Why Major League Baseball keeps coming back to Japan
Major League Baseball’s long-standing relationship with Japan was highlighted during the Tokyo Series in March 2025, featuring the Dodgers and Cubs. The event generated significant revenue and broke viewership records. Japanese players, like Ichiro Suzuki and Shohei Ohtani, have boosted MLB’s global presence, indicating successful international investment.
Why Major League Baseball keeps coming back to Japan
When Shohei Ohtani stepped onto the field at the Tokyo Dome in March 2025, he wasn’t just playing a game – he was carrying forward more than 100 years of baseball ties between the U.S. and Japan.
That history was front and center when the Los Angeles Dodgers and Chicago Cubs opened their 2025 regular season facing off in the Tokyo Series on March 18 and 19. The two games featured severalplayersfromJapan, capping a slate of events that included four exhibition games against Japanese professional teams.
Baseball, which is by far the most popular sport in Japan, was introduced to the nation during the Meiji Restoration in the late 19th century.
American baseball promoters were quick to see the potential of the Japanese market, touring the country as early as 1908. The most famous such tour took place in 1934 and featured a number of American League All-Stars, including Babe Ruth and catcher Moe Berg, who was later revealed to be a U.S. spy.
That trip had a long legacy. The U.S. All-Stars faced a team called The Greater Japan Tokyo Baseball Club, which, a year later, barnstormed in the United States. When they played the San Francisco Seals, the Seals’ manager, Lefty O’Doul – who later trained baseball players in Japan – suggested a name change to better promote the team for an American audience.
Commenting that Tokyo is the New York of Japan, O’Doul suggested they take on one of their team names. And since “Yankee” is a uniquely American term, The Greater Japan Tokyo Baseball Club was reborn as the Tokyo (Yomiuri) Giants.
When the Giants returned to Japan, the Japanese Baseball League was formed, which was reorganized into Nippon Professional Baseball in 1950. The Giants have gone on to dominate the NPB, winning 22 Japan Series and producing Sadaharu Oh, who hit 868 home runs during his illustrious career.

Breaking into MLB
The first Japanese-born MLB player, Masanori Murakami, debuted for the San Francisco Giants in September 1964. But his arrival wound up sparking a contractual tug-of-war between the NPB and MLB. To prevent future disputes, the two leagues signed an agreement in 1967 that essentially blocked MLB teams from signing Japanese players.
By the 1990s, this agreement became untenable, as some Japanese players in NPB became frustrated by their lack of negotiating power. After the Kintetsu Buffaloes refused to give Hideo Nomo a multiyear contract after the 1994 season, his agent found a loophole in the “voluntary retirement clause” that would allow him to sign with an MLB franchise. He signed with the Los Angeles Dodgers in February 1995.
Nomo’s impact was immeasurable. His “tornado” windup and early success made him one of the most popular players in the major leagues, which was recovering from the cancellation of the World Series the previous year. In Japan, “Nomo fever” took hold, with large crowds gathering television screens in public to watch him play, even though his games aired in the morning. Nomo helped drive Japanese sponsorship and television rights as his first season ended with him winning National League Rookie of the Year.
But within a few years, disputes over contracts soon showed the need for new rules. This ultimately led to the establishment of posting rules for NPB players looking to transition to the major leagues.
The rules have shifted some since they were set out in late 1998, but if a player declares their intention to leave NPB, then MLB teams have a 45-day window to negotiate. If the player from NPB is under 25 or has less than nine years of professional experience, they’re subject to the limited MLB signing pool for international players. Otherwise, they’re declared a free agent.
A wave of stars
The new rules led many more Japanese players to join major league baseball from Nippon Professional Baseball: Of the 81 Japanese players who’ve played in the majors, all but four played in NPB before their debut. Ichiro Suzuki, who became the first Japanese player inducted into the National Baseball Hall of Fame, was also the first Japanese position player to make the leap.
