Super Mario Bros. 40th Anniversary Celebration Hits Japanese Baseball with Nintendo-Themed Showdown
Wednesday, April 29, 2026 | Chiba, Japan
CHIBA, Japan — The iconic plumber who once leapt across 8-bit landscapes has now vaulted into Japan’s professional baseball stadiums. On Wednesday, all 12 teams of Nippon Professional Baseball (NPB) will celebrate the 40th anniversary of Super Mario Bros. with a league-wide event dubbed “Super Mario Bros. 40th Anniversary × Pro Baseball 12 Teams,” transforming ballparks into pixelated playgrounds for one day only.
At Chiba Marine Stadium, home of the Chiba Lotte Marines, the festivities will culminate in a live Mario Kart World showdown between two of the team’s rising stars: catcher Tora Matsukawa and infielder Takanari Terachi. The race, scheduled for the break between the third and fourth innings, promises to blend Nintendo nostalgia with Japan’s beloved pastime in a spectacle unseen in the league’s history.
The Event: What’s Happening and Why It Matters
The collaboration between Nintendo and NPB marks the first time the gaming giant has partnered with an entire professional sports league for a single-day celebration. While individual teams have previously hosted gaming-themed nights—including esports tournaments and retro game giveaways—this event is unprecedented in its scale and coordination.
Verified Details of the Celebration
- Date and Time: Wednesday, April 29, 2026, with games starting at 6:00 PM JST (9:00 AM UTC) across all 12 NPB stadiums. The Mario Kart race at Chiba Marine Stadium is slated for approximately 7:30 PM JST (10:30 AM UTC).
- Teams Involved: All 12 NPB teams, including the Chiba Lotte Marines, Yomiuri Giants, Hanshin Tigers, and Hokkaido Nippon-Ham Fighters. Each stadium will feature team-specific Nintendo-themed activities, though the Mario Kart race is exclusive to Chiba.
- Special Merchandise: The Chiba Lotte Marines’ online store is selling limited-edition Super Mario Bros. 40th-anniversary merchandise, including caps, towels, and apparel featuring the team’s colors alongside Mario and Luigi. A portion of proceeds will benefit local youth baseball programs, per the team’s official announcement.
- Attendance Giveaways: The first 28,000 fans at Chiba Marine Stadium will receive a commemorative color poster signed by pitcher Roki Sasaki and catcher Tora Matsukawa, celebrating Sasaki’s 2023 perfect game. Additional Nintendo-themed giveaways are planned at other stadiums, though specifics vary by team.
Why This Event Is a Huge Deal
The partnership underscores the growing intersection of gaming and sports, a trend accelerated by the pandemic and the rise of esports. For Nintendo, the event is a rare foray into live sports marketing, leveraging Super Mario Bros.’s cultural ubiquity to engage fans beyond traditional gaming demographics. For NPB, it’s an opportunity to attract younger audiences and international attention, particularly ahead of the 2026 Asian Games, where baseball will be a featured sport.
“This is more than just a gimmick,” said Dr. Hiroshi Aoyama, a sports marketing professor at Waseda University, in an interview with Nikkei Sports. “It’s a strategic move to position NPB as a forward-thinking league that embraces pop culture. The timing is perfect, given the global resurgence of retro gaming.”
The Stars of the Show: Matsukawa and Terachi’s Mario Kart Duel
The centerpiece of Chiba’s celebration is the Mario Kart World race between Tora Matsukawa, the Marines’ 21-year-old catcher, and Takanari Terachi, a 23-year-old infielder known for his speed and clutch hitting. The two players, both rising stars in Japan’s baseball scene, will compete on a custom track designed to resemble Chiba Marine Stadium, with the live feed broadcast on the stadium’s giant screen.
Who Are the Competitors?
Tora Matsukawa (#2)
Position: Catcher | Age: 21 | 2026 Season Stats (as of April 28): .287 BA, 4 HR, 15 RBI
Matsukawa, a product of the Marines’ youth academy, made his NPB debut in 2023 and quickly established himself as one of the league’s most promising young catchers. Known for his defensive prowess and leadership behind the plate, he was a key figure in Roki Sasaki’s historic perfect game in 2023. Off the field, Matsukawa is an avid gamer, often streaming his Mario Kart sessions on social media.
Takanari Terachi (#65)
Position: Infielder (Utility) | Age: 23 | 2026 Season Stats (as of April 28): .253 BA, 3 HR, 12 RBI, 5 SB
Terachi, a switch-hitter with elite speed, has been a revelation for the Marines since his debut in 2024. His versatility—he can play second base, shortstop, and third base—has made him a valuable asset for manager Masato Yoshii. Like Matsukawa, Terachi is a self-proclaimed Nintendo fan, though he’s never publicly revealed his Mario Kart skills.
What to Expect from the Race
The Mario Kart World race will feature a three-lap sprint on a track designed to mimic Chiba Marine Stadium, complete with pixelated versions of the outfield walls and the team’s mascot, Marine-kun. The players will use standard Nintendo Switch controllers, with the race broadcast on the stadium’s main screen and streamed live on the Marines’ official YouTube channel.
While the event is lighthearted, both players have expressed competitive spirits. In a press conference on Tuesday, Matsukawa joked, “I’ve been practicing for this since I was a kid. I won’t let Terachi win easily.” Terachi, meanwhile, played it cool: “I’m just here to have fun. But if I win, I’m expecting a lot of bragging rights.”
The winner will receive a custom trophy designed by Nintendo, featuring a golden Mario Kart item box. The loser, per team tradition, will have to wear a Luigi-themed jersey during the team’s next practice.
How the Event Fits Into NPB’s Broader Strategy
The Super Mario Bros. celebration is part of a larger effort by NPB to modernize its fan engagement strategies. In recent years, the league has experimented with:
- Esports Collaborations: NPB launched its own esports league in 2023, featuring virtual versions of its teams competing in games like eBaseball Powerful Pro Yakyū and Pro Evolution Soccer.
- International Expansion: The league has increased its English-language broadcasts and partnered with MLB to promote Japanese players in the U.S., including high-profile signings like Shohei Ohtani and Yoshinobu Yamamoto.
- Youth Outreach: Teams like the Marines have expanded their youth academies, offering free clinics and gaming-themed events to attract younger fans.
“This event is about bridging generations,” said NPB Commissioner Atsushi Saito in a statement. “For older fans, it’s a nostalgic trip down memory lane. For younger fans, it’s a chance to see their favorite players in a new light. And for Nintendo, it’s an opportunity to introduce Super Mario Bros. to a whole new audience.”
What’s Next for the Chiba Lotte Marines?
The Marines enter Wednesday’s game against the Hokkaido Nippon-Ham Fighters with a 14-10 record, decent for third place in the Pacific League standings. The team’s pitching staff, led by ace Roki Sasaki (3-1, 2.15 ERA in 2026), has been a bright spot, but the offense has struggled with consistency.
Tonight’s game is the second in a three-game series against the Fighters, who are coming off a sweep of the Saitama Seibu Lions. A win would keep the Marines within striking distance of the league-leading Fukuoka SoftBank Hawks, who hold a two-game lead.
After tonight’s Nintendo-themed festivities, the Marines will travel to Sapporo for a three-game series against the Fighters starting May 2. The team’s next home game is scheduled for May 5 against the Orix Buffaloes.
