Japanese F4 enters its 12th season at Fuji this weekend with 54 drivers entering across two classes. This year’s grid features both the youngest and the oldest driver in the series’ history and the oldest driver Feeder Series ever reported on. Feeder Series tells you everything you need to know about the 2026 season. 

By Finjo Muschlien

Eight manufacturer-backed drivers will be on this year’s grid in a series that has had 11 champions all backed by either Honda or Toyota. But for much of last year, this streak seemed set to come to an end. Kageyama Racing’s Itsuki Sato led the drivers’ championship until the final round, when car issues and a collision with his rival and eventual champion Tokiya Suzuki – followed by a controversial penalty – allowed the Toyota junior to take the title. 

The series uses the Toray Carbon Magic MCSC-24 with a TOM’S TMA43 engine. The combination was first introduced in 2024 as the series’ second-generation car package.

The calendar

The calendar consists of seven rounds with two races per class each. The series makes its first visit to Okayama since 2019, and that event will be the only time this year the championship supports Super Formula Lights rather than Super GT. 

Round 1: Fuji Speedway (1–4 May)

Round 2: Okayama International Circuit (11–14 June)

Round 3: Fuji Speedway (29 June–2 August)

Round 4: Suzuka Circuit (20–23 August)

Round 5: Sportsland Sugo (17–20 September)

Round 6: Autopolis International Racing Course (15–18 October)

Round 7: Mobility Resort Motegi (5–8 November)

The format

Japanese F4 splits its grid into two classes: the Champion Class for younger drivers and the Independent Class for gentlemen drivers. The standings run in separate ecosystems. Three class-separated practices take place across Thursday and Friday ahead of each weekend. Saturday morning sees one qualifying session for each class that sets the grid for the first races, while the second-fastest times set the grids for the second races. 

Having tested a new format of races split by class in two rounds over the past two years, the series will continue with this format, with both classes racing separately twice.

The series uses the standard FIA points format, with no bonus points for pole positions or fastest laps. 

Where to watch

All races are streamed on the series’ official YouTube channel. Live timing will be available on the Super GT Live Timing app, although it is not available in Europe.

Teams and drivers

Skill Speed is the only team not returning to the championship this year. Drago Corse is expected to return later in the year with Kaoru Yoshida (#34), who made his Japanese F4 debut in the Sugo round last year with Ragno Motor Sports. M&K Racing and driver Mitsuhiro Endo (#97), as well as the one-car Team Le Mans, are also expected to race later this year. 

All teams and drivers are Japanese unless otherwise noted.

Kageyama Racing

It took 11 years, but last year, Kageyama Racing – owned by 1993 Japanese Touring Car champion Masahiko Kageyama – became the first team not backed by Toyota or Honda to clinch a teams’ title in Japanese F4. Their driver Itsuki Sato was also the championship leader for the majority of the season, but he missed out on the title after experiencing misfortune in the final round at Motegi.

Kageyama fields two returning drivers this year. One is 17-year-old Ryusho Nakazato (#15), who joined the team from the second round of last year’s season onwards and came 27th in the standings with a best result of 14th. He is one of very few drivers to have competed in a championship during the winter, racing in UAE4 with Pinnacle Motorsport and coming 36th overall.

The other returnee, Ryo Shirasaki (#16), enters his third full season of Japanese F4 this year and his second with Kageyama. The 27-year-old’s first with the team was a success, as he took three wins en route to third in the drivers’ championship, which helped the team clinch the teams’ championship. Shirasaki is the 2023 Super FJ Suzuka Okayama Series champion.  

With Sato leaving, Kageyama had a mammoth task to replace him, and the team have opted for Yuta Suzuki (#17). The 17-year-old made his F4 debut last year in the F4 Middle East Championship, in which he came 22nd overall, before entering Japanese F4 with Drago Corse, in which he came 17th with a best result of seventh. Suzuki is the 2024 GPR Karting Series champion in the shifter class. 