Other players, like Hideki Matsui, the only Japanese player to be named World Series MVP, continued the success. And then came Ohtani, a two-way superstar who both hits and pitches, drawing comparisons to Babe Ruth.
For MLB, Japanese players haven’t just boosted performance on the field – they’ve expanded its global fan base. The Dodgers brought in over $120 million in increased revenue in Ohtani’s first year alone, easily covering his salary even with Ohtani signing the richest contract in baseball history. The franchise has also seen its value increase by at least 23% to nearly $8 billion. MLB has also seen a significant increase in viewership over the past two seasons, partially driven by the growing interest from Japan.
As American sports leagues deal with an increasingly distracted, fragmented domestic audience, it’s not surprising that they’re looking abroad for growth. And as MLB teams prepare to court another wave of Japanese stars this offseason, it’s clear that its decades-long investment in Japan is paying off.

How the explosion of prop betting threatens the integrity of pro sports
Miami Heat guard Terry Rozier was among 34 individuals arrested in connection with federal investigations into illegal gambling, highlighting a growing concern in sports. Prop bets, which allow wagering on specific game outcomes, have become prevalent, increasing the risk of corruption and match-fixing. The global sports betting market is expanding rapidly, raising alarms about integrity in sports.
When I first heard about the arrests of Portland Trail Blazers coach Chauncey Billups, Miami Heat guard Terry Rozier and former NBA player Damon Jones in connection to federal investigations involving illegal gambling, I couldn’t help but think of a recent moment in my sports writing class.
I was showing my students a clip from an NFL game between the Jacksonville Jaguars and Kansas City Chiefs. Near the end of play, Jaguars quarterback Trevor Lawrence threw a perfect pass to receiver Brian Jones Jr. to secure a critical first down. Out of the blue, a student groaned and said that he’d lost US$50 on that throw.
I thought of that moment because it revealed how ubiquitous sports betting has become, how much the types of bets have changed over time, and – given these trends – how it’s naive to think players won’t continue to be tempted to game the system.
The prop bet hits it big
I’ve been following the evolution of sports gambling for about a decade in my position as chair of Penn State’s sports journalism program.
Back when legal American sports betting was mostly confined to Las Vegas, the standard bets tended to be tied to picking a winner or which team would cover a point spread.
But ahead of the 1986 Super Bowl between the Chicago Bears and the overmatched New England Patriots, casinos offered bets on whether Bears defensive lineman – and occasional running back – William “Refrigerator” Perry would score a touchdown. The excitement around that sideshow kept fan interest going during a 46-10 blowout.
Perry did end up scoring, and the prop bet took off from there.
Prop bets are wagers that depend on an outcome within a game but not its final result. They can often involve an athlete’s individual performance in some statistical category – for instance, how many yards a running back will rush for, how many rebounds a basketball center will secure, or how many strikeouts a pitcher will have. They’ve become routine offerings on sports betting menus.
For example: As I write this, I am looking at a FanDuel account I opened years ago, seeing that, for the Green Bay Packers-Pittsburgh Steelers game currently in progress, I can place a wager on which player will score a touchdown, how many yards each quarterback will throw for and much, much more. As the game progresses, the odds constantly shift – allowing for what are called “live bets.”

Returning to my student who lost the bet on Lawrence’s pass completion: It’s possible he’d placed a bet on Lawrence to throw fewer than a set number of yards. Or he could have been part of a fantasy league, which is also dependent on individual player performances.
Either way, a problem with prop bets, from an anti-corruption perspective, is that an individual can often control the outcome. You don’t need a group of players to be in on it – which is what happened during the infamous Black Sox Scandal, when eight players on the Chicago White Sox were accused of conspiring with gamblers to intentionally lose the 1919 World Series.
In the indictment against him, Rozier is accused of telling a co-defendant to pass along information to particular bettors that he planned to leave a March 2023 game early – a move everyone involved knew meant he would not reach his statistical benchmarks for the game. They could then place bets that he wouldn’t hit those marks.
