The manager who beat Team USA is now taking a serious look at Korean baseball. Hideki Kuriyama, the architect of Japan’s unforgettable 2023 World Baseball Classic championship run, traveled to Seoul and walked into KBO headquarters — sitting down with the league’s commissioner, and separately with Korea’s national team leadership, to talk about what it takes to make Korean baseball more competitive on the world stage.
The Visit
On August 20, Hideki Kuriyama — now the Chief Baseball Officer of the Nippon-Ham Fighters in Japan’s Nippon Professional Baseball (NPB) league — arrived at KBO headquarters in Dogok-dong, Gangnam-gu, Seoul. He wasn’t traveling alone. Alongside him were officials from the Fighters organization and marketing representatives from PLM, or Pacific League Marketing, the joint marketing company formed by Japan’s six Pacific League clubs. Together, the delegation met with KBO Commissioner Heo Koo-yeon for a direct, high-level conversation between two of Asia’s most important baseball organizations.
The topics on the table were substantive rather than ceremonial. According to reporting from South Korean outlets, the discussion centered on player development strategies aimed at strengthening international competitiveness, along with a candid exchange about how the sport is changing under new systems — most notably the Automatic Ball-Strike system, better known as ABS, or what American fans would likely call the “robot umpire” system for calling balls and strikes.
Kuriyama didn’t stop at the commissioner’s office. In a separate meeting the same day, he sat down with Ryu Ji-hyun, manager of Korea’s national baseball team, and Jo Kye-hyun, chairman of the KBO’s Strengthening Committee. That conversation focused specifically on how to boost the competitiveness of Team Korea on the international stage — a topic Kuriyama, of all people, is uniquely positioned to speak to.
Who Is Hideki Kuriyama?
For readers outside Japan and Korea who may not immediately recognize the name, Hideki Kuriyama is one of the most respected figures in Japanese baseball. He managed Japan’s national team, known as Samurai Japan, from 2022 through 2023, a stretch that culminated in the single most-watched moment in recent international baseball history: Japan’s championship run at the 2023 World Baseball Classic. Before that, he built his managerial reputation over more than a decade running the Nippon-Ham Fighters in NPB, developing a track record as one of the sport’s more thoughtful, development-minded leaders in Japan. Today, he holds the title of Chief Baseball Officer for the Fighters, a front-office role that puts him at the center of the organization’s baseball operations, player development philosophy, and now, apparently, international outreach.
That last part is what makes his trip to KBO headquarters newsworthy well beyond Korea’s borders. Kuriyama isn’t just a former national team manager making a courtesy call — he’s a current, sitting baseball executive from a rival league, walking into a competitor’s headquarters to talk shop about player development and rule changes. That’s a meaningfully different kind of visit than a retired legend dropping by for a photo opportunity.
Remembering the 2023 WBC Final
It’s difficult to overstate how vividly American baseball fans remember the game Kuriyama’s team won. The 2023 World Baseball Classic final between Japan and the United States delivered one of the most iconic finishes in the tournament’s history: with Japan clinging to the lead in the ninth inning, manager Kuriyama turned to his ace, Shohei Ohtani, to close it out. Ohtani — at the time already a two-way superstar for the Los Angeles Angels — took the mound to face Mike Trout, his Angels teammate and one of the most feared hitters of his generation, representing Team USA at the plate. The at-bat ended with Ohtani striking out Trout for the final out of the tournament, sealing Japan’s championship in a moment that instantly became one of the sport’s most replayed clips.
That final out wasn’t just a great piece of theater — it was the culmination of a full tournament run under Kuriyama’s leadership, one that saw Japan beat a stacked United States roster to claim the title. For any American baseball fan who tuned into that final, Kuriyama’s name is inseparable from that moment. He’s the manager who out-thought and out-executed Team USA on the biggest international stage the sport has, with the two biggest names in the sport, Ohtani and Trout, squaring off for the final pitch.
