The Hirokazu Ibata era for Samurai Japan is over. Following Japan’s disappointing 8-5 loss in the quarterfinals of the 2026 World Baseball Classic, the 50-year-old manager announced his resignation from the position.
“Results are everything,” he said.
It’s common practice for a Japanese manager to step down after the WBC, as the tournament naturally marks the conclusion of their tenure. Win or lose, this WBC was likely the end of the Ibata-era Japan. Still, the manner in which they lost presents a narrative that Ibata is taking responsibility and resigned as a result of Japan crashing out of the tournament in its worst-ever finish.
Before the Classic
Ibata was hired in October 2023, replacing Hideki Kuriyama, who led Japan to triumph at the 2023 WBC and immediately retired.
Before taking the helm, the former Chunichi Dragons and Yomiuri Giants standout infielder had managed Japan at the Under-15 and Under-12 youth levels and also spent brief stints coaching with Yomiuri and the senior national team. Beyond that, he remained active in the baseball world by sharing his opinions through television programs and his popular YouTube channel, IbaTV.
He went on to manage Samurai Japan in three major tournaments — the 2023 Asia Professional Baseball Championship, the 2024 Premier12, and the 2026 World Baseball Classic — as well as smaller exhibition series, including matchups against the All-Europe All-Stars in March 2024 and Team Korea in November 2025.
Japan entered all three tournaments as the defending champion, but Ibata only managed to defend the APBC title, and even that required extra innings in the final.
Japan’s stunning 4-0 loss to Chinese Taipei in the 2024 Premier12 snapped its 27-game winning streak in major international tournaments dating back to 2019 and ended its unbeaten run in the competition. But doubts about Ibata had been building well before the final.
Some of the circumstances were beyond his control, as key players like Kazuma Okamoto, Chusei Mannami, and Hiromi Itoh were initially called up before withdrawing from the team due to injuries. Even so, Ibata was unable to assemble Japan’s strongest possible roster.
Instead of a star-studded squad more in line with the 2019 Premier12 championship team, the roster felt closer to an NPB “C team.” Moreover, he drew criticism for several questionable lineup choices throughout the tournament, such as batting star slugger Shugo Maki sixth and starting Keita Sano over Kotaro Kiyomiya. Some fans even wondered whether the program still cared as much about the Premier12 as Chinese Taipei simply seemed hungrier to win.
In hindsight, some of Ibata’s decisions can be understood in the context of building up for the WBC. He wanted Maki to grow comfortable hitting lower in the order, which turned out to be his spot at the WBC. He also entrusted players like Shota Morishita and Kaito Kozono with important roles, believing they would become important pieces of the eventual WBC roster.
It should also be acknowledged that he used the Premier12 to acclimate pitchers like Koki Kitayama and Chihiro Sumida to different roles, while also helping fully unlock Shoma Fujihira — developments that all carried over to Japan’s WBC staff. Still, a silver medal at the Premier12 was only really acceptable if Japan followed it up with another strong showing at the WBC.
The World Baseball Classic
A major component of a national team manager’s job is recruiting talent, and in that respect, Ibata was more successful than some of his predecessors. Unlike Koji Yamamoto in 2013 and Hiroki Kokubo in 2017 — both of whom failed to secure commitment from Japan’s top Major League talent — Ibata got most of the biggest stars to buy in, just like Kuriyama.
The position-player group was essentially a dream team, featuring Shohei Ohtani, Seiya Suzuki, Masataka Yoshida, Munetaka Murakami, and Kazuma Okamoto. Of course, he was unable to bring in pitchers like Roki Sasaki, Shota Imanaga, Kodai Senga, or Tatsuya Imai, but those absences were not his fault, as each had specific reasons for not participating.
Still, Ibata made several controversial decisions leading into the tournament, from selecting Sosuke Genda and Kaito Kozono as his shortstop duo to deploying Seiya Suzuki out of position in center field and relying on Tomoyuki Sugano as a pillar of the rotation.
Having NPB stars like Teruaki Sato and Shota Morishita begin the tournament on the bench also drew criticism from fans, though to his credit, he eventually showed the boldness to start Sato over a struggling Kensuke Kondoh in the quarterfinal.
Japan ultimately went undefeated in Pool C in Tokyo and flew to Miami needing three more wins to claim a fourth WBC title, but their run ended at the first knockout hurdle with a quarterfinal loss.
There is no shame in losing to Venezuela, a team that was at least as talented as Japan on paper, but Ibata’s team had looked vulnerable even before that defeat.
They lost two exhibition games before the tournament, fell behind against both Korea and Australia in pool play, and remained scoreless against Czechia until breaking through in the eighth inning. Aside from a 13-0 mercy-rule victory over a Chinese Taipei team that did not even use its best pitchers, none of Japan’s performances felt particularly convincing.
