Imagine tuning into a high-stakes Yankees-Red Sox rivalry at Yankee Stadium, only to spot towering billboards in Japanese script flashing logos from Asics, Rakuten, or even a sake brewery like Hakkaisan. It’s not a glitch in the matrix—it’s just another day in Major League Baseball, where Japanese companies have carved out a prominent spot in the league’s visual landscape. If you’ve ever wondered why MLB’s backdrop feels like a subtle nod to Tokyo amid the roar of American crowds, you’re not alone. This phenomenon isn’t random; it’s a calculated fusion of cultural passion, economic savvy, and star power that’s reshaping the global game. In this post, we’ll dive into the “why” behind those eye-catching ads, explore their ripple effects, and hear from Japanese fans themselves. Whether you’re a die-hard Dodgers supporter or just curious about baseball’s international flair, stick around—this story bridges the Pacific like a grand slam.
The Roots: Baseball’s Deep Ties to Japan
Baseball didn’t just hop the ocean to Japan; it arrived with purpose. Introduced during the Meiji Restoration in the late 19th century, the sport quickly embedded itself in Japanese culture, becoming a symbol of modernization and resilience. By the 1930s, Nippon Professional Baseball (NPB) was thriving, with corporate-backed teams like the Yomiuri Giants turning games into communal rituals. Fast-forward to the post-World War II era, and MLB began eyeing Japan as a goldmine for expansion. Exhibition tours in the 1950s and ’60s drew massive crowds, but it was the 1995 defection of pitcher Hideo Nomo—dubbed “The Tornado”—that cracked the door wide open.
Nomo’s success wasn’t just personal; it sparked a player pipeline that’s now flooded with talent. Today, 12 Japanese-born players grace MLB rosters, from the New York Yankees’ Masahiro Tanaka to the Chicago Cubs’ Shota Imanaga.
But players alone don’t explain the ad blitz. Japanese corporations, many owning NPB teams themselves, have long viewed baseball as more than sport—it’s a branding powerhouse. In Japan, teams like the Hanshin Tigers aren’t profit-driven enterprises; they’re extensions of companies like Hanshin Electric Railway, designed to foster loyalty and visibility.
This mindset crossed the Pacific, turning MLB stadiums into billboards for global ambition.
The Economic Engine: Big Bucks for Big Reach
At its core, the surge in Japanese advertising boils down to cold, hard cash—and smart strategy. MLB games aren’t just American pastimes; they’re broadcast to over 2.2 million viewers in Japan per regular-season matchup, a 42% jump in recent years.
For brands like Mitsubishi UFJ or skincare giant Kose, that’s prime real estate to hawk everything from financial services to cosmetics to a worldwide audience. Stadium ads, especially those behind home plate, beam directly into living rooms across Asia and beyond, offering unmatched exposure.
Take the Los Angeles Dodgers as exhibit A. Since signing Shohei Ohtani in 2023, they’ve inked deals with over 12 new Japanese sponsors, raking in $70 million in extra revenue last year alone.
Ohtani’s “Shotime” magic—his unicorn status as a two-way phenom—hasn’t just boosted jersey sales (up 183% in Japan); it’s lured advertisers who follow him like groupies.
When Ohtani was with the Angels, 22 Japanese brands snapped up backstop ads for his at-bats; 11 more trailed him to away games.
The Dodgers even ran out of ad space so fast that sponsors started buying into opponents’ stadiums. It’s a win-win: MLB teams pocket millions, while Japanese firms tap into the U.S. market’s $20 trillion economy without building from scratch.
This isn’t new—Hideki Matsui’s 2003 arrival with the Yankees triggered a similar wave, with companies like Yomiuri forming joint ventures and pouring $6 million annually into ads.
But Ohtani’s era has supercharged it. Events like the 2025 Tokyo Series at Tokyo Dome—featuring the Dodgers against the Cubs—generated $35 million in tickets and sponsorships, plus $40 million in merch.
For international audiences, this underscores MLB’s pivot eastward: sustainable partnerships, from youth programs like MLB Dream Cup to digital content hubs tracking Japanese stars.
It’s not just ads; it’s ecosystem-building.
The Human Element: Japanese Fans’ Pride and Perspectives
From Tokyo to Osaka, Japanese baseball aficionados don’t just watch MLB—they live it. Social media buzzes with fervor during World Series runs, often eclipsing NPB’s Japan Series in conversation.
Fans like those on Reddit’s r/NPB subreddit gush over Ohtani not as a Dodger, but as a national icon—his games draw pilgrimage-level travel, with 1.2 billion yen spent by visitors last season.
One user recalled spotting Japanese ads at Chase Field during a Diamondbacks series: “It’s obvious—brands know half of Japan tunes in.”
Yet perspectives vary. Pride swells when stars like Roki Sasaki post for MLB; as one fan noted, “Fans should feel honored to see our talent conquer the world—it’s not selfish to dream big.”
But there’s quiet envy too. NPB’s corporate model, focused on ads over reinvestment, leaves some feeling the domestic league lags.
“It’s bittersweet,” shared a Marines supporter on X about Sasaki’s move. “We lose our best, but MLB elevates Japanese baseball globally.”
Culturally sensitive to these tensions, MLB treads lightly—promoting unity through events like Japanese Heritage Nights, blending respect for NPB’s “wa” (team harmony) with the allure of American individualism.
For everyday viewers, those ads evoke home. A Washington State University study found Japanese students watching broadcasts responded strongly to home-plate signage from brands like Dandy House, boosting recall by tying products to national heroes.
It’s empowering: In a globalized world, seeing your brands on Yankee Stadium’s facade whispers, “We’re here too.”
The Bigger Picture: A Global Game in Flux
This Japanese influx signals MLB’s maturation as a worldwide league. Sponsorship revenue from Japan spiked 114% in 2024, fueling everything from stadium upgrades to international broadcasts.

But it’s reciprocal—U.S. firms like Fanatics are eyeing Japan’s trading card market, projected to hit nine figures.
As climate and travel costs rise, virtual activations and apps tailored for Japanese users will likely deepen this bond.
Critics, though, flag risks: Over-reliance on one market could dilute local flavors, and the posting system—NPB’s transfer mechanism—still draws “slave auction” barbs for favoring teams over players.
Yet, as historian Nobby Ito puts it, “Losing stars isn’t all negative—it inspires NPB kids and pushes growth.”
For an international crowd, this evolution feels inclusive, honoring baseball’s universal language while respecting cultural nuances.