What Was Discussed in Seoul
Based on Korean media coverage of the visit, the substance of the meetings broke down into two connected conversations. The first, with KBO Commissioner Heo Koo-yeon, covered player development strategies for strengthening international competitiveness — essentially, how Korean baseball can produce players and teams capable of competing at the highest international level, the kind of level Kuriyama’s Japan squad operated at during that 2023 WBC run. Alongside that, the two sides discussed how the sport itself is evolving through new systems, with the Automatic Ball-Strike system singled out as a specific point of shared interest.
The second conversation, held separately, brought Kuriyama together with Korea’s national team manager Ryu Ji-hyun and KBO Strengthening Committee chairman Jo Kye-hyun. This meeting zeroed in more narrowly on the Korean national team specifically — how to make Team Korea stronger and more competitive against the rest of the world, a subject where Kuriyama’s own experience managing Samurai Japan through a championship run gives his perspective real weight.
What wasn’t part of the public reporting is any specific agreement, formal partnership, or concrete commitment coming out of these meetings. Both conversations appear to have been exactly what they were described as: an exchange of views between baseball people who take the international game seriously, rather than the announcement of a new joint program or formal deal. That distinction matters for accurately understanding the story — this was a substantive dialogue, not a signed partnership.
Why Japan-Korea Baseball Cooperation Matters
To an American audience, the idea of a Japanese baseball executive touring a Korean league headquarters might not immediately register as significant. But within the context of Asian baseball, Japan’s NPB and Korea’s KBO are the two most established, most competitive professional leagues on the continent, and they’ve spent decades in a complicated mix of rivalry and cooperation. Both countries send teams to international competitions like the WBC and the Asian Games, both have produced major stars who’ve gone on to MLB success, and both leagues watch each other’s structural decisions closely — coaching philosophy, player development pipelines, and rule innovations included.
A visit like this one is a signal that the two sides see value in talking directly rather than only competing indirectly. Kuriyama isn’t simply an ex-national-team manager reminiscing about a title run; he’s an active NPB front-office figure whose current job involves shaping how the Fighters organization develops talent and engages with the broader baseball business, including through PLM, the Pacific League’s shared marketing arm. Having that kind of executive, along with PLM’s marketing representatives, sit down with the KBO commissioner suggests interest that extends beyond a single friendly conversation — even without any confirmed details about what, if anything, comes next.
For American fans following the globalization of baseball more broadly — a trend accelerated by stars like Ohtani, Kim Ha-seong, and a growing pipeline of Asian talent making an impact in MLB — this kind of cross-league dialogue between Japan and Korea is part of the underlying infrastructure that makes international baseball better. Stronger, more competitive leagues in both countries mean stronger national teams, which means more compelling tournaments like the WBC, and ultimately more talented players entering the global pipeline that eventually reaches MLB rosters.
The ABS System Both Leagues Are Watching
One of the specific topics raised during the KBO meeting deserves its own explanation for American readers: the Automatic Ball-Strike system, commonly abbreviated as ABS. This is the technology-driven system, sometimes nicknamed the “robot umpire,” that uses tracking technology to call balls and strikes automatically rather than leaving every pitch to a human home plate umpire’s judgment. The KBO has been at the forefront of testing and implementing ABS in a real professional league environment, making it a genuine case study for other leagues worldwide — including NPB and, eventually, MLB — that are weighing whether and how to adopt similar technology.
That’s precisely why a conversation about ABS between a KBO commissioner and a visiting NPB executive is worth paying attention to. Korea’s league has functioned as something of a live laboratory for automated strike-zone technology, and how that experiment is playing out — for player adjustment, for game pace, for umpiring consistency — is exactly the kind of practical information a rival league’s front office would want direct insight into before making its own decisions. It’s a reminder that even as leagues compete for talent and attention, they still have strong incentives to learn from each other’s structural experiments.

Frequently Asked Questions
What is the Automatic Ball-Strike System?
The Automatic Ball-Strike system, or ABS, is a technology-based system that automatically determines whether a pitch is a ball or a strike, removing that specific judgment call from the home plate umpire. It’s often referred to informally as the “robot umpire” system. The KBO has been a notable early adopter of ABS in real professional games, which has made Korea’s league a closely watched reference point for other baseball organizations — including NPB in Japan and MLB in the United States — as they evaluate whether and how to bring similar automated technology into their own games.