What Went Wrong?
Before placing all the blame on management, Japan must acknowledge that Venezuela was simply the better team. They had more firepower, came up with the bigger hits, and executed in the crucial moments where Japan could not.
That said, the loss put a spotlight on Ibata’s shortcomings in high-pressure game management and roster construction.
In the Premier12 final, he stuck with a laboring Shosei Togo for over 80 pitches before Chieh-Hsien Chen broke the game open with a three-run home run. Japan never recovered and lost 4-0. Japan had grown accustomed to escaping tight games against inferior opposition, but when it mattered most, his decisions did not pay off.
Up 5-2 in the top of the fifth against Venezuela, Ibata tried unconventional bullpen moves to close out the game, turning to top starters Chihiro Sumida and Hiromi Itoh in short relief.
Sumida allowed a two-run homer to Maikel Garcia in the fifth to cut the lead to one, and Itoh surrendered a go-ahead three-run shot to Wilyer Abreu in the sixth that proved insurmountable.
Bringing in Sumida, who was dominant against Australia, over a shaky veteran like Yusei Kikuchi was certainly justifiable, but even so, more conventional relief options were available. Moreover, Itoh had been in poor form throughout the tournament, with his fastball velocity down several ticks from his regular season averages, putting the reigning Sawamura Award winner at a disadvantage.
Using Atsuki Taneichi, Japan’s most effective arm all tournament, in the seventh and eighth innings made sense, but by then, the game was already lost.
Shoma Fujihira and Yuki Matsumoto, meanwhile, combined to throw just 1 ⅔ innings over the entire tournament, while Koki Kitayama also has prior experience in high-leverage relief. Those three were more natural options for the fifth and sixth.
More broadly speaking, Ibata’s pitching staff construction was unorthodox from the outset, with 11 traditional starting pitchers and only three true relievers.
Part of that was out of his control, as Daichi Ishii, Kaima Taira, and Yuki Matsui withdrew due to injuries. However, other available high-octane weapons like Shunpeita Yamashita, Shinya Matsuyama, and Kazuki Sugiyama were left off the roster entirely.
Ibata’s Legacy
Ibata will not be remembered as a great skipper by many fans after overseeing Japan’s Premier12 collapse and worst-ever WBC finish, though he could return as an NPB manager in the future.
His strategy often felt disjointed, leaning on stereotypical Japanese small ball with bunts and late-game aggression on the bases, while also deviating from convention by forcing defensive liabilities like Yoshida and Suzuki into the outfield to prioritize getting MLB bats into the lineup.
But he does deserve credit for the things he got right.
He was respected within the clubhouse and generally brought a positive energy to the field. As Jim Allen has noted, good managers protect their players, and when asked whether Shugo Maki’s base-running blunder with the bases loaded against Australia hurt Japan’s confidence, Ibata took responsibility, saying, “It was my mistake for not asking more quickly for a video review.”
He was also willing to think outside the box. In 2024, he called up three college prospects — Rui Muneyama, Yuto Nakamura, and Yumeto Kanemaru — to the senior national team for an exhibition series against Team Europe. Nakamura and Kanemaru contributed to a combined perfect game for Japan, and just two years later, the latter earned a spot on the WBC roster, with that early experience paying dividends.
The Next Chapter
With Ibata stepping down, Samurai Japan will now begin its search for a new manager, with a successor likely to be announced this fall ahead of an international cycle that includes the 2027 Premier12, the 2028 Los Angeles Olympics, and the 2030 World Baseball Classic.
Several high-profile candidates have already emerged, headlined by some of the most decorated and respected figures in Japanese baseball.
Kimiyasu Kudo boasts the strongest résumé, with 11 Japan Series titles as a player and five as a manager, though his time away from the game since 2021 raises questions.
Satoshi Nakajima, who led the Orix Buffaloes to three straight Japan Series appearances from 2021 to 2023, is viewed as a relatively modern and progressive manager, while World Series winner Tadahito Iguchi brings strong international credibility.
Hideki Kuriyama, who led Japan to the 2023 championship and was recently inducted into the Japanese Baseball Hall of Fame, represents a sentimental option should he come out of retirement.
Atsuya Furuta offers a compelling blend of traditional instincts and analytical thinking, though his role in the 2004 players’ union strike may complicate his standing within the NPB establishment.
Legends of the sport like Hideki Matsui and Ichiro Suzuki also loom as statement hires, though both lack managerial experience and are not especially qualified for the job.
Other names, including Yoshinobu Takahashi, Masato Yoshii, Koji Akiyama, and Tatsunori Hara, round out a wide-ranging and intriguing field as Samurai Japan looks toward its next era in an ever-evolving baseball landscape.