In baseball, meanwhile, Luis Ortiz of the Cleveland Guardians was placed on leave during the 2025 season and is under investigation for possibly illegally wagering on the outcome of two pitches he threw. MLB authorities are essentially trying to determine if he deliberately threw balls as opposed to strikes in two instances. (Yes, prop bets have become so granular that you can even bet on whether a pitcher will throw a ball or a strike on an individual pitch.)
An exploding market with no end in sight
The popularity of prop bets feeds into a worldwide sports gambling industry that has experienced explosive growth and shows no sign of slowing.
The leagues and media are more than just bystanders. FanDuel and DraftKings are official sports betting partners of the NBAand the NFL.
In the days after the Supreme Court ruling, I wondered whether journalists would embrace sports betting. These days, ESPN not only has a betting show, but it also has a betting app.
But those figures don’t begin to touch the worldwide sports betting market, especially the illegal one. The United Nations, in a 2021 report, reported that up to $1.7 trillion is wagered annually in illegal betting markets.

The U.N. report warned that it had found a “staggering scale, manifestation, and complexity of corruption and organized crime in sport at the global, regional, and national levels.”
Who’s the boss?
In early October 2025, I attended a conference of Play the Game, a Denmark-based organization that promotes “democratic values in world sports.” Its occasional gatherings attract experts from around the world who are interested in keeping sports fair and safe for everyone.
One of the most sobering topics was illegal, online sportsbooks that feature wagering on all levels of sport, from the lowest levels of European soccer on up.
It sounded somewhat familiar. This summer at the Little League World Series, which my students covered for The Associated Press, managers complained about offshore sportsbooks offering lines on the tournament, which is played by 12-year-old amateurs.
And with so much illegal wagering in the world, the issue of match fixing was bound to come up.
One session screened a recent German documentary on match fixing. Meanwhile, Anca-Maria Gherghel, a Ph.D. candidate at Sheffield Hallam University and senior researcher for EPIC Global Solutions, both in northern England, told me how she had interviewed a professional female soccer player for a team in Cyprus. The player described how she and her teammates were routinely approached with lucrative offers to throw matches.
Put it all together – the vast sums of money at play and the relative ease of fixing a prop bet, let alone a match – and you cannot be surprised at the NBA scandal.
I used to think that gambling was just a segment of the larger sports industry. Now, I wonder whether I had it exactly backward.
Has sports just become a segment of the larger gambling industry?
From FIFA to the LA Clippers, carbon offset scandals are exposing the gap between sports teams’ green promises and reality
Under Steve Ballmer’s ownership, the LA Clippers have made strides in reducing greenhouse gas emissions, yet concerns arise over the efficacy of their carbon offsets, especially following issues with their partner, Aspiration. Many sports organizations face scrutiny for their offset claims, highlighting a need for transparent, verified carbon reduction strategies and a reassessment of sustainability practices in the industry.

If you go to a pro sports event today, there’s a good chance the stadium or arena will be powered at least in part by renewable energy. The team likely takes steps to reduce energy and waste. Some even claim to have net-zero greenhouse gas emissions, meaning any emissions they still do produce they offset by paying for projects, such as tree-planting, that reduce greenhouse gases elsewhere.
The venue upgrades have been impressive – Seattle’s hockey and basketball arena runs on 100% renewable energy, makes its rink ice from captured rainwater, and offers free public transit for ticket holders.
It’s an important question, in part because fans may ultimately pay for those offsets.Lionel Messi of Argentina controls the ball during the FIFA World Cup Qatar 2022 final match.

The cost of carbon offsetting in sports varies by organization, with no industry standard for who pays. Some teams and leagues absorb costs through their operational budgets, treating carbon neutrality as a core responsibility. Others pass costs to consumers: Some teams add sustainability fees to ticket prices to offset each attendee’s carbon footprint. The payment model ultimately reflects whether an organization views offsetting as an institutional obligation or a shared responsibility with fans.