Did Kuriyama and the KBO announce any formal partnership?
Based on available reporting, no formal partnership or specific agreement was announced. The visit was described as a meeting and an exchange of views — covering player development strategy and the ABS system with Commissioner Heo Koo-yeon, and national team competitiveness with Korea’s national team manager and KBO’s Strengthening Committee chairman. No details of a signed deal, joint program, or concrete commitments have been reported.
What is PLM, and why were its representatives part of the delegation?
PLM stands for Pacific League Marketing, a joint company formed by the six clubs that make up NPB’s Pacific League, including the Nippon-Ham Fighters. It functions as a shared marketing and business arm for those six teams. Its representatives joining the trip to KBO headquarters alongside Kuriyama and Fighters officials suggests the visit carried a business and marketing dimension in addition to the baseball operations conversation about player development and league rules.
Why is Hideki Kuriyama such a recognizable name to American baseball fans?
Kuriyama managed Japan’s national team, Samurai Japan, to the championship at the 2023 World Baseball Classic — a tournament where Japan defeated Team USA in the final. That final is best remembered in the United States for its last pitch: Shohei Ohtani, already a household name in MLB, struck out his own Angels teammate Mike Trout to secure the win for Japan. That single moment made Kuriyama, as the manager who called the shots throughout that championship run, instantly recognizable to American fans who watched the tournament.
Looking Ahead
There’s no confirmed roadmap yet for what follows this visit, and it would be premature to read a single day of meetings as the start of a formal Japan-Korea baseball alliance. But the shape of the day itself — a sitting NPB front-office executive with a championship pedigree, accompanied by his club’s officials and a league-wide marketing arm, sitting down first with the KBO’s top official and then separately with Korea’s national team leadership — is not the kind of itinerary that happens by accident. It reflects a level of mutual interest between two of Asia’s premier baseball organizations that goes beyond a courtesy visit.
For KBO, having a figure like Kuriyama take player development and international competitiveness seriously enough to travel to Seoul and discuss it directly is itself a form of validation — a signal that Korean baseball’s ongoing evolution, ABS included, is being watched closely by people who’ve actually won at the highest level of international competition. For NPB and the Fighters, the visit offers a direct line into how a rival league is experimenting with the kind of rule changes NPB itself may eventually have to consider, along with a firsthand look at how Korea is trying to build a more competitive national team program.
And for American fans who remember exactly where they were when Ohtani struck out Trout to finish off that 2023 WBC final, there’s a simple thread worth following here: the manager behind that unforgettable finish is still very much shaping the direction of baseball in Asia, well beyond his time on the Samurai Japan bench. Whether this particular trip to Seoul turns into something more formal down the line, or simply remains a valuable one-day exchange of ideas between two leagues that respect each other, it’s a reminder that the sport’s biggest international moments don’t end when the final out is recorded — they ripple forward into exactly the kind of behind-the-scenes conversations that shape how the game develops next.
It’s also worth noting how this fits into a broader pattern of the sport’s biggest figures staying involved in the game’s institutional development long after their moment in the spotlight has passed. Kuriyama could easily have stepped back from the day-to-day business of baseball after delivering Japan its WBC title, letting that achievement stand on its own as a career-defining accomplishment. Instead, he’s taken on an executive role with direct influence over player development at the Fighters, and he’s now using that platform to engage directly with a rival league’s leadership on exactly the kinds of structural questions — development pipelines, rule technology, national team strength — that will determine what international baseball looks like five or ten years from now. That’s a meaningfully different kind of legacy than simply being remembered for one incredible final out, even one as iconic as Ohtani versus Trout.
For Korean baseball specifically, hosting that kind of attention carries its own quiet significance. The KBO has spent recent years pushing forward on technological and structural experiments like ABS while also working to raise its international profile, sending increasing numbers of players toward MLB and building out its own national team program. A visit from someone with Kuriyama’s credentials — someone who’s proven, on the sport’s biggest international stage, that he knows what a genuinely competitive national program looks like — is the kind of external signal that tends to matter more than self-generated promotion. When the people running rival leagues start showing up to ask questions and compare notes, it usually means the answers are worth asking about.
