Rio Shimono is a Japanese racing driver who made history as the first female competitor in TCR Japan and later became one of the most dominant forces in Kyojo Cup history, clinching the 2025 championship with an astonishing eight wins from ten races.

EARLY YEARS

Born May 25, 2000, in Osaka, Japan, Rio Shimono’s path to motorsports remains largely undocumented in her early years. What we do know is that by age 19, she was already making her mark on Japanese racing circuits, suggesting a determined climb through the karting ranks that hasn’t been publicly chronicled. Her hometown of Osaka—a city known for its hustle and innovation—perhaps foreshadowed the kind of driver she’d become: scrappy, strategic, and unafraid to enter spaces where women weren’t expected.

OTHER INTERESTS

Like many professional racers who keep their focus laser-sharp on the track, Rio keeps her off-track life firmly out of the spotlight. No public hobbies, no Instagram-friendly side hustles, no carefully curated personal brand. For Rio, the racing appears to speak for itself—and honestly, when you’re winning eight out of ten races in a season, who needs a hobby?

EARLY SUCCESS

Shimono’s competitive debut came in 2019 with Drago Corse in the Super-FJ Suzuka Series and Autopolis Series. While the Suzuka campaign yielded an 11th-place finish across six races, the Autopolis Series showed what she was capable of: one win and fifth overall with 30 points from just three races. It was a glimpse of the consistency and pace that would define her later career.

The real breakthrough came in 2020 when Rio made history as the first female driver to compete in TCR Japan. Driving a Honda Civic for Drago Corse, she didn’t just show up—she won. Taking the Bronze class championship in the Saturday Series with one victory, one pole position, and second overall with 81 points, Rio proved she belonged in touring car racing’s competitive landscape. She also managed two podiums in the Sunday Series, finishing fourth overall. The season should have been a pure celebration, but the coronavirus outbreak delayed the series and added an extra layer of challenge to an already demanding rookie campaign.

It was during this 2020 season that Rio developed a friendship with Tatiana Calderon, the Colombian driver who was competing in Super Formula with Drago Corse. The connection between two women navigating Japan’s male-dominated racing scene offered mutual support in an environment where female competitors remained rare.

NOTABLE ACHIEVEMENTS

• 2019: Won one race in Super-FJ Autopolis Series with Drago Corse, finishing fifth overall.
• 2020: Became first female driver to compete in TCR Japan touring car series.
• 2020: Won TCR Japan Saturday Series Bronze class championship with Drago Corse, securing one win and one pole position.
• 2021: Finished third overall in Kyojo Cup with Drago Corse, earning two podium finishes.
• 2022-2024: Competed in F4 Japanese Championship across three seasons with Zap Speed and Dr. Dry, showing steady improvement with top-ten finishes including ninth at Motegi in 2024.
• 2025: Dominated Kyojo Cup with Itochu Enex Wecars Team Impul with Dr. Dry, winning eight of ten races to claim the championship—one of the most successful campaigns in series history.
• 2025: Finished third in F110 Cup with Dr. Dry Racing Team with one podium from two races.

INSPIRATIONS

Rio hasn’t publicly shared the drivers, moments, or influences that drew her to racing. Whether that’s a cultural preference for letting results do the talking or simply a private personality, we’re left to read between the lines. Her connection with Tatiana Calderon suggests she values the camaraderie of fellow female racers navigating similar challenges, but beyond that, Rio’s inspirations remain her own.

REPUTATION

Within Japanese motorsports circles, Rio Shimono has earned recognition not for flash or drama, but for calculated aggression and technical growth. Her multi-discipline experience—touring cars, Formula 4, single-seater categories—has built a driver with adaptability and racecraft. Dr. Dry’s decision to promote her to Formula Regional Japan for 2026 speaks volumes about how she’s regarded within her team: a driver with the consistency and race management skills to handle the next level.

Her 2025 Kyojo Cup dominance—eight wins from ten starts—established her as one of the series’ most successful drivers in history. The media coverage focuses on her steady progression and work ethic rather than any single spectacular moment, which feels entirely fitting for a racer who’s built her career on accumulating points and podiums rather than headlines. With a career tally of 54 races entered, one overall win, four podiums, and three pole positions, Rio’s statistics reflect a driver still building momentum rather than resting on past glory.

FUTURE GOALS/PLANS

Rio enters 2026 with a promotion to Formula Regional Japan with Dr. Dry—a significant step up the single-seater ladder and a vote of confidence from a team that’s watched her develop across multiple campaigns. She’ll also return to defend her Kyojo Cup title, giving her a dual-series program that tests both her advancement in formula racing and her ability to maintain dominance in a category she’s already conquered. It’s an ambitious schedule that reflects either serious career momentum or a calculated decision to keep building experience across disciplines. Knowing Rio’s track record, probably both.