The vast majority of a sports team’s climate footprint comes from team’s and fans’ travel, which they have little control over. Leagues can reduce teams’ travel somewhat with creative scheduling, but unlike other industries, sports teams have few ways to reduce the bulk of their emissions.
What many of them do instead is offset those travel emissions by buying carbon credits.
Carbon credits are generated by projects that reduce greenhouse gases in the atmosphere or prevent greenhouse gas emissions. Many of those projects involve planting trees to remove carbon dioxide from the atmosphere; others expand clean energy to reduce fossil fuel use. Each carbon credit is supposed to represent the reduction or prevention of one metric ton of carbon dioxide.
Unfortunately, several teams, perhaps unknowingly, have been purchasing fraudulent or low-quality credits.
Reputations at risk
FIFA brought the sports world’s carbon offset problem into the spotlight during the 2022 Qatar World Cup.
FIFA claimed the event would be carbon neutral, but that claim relied on creative accounting that understated the event’s construction and travel emissions. Organizers also used low-quality offsets. Many of those offsets were renewable energy projects with a high likelihood of being built anyway.
A year after the tournament, FIFA had completed offset purchases for less than a third of the World Cup’s estimated emissions, the nonprofit Carbon Market Watch found. And Switzerland’s advertising regulator ordered FIFA to stop claiming the World Cup had been “carbon neutral.”In 2022, the Boston Red Sox announced a plan to route a portion of the proceeds from every ticket purchased at Fenway Park to a carbon offset project run by Aspiration. Aspiration later went bankrupt, and a ProPublica investigation found it had planted far fewer trees to store that carbon than promised. Werner Kunz/Wikimedia Commons, CC BY-SA
The Clippers and baseball’s Boston Red Sox ran into problems when they publicly partnered with Aspiration, a now-bankrupt finance technology company and carbon credit broker, to meet their “carbon neutral” claims.
However, Aspiration officials claimed to have supported millions more tree-plantings than what had actually happened, a ProPublica investigation found. Aspiration co-founder Joe Sanberg pleaded guilty in 2025 to wire fraud involving false statements about financing to secure loans and attract investors, who lost at least $248 million.
The Aspiration partnership is also under investigation by the NBA over an endorsement deal the company made with Clippers all-star Kawhi Leonard at about the same time and questions about whether it was used to violate the league’s salary cap. Team owner Steve Ballmer, who personally invested at least $50 million in Aspiration, told ESPN he and the team did nothing wrong. “They conned me,” he said.
While the scandal focused on financial fraud and the salary cap, it also raised questions about the team’s sustainability claim.
Without verification, who knows?
In some cases, the value of offset projects is difficult to verify, even when trees are being planted nearby.
While the effort positioned the club as a sustainability leader, the offsets lacked what’s known as third-party verification. Similar to how organic food must be certified by reputable agencies, third-party validation of carbon credits ensures credits truly represent the removal of carbon from the atmosphere or avoided emissions.
Without verification, it’s unclear whether claimed emission reductions are permanent, accurately tracked and transparently reported.
Potential legal consequences
Even the most prominent venues are susceptible to issues with unreliable credits.

It represents one of the most ambitious pushes to develop sustainable sport infrastructure globally.Hockey rinks need energy to keep the ice frozen. Seattle’s Climate Pledge Arena has lowered its emissions with solar power from a local array and has even electried its Zambonis. But reports have raised questions about the quality of carbon offsets it purchased. AP Photo/Maddy Grassy
To offset unavoidable construction emissions, the arena’s owner relied on carbon credits tied to projects meant to reduce rainforest loss in Colombia. However, an analysis by the carbon rating company Calyx Global found that while the arena’s credits may prevent some deforestation, the numbers likely overstate the benefits.
Delta Air Lines, for example, is facing a lawsuit over its carbon neutrality claim. The suit alleges that Delta misled passengers by describing itself as a “carbon-neutral airline” while relying on carbon offset projects that were ineffective or “junk.”
