The Complete Picture of NPB Perfect Games
A perfect game occurs when a starting pitcher completes at least nine innings without allowing a single baserunner, representing the ultimate pitching achievement. In NPB, 16 pitchers have accomplished this feat, beginning with Hideo Fujimoto of the Yomiuri Giants in 1950 through to Roki Sasaki of the Chiba Lotte Marines in 2022. Compared to MLB's 24 perfect games, the per-game achievement rate is roughly equivalent, illustrating just how rare the feat is. A perfect game requires not only elite pitching but also flawless defense, favorable umpiring, and even cooperative weather conditions. Retiring 27 consecutive batters means allowing zero hits, walks, hit batters, and errors - demanding perfect coordination between pitcher and fielders.
Early Era Achievers Through the Golden Age
NPB's first perfect game came on June 28, 1950, when Hideo Fujimoto shut out the Nishi-Nippon Pirates at Aomori Municipal Stadium on just 94 pitches with 7 strikeouts. The 1950s and 1960s saw a relative cluster of perfect games, with Fumio Takechi (Kintetsu, 1955), Koretomo Miyaji (Kokutetsu, 1956), and Masaichi Kaneda (Kokutetsu, 1957) among the achievers. Kaneda, who would amass a career 400 wins, was just 23 years old at the time. The 1960s added Gentaro Shimada (Taiyo, 1960) and Yoshimi Moritaki (Kokutetsu, 1961), reflecting the pitcher-dominant era following the two-league split. In 1970, Yoshiro Sotokoba of the Hiroshima Carp achieved the feat, foreshadowing the team's golden dynasty.
The 28-Year Drought and Sasaki's Breakthrough
After Hiromi Makihara of the Yomiuri threw a perfect game against Hiroshima at Fukuoka Dome on May 18, 1994, NPB endured a 28-year drought. During this gap, elite pitchers like Daisuke Matsuzaka, Yu Darvish, and Masahiro Tanaka starred but none achieved perfection. Improved hitting, pitch-count awareness, and the bullpen specialization era all contributed. Roki Sasaki shattered the drought on April 10, 2022, at ZOZO Marine Stadium against the Orix Buffaloes. The 20-year-old needed just 105 pitches, striking out a record 19 batters including 13 consecutive strikeouts. Armed with a fastball reaching 164 km/h and a devastating forkball, Sasaki delivered one of the most dominant performances in baseball history.

The Significance of Perfect Games in Baseball History
A perfect game is both an individual record and a team achievement. In Sasaki's perfect game, catcher Tora Matsukawa's expert pitch-calling maximized Sasaki's stuff, while shortstop Yudai Fujioka handled difficult grounders flawlessly. The strict pitch-count management of the 2020s makes it increasingly rare for starters to exceed 100 pitches - NPB starters averaged about 92 pitches per game in 2023. Given that a perfect game requires facing at least 27 batters, reconciling pitch limits with perfection will only grow harder. Meanwhile, Statcast-style tracking data now enables far more granular analysis of perfect-game performances. When and by whom the next perfect game will occur remains unpredictable, but that very rarity is what continues to captivate baseball fans worldwide.
The Catchers and Defenders Behind Perfect Games
A perfect game is recorded as a pitcher's feat, yet the contributions of the catcher and defensive teammates cannot be overlooked. In Hideo Fujimoto's 1950 perfect game, catcher Shigeru Fujio provided steady guidance behind the plate. When Hiromi Makihara achieved perfection in 1994, Shinichi Murata's masterful pitch sequencing shut down the Hiroshima lineup. For Roki Sasaki's 19-strikeout perfect game in 2022, 18-year-old rookie catcher Tora Matsukawa expertly alternated between inside fastballs and forkballs, showing composure far beyond his limited experience. On defense, shortstop Yudai Fujioka's sure-handed play was complemented by center fielder Takashi Ogino's diving catch of a sharp liner in the fifth inning. While strikeouts constitute a large portion of the 27 outs, converting batted balls into outs with unwavering concentration is the true foundation of any perfect game.
Near Misses - The Greatest Almost-Perfect Games
NPB history is rich with pitching performances that came agonizingly close to perfection. On August 27, 2006, Masa Yamamoto of the Chunichi Dragons carried a perfect game against the Yokohama BayStars into the eighth inning with two outs before surrendering a hit to the 26th batter. Given that Yamamoto was 41 years old at the time, the attempt bordered on the miraculous. On September 14, 2019, Kodai Senga of the SoftBank Hawks held the Chiba Lotte Marines hitless and walkless through eight innings and two outs before the bid ended. In 2012, Toshiya Sugiuchi of the Yomiuri Giants threw a no-hitter against the Nippon-Ham Fighters but issued a walk that prevented perfection. These near misses illuminate the vast history of failure behind the 16 recorded perfect games, underscoring how extraordinarily difficult it is to retire 27 consecutive batters.
How Pitch-Count Limits Have Structurally Changed Perfect Games
The growing emphasis on protecting pitchers' arms has structurally altered the conditions for achieving a perfect game. Since the 2010s, NPB clubs have increasingly set starting pitcher limits around 100 pitches, and in the 2023 season starters averaged about 92 pitches per outing. Completing a perfect game requires facing at least 27 batters, and high-strikeout pitchers accumulate counts faster. Roki Sasaki's 2022 perfect game was remarkably efficient at 105 pitches for 19 strikeouts, yet had his manager called for a reliever once the count exceeded 110, the historic achievement would have evaporated. In the 1960s, complete games were routine and the pitch-count barrier did not exist. In an era of strict bullpen specialization, the manager's willingness to let a starter continue has become a critical factor in whether perfection can be achieved.
