KYOJO CUP 2025 Season Summary

For the first time in the KYOJO series' eight-year history, the Japanese all-female rookie racing series, held mostly at Fuji Speedway, was transitioned from prototype racing to formula racing.

The decision to switch to formula racing stems from growing concerns about the participation of Japanese women in motorsport. Since the cancellation of the now-defunct W Series' Japanese leg—originally scheduled to take place alongside the F1 Japanese Grand Prix three years ago—there have been increasing worries that the ongoing F1 Academy series may not feature a Japanese driver or might not be held during next season's Japanese Grand Prix and in the foreseeable future. 

Given these circumstances, the organisers of KYOJO felt that transitioning to formula racing was their only option. This move serves as an opportunity to send a message to the motorsport world: female drivers in Japan, whether local or foreign, deserve a chance to be part of all-female racing events.

The formula machine used in the 2025 KYOJO series, codenamed KC-MG01, is equipped with a turbocharged 1.4-liter engine that generates 176 horsepower. It also features a 12 kW hybrid system and is paired with a Sadev 6-speed paddle-shift transmission. The vehicle adheres to FIA F4 regulations regarding performance. In terms of suspension, it utilizes a double wishbone design with pushrods and adjustable anti-roll bars. The braking system is comprised of AP Racing 2-piston radial mount calipers and ENDLESS brake pads. Additionally, the car is outfitted with OZ Racing wheels and Bridgestone racing tires.

The 2025 KYOJO CUP season is packed with new and returning faces in the grid. A few foreign drivers are joining in the action, such as popular Asian-American racer and content creator, Hana Burton, as well as Thailand's Sitarvee Limnantharak, China's Zhao Yun Qing, and Kelsey Pinkowski from the United States.

The 2025 season kicked off last May 10-11 as a support race alongside the Inter Proto Series for Rounds 1, 3, and 5. Rounds 2 and 4 were support races that took place within the Super Formula 2025 season calendar.

Winning four out of five races, Rio Shimono, the driver of the #86 Dr.Dry with Team IMPUL KC-MG01, emerged as the 2025 season champion, holding her head high. In Round 2, Miki Onaga secured victory over Aimi Saito and Shimono.

With the successful transition of the KYOJO CUP from the VITA-01 to the KC-MG01, this Japanese all-female racing series has sent a strong message to the world: female drivers in Japan, whether local or foreign, deserve opportunities to participate in all-female racing events, particularly in the F1 Academy. While there's still more to achieve, we hope that the 2026 season will bring even more excitement to the new era of KYOJO.