To provide meaningful sustainability commitments, sports organizations and facilities can start at home by lowering their fossil fuel use and increasing their energy efficiency. Many arenas do this.
Where offsets will still play a role, teams can ensure that they partner with verified carbon credit providers that deliver measurable, transparent carbon reductions.
In a field where public trust and reputation matter as much as performance, the sports industry cannot afford foul play on climate. We believe a shift toward strategies that cut emissions first, and then use only the most credible offsets, will be the difference between striking out and leading the sustainability game.
George Plimpton’s ‘Paper Lion’ Exposed the Brutal Reality of NFL Training Camp in 1966
How writer George Plimpton went undercover as a Detroit Lions quarterback in 1963 and created the sports journalism classic ‘Paper Lion.’ Discover the bruising truths he revealed about NFL training camp and what separates fans from players.

George Plimpton’s 1966 nonfiction classic ‘Paper Lion’ revealed the bruising truths of Detroit Lions training camp
Stephen Siff, Miami University As the Detroit Lions barrel toward a Thanksgiving Day game with the Green Bay Packers, some die-hard fans may be fantasizing about what it would be like to be on the field themselves: calling plays from the Lions huddle, accepting the snap from between a crouching center’s thighs, and spinning to hand off the football before the defensive linemen come crashing down. In 1963, Lions head coach George Wilson allowed writer and Paris Review editor George Plimpton to enact that fantasy. With a Sports Illustrated contract in hand, Plimpton convinced Lions management to allow him to enter preseason training camp at Cranbrook, the private boys school in Bloomfield Hills, Michigan. His plan was to go undercover as a rookie quarterback for a magazine article that would reach dramatic culmination when he called a series of plays in a game of professional football. No one expected the amateur athlete to survive for long on a field with real-life Lions. But in writing about the experience, Plimpton turned off-field fandom and on-field bumbling into literary gold.Little, Brown reissued Paper Lion in 2016.Little, Brown His resulting 1966 book, “Paper Lion: Confessions of a Last-String Quarterback,” became a bestseller that was praised by The New York Times as “one of the greatest books written on sports, and the most thoroughly engaging book on any subject in recent memory.” A 1968 movie based on the book starred Alan Alda as Plimpton and members of the 1967 Lions team as themselves. Decades before I became a journalism professor at Miami University of Ohio, I discovered Plimpton’s sportswriting from reading the paperback versions I found on my parents’ bookshelves. Plimpton was a leading member of a mid-20th-century class of literary journalists, including Tom Wolfe, Truman Capote, Gay Talese and Norman Mailer, who were becoming known for applying novelistic techniques and sometimes personal, subjective perspectives to nonfiction. While the other literati tackled heavy topics, Plimpton’s engaging, conversational prose goofed around on the fringes of pro sports. Many of his books followed the same “participatory journalism” formula. He wrote about pitching against MLB all-stars, traveling with the PGA tour, boxing a bout against Archie Moore and playing with the Boston Bruins. Those were just the full-length books. Other television and magazine projects had Plimpton competing in tennis and bridge; performing stand-up comedy; acting in a Western; playing with the New York Philharmonic; and attempting to be an aerialist with the circus. However, he is best known for trying his hand quarterbacking for the Lions.
