serves as a valuable lesson strengthening the baseball world's resilience against future crises.
Player conditioning and performance effects
The roughly three-month delay to opening day forced players to reset their conditioning from spring camp and re-train independently. Pitchers were particularly affected: the 12-team average ERA in 2020 worsened by approximately 0.2 points compared to the previous year. Irregular relief-pitcher usage intervals and the difficulty of maintaining game-level sharpness were cited as contributing factors. Hitters suffered from a lack of data on opposing pitchers due to cancelled exhibition games, and several teams saw lower batting averages early in the season. Conversely, the shortened 120-game schedule reduced late-season fatigue accumulation, and the number of players sidelined with injuries actually trended downward.
Financial impact on team management
Empty stadiums and attendance caps shook the revenue foundations of NPB clubs. Team income derives from tickets, merchandise, food and beverage sales, and sponsorships, yet gate revenue in 2020 fell by an estimated 70 percent or more compared to the prior year. Clubs that owned their home stadiums bore especially heavy fixed maintenance costs. Total player salaries dipped only slightly during the 2020 offseason, but indirect effects such as staff bonus cuts and hiring freezes emerged across organizations. Peripheral bodies also suffered: the Shikoku Island League Plus reduced its 2020 schedule by roughly 40 percent. From professional to amateur levels, Japanese baseball as a whole faced an unprecedented financial ordeal.
Ripple effects on international events and player development
The pandemic's effects reached beyond NPB to international competition and player development. The 2020 Tokyo Olympics were postponed by one year, forcing the national team's roster planning back to square one. Overseas winter leagues in Asia and Hawaii were cancelled, depriving developing players of valuable game experience. In high-school baseball, both the 2020 Spring Invitational and Summer Championship at Koshien were cancelled, an irreplaceable loss for third-year students. A substitute exhibition event was held at Koshien but carried no official tournament status. Scouts who relied on Koshien performance struggled with the lack of footage, and the 2020 draft saw a higher-than-usual proportion of picks from corporate and university teams.