Posh writer meets the gridiron
In some ways, Plimpton seemed exactly the wrong person for this job. The possessor of a distinctively old money accent and patrician wealth and manners, he was founding editor of The Paris Review and in 1967 a mainstay of literary salons in Paris and New York. “Author, critic, interviewer, party-giver … friend of everybody, gifted, personable, energetic, bright, with-it, rich, a legend in his own time,” The New York Times gushed. Just the kind of person whom your average football fan might enjoy seeing knocked flat.American journalist and literary critic George Plimpton was no fan of pain, and that limited his ability on the football field.Evening Standard/Hulton Archive/Getty Images Plimpton joined a team he described as recovering from scandal. After ending the 1962 season with an 11-3 record and a Playoff Bowl victory for third place in the NFL, the NFL commissioner’s office fined six Lions for gambling on the championship game between Green Bay and New York. More significant on field, the commissioner suspended Lions great defensive tackle and future Pro Football Hall of Famer Alex Karras for one year. Without him, the Lions would end the 1963 season 5-8-1. Plimpton wrote his way onto the team by promising to “just hang around on the periphery of things and not bother anyone, just try to participate enough to get the feel of things.” Wilson agreed, and Plimpton arrived at training camp a few months later with his own football, purchased from an army-navy store in Times Square, and a “mild fiction” about having played quarterback at Harvard and for the nonexistent Newfoundland Newfs. Plimpton’s attempt at deception might raise ethical questions; however, the joke is always on him. The coaching staff seemed to have thought it would be hilarious if anyone on the team actually took the gangly 36-year-old with the nasal accent as a professional football player. It seems unlikely that anyone did. “I never had the temerity to pretend I was something that I wasn’t,” Plimpton wrote. “The team caught on quickly enough.” At camp, Plimpton hung around the dining hall and sat in the back of team meetings. A master of small talk, he lets the reader eavesdrop on conversations with Hall of Famers Karras, Dick “Night Train” Lane and Joe Schmidt. Plimpton takes us with him one night to a bar frequented by coaches, where we listen in rounds of liars’ poker with Wilson, Scooter McLean and Les Bingaman. We tag along as he chats with Karras at Lindell’s A.C., the bar the player owned in downtown Detroit at the time.
Lessons in grit
At training camp, Plimpton faced the teasing of players but earned respect by facing the brutality of sport and by persisting despite the inevitability of pain. He never played football in school, beyond a beery game between Harvard Crimson and Harvard Lampoon, and did not know the basics of playing quarterback. Several days into camp, he was allowed to participate in a play where, as quarterback, he was supposed to quickly hand off the ball to another player. “At ‘two’ the snap back came,” Plimpton wrote. “I began to turn without the proper grip on the ball, moving too nervously, and I fumbled the ball, gaping at it, mouth ajar, as it fell and bounced twice, once away from me, then back, and rocked back and forth gaily at my feet. I flung myself on it (…) and I heard the sharp strange whack of gear, the grunts, and then a quick sudden weight whooshed the air out of me.” The same thing happened when Plimpton was allowed to take the field in an annual intra-squad game played in Pontiac. Over his first three plays he lost 20 yards by falling down, getting knocked over by his own teammates and being literally picked from the ground by a zealous defender. On the bus ride home, Plimpton admitted to Wilson that he didn’t like being hit. The coach gently explained that “love of physical contact” was necessary to make it in pro football. “When kids, out in a park, chose of sides for tackle rather than touch, the guys that want to be ends and go out for the passes, or even quarterback, because they think subconsciously they can get rid of the ball before being hit, those guys don’t end up as football players,” Wilson mused. “They become great tennis players, or skiers, or high jumpers. It doesn’t mean they lack courage or competitiveness.” “But the guys who put up their hands to be tackles or guards, or fullbacks who run not for daylight but for trouble – those are the ones who will make it as football players.” This quality of great football players – an irrational enthusiasm for bruising physical contact – is celebrated by Plimpton in the veteran Lions who take him into their orbit. He becomes friends with Karras and offensive lineman John Gordy, in particular, and shoots the breeze on topics ranging from the NFL commissioner to Adolf Hitler. In a subsequent book, Plimpton goes with the pair to a madcap golf tournament and starts a ridiculous business venture, suggesting the on-field madness necessary to succeed in football bleeds into off-field life as well. But it is not Plimpton’s way to delve into the psychology of his idols. Rather, he listens as they spin tales that show how reckless the grown men who run toward trouble really are.Stephen Siff, Associate Professor of Journalism, Miami University