Yutaka Toriba (#18) will be the team’s only driver in the Independent Class this year. The 62-year-old won the Independent Class in 2022, racing for Helm Motorsports, and he also became last year’s masters’ champion in FRegional Japan racing for Aiwin, with whom he continues to race in the championship this year. Besides F4 and FR, Toriba is actively competing in historic racing, driving Williams’ 1981 F1 championship-winning car, the Williams FW07C.

TGR-DC Racing School

Eight of the 11 champions in Japanese F4 thus far have been Toyota juniors, driving for the TGR-DC Racing School squad or its predecessor, TOM’S Spirit. This year, the de facto Toyota junior team fields six drivers, with two of them returning and four entering their first season in the championship following their participation in the Toyota Racing School shootout as was the case last year. 

Their higher-placed returnee is Yuzuki Miura (#28), who enters his second season in Japanese F4. Miura came 12th in the championship last year and took one podium finish. The 19-year-old was the second-highest-placed rookie of TGR-DC RS last year. He is also competing in FR Japan with TOM’S this year and is leading the drivers’ championship with two wins in three races after the first round. He also made his SF Lights debut at Autopolis last weekend, replacing Tokiya Suzuki, who was stood down by TOM’S. 

Masana Muto (#29) likewise enters his second season in Japanese F4 after coming 15th in the standings with a third-place finish last year. Like Miura, the 17-year-old competes in FR Japan with TOM’S, and he currently sits fourth in the standings with one podium after the opening round. 

The 2024 GPR karting series OK class champion, Ryo Sakai (#35) will enter his first season in Japanese F4 as a Toyota junior, but it will not be his first in single-seaters. Last year, as a result of winning the GPR karting series, he received a scholarship to compete in the F110 Cup with KF Motorsport, ending the season second in the drivers’ standings with one win. 

Masaki Hamabe (#36) likewise isn’t a single-seater debutant, as he brings three years of Super FJ experience ahead of his Japanese F4 debut. The 18-year-old came ninth in the series’ Japan League standings last year. Notably, Hamabe only competed in rental karts before he switched to cars. 

Buntaro Igarashi (#37) also competed in Super FJ last year with Drago Corse. The 18-year-old won the 2022 JAF Regional Karting Championship Motegi series in the FS-125 class in 2023 and also competed in the All-Japan Karting Championship’s OK class, finishing fifth. 

TGR’s only single-seater debutant will be Tomoki Terashima (#38), who last competed in the Rotax Asia Trophy in 2025. The 18-year-old won the all-Japan karting series in 2024, and his grandfather opened the now family-run Festika Mizunami karting circuit on which several of his rivals raced before stepping up to F4. 

B-Max Racing Team

B-Max Racing enter the championship with two teams, B-Max Engineering for their Champion Class and Independent Class drivers and HFDP with B-Max Racing Team for the two Honda juniors thanks to the team’s collaboration with the manufacturer. The team won the teams’ championship, and their driver Yuto Nomura won the drivers’ championship in 2024. B-Max is owned by Ryuji Kumita, who continues to race in the championship. 

Haruto Nakai (#42) makes the switch over from Helm Motorsports, with whom he made his F4 debut last year. The 17-year-old finished 20th in the Japanese F4 drivers’ standings, collecting two ninth-place finishes, but he was more successful in the F110 Cup with the team, as he came third overall with one win. Nakai won the FS-125 class of the JAF regional karting championship in 2024.

Seventeen-year-old Ryoki Minoura (#43) will enter his first Japanese F4 season, but not his first in single-seaters, as he steps up from Super FJ. In 2023, he won the JAF regional karting Suzuka championship and came third in the All-Japan karting championship’s FS-125 division. He was also part of the Honda Racing School in 2024. 

Syo Momose (#50) was likewise in 2024’s Honda Racing School, and although he did not win the scholarship, he became a Honda junior the following year. The 18-year-old made his Japanese F4 debut with B-Max Racing last year, coming sixth in the standings with two podium finishes. Momose won the all-Japan karting championship’s FS-125 class in 2021. 

Kazuma Kurosawa (#51) will be Honda’s other junior in Japanese F4 this year, having likewise taken part in the Honda Racing School last year but failed to win the scholarship. The 18-year-old will not be a single-seater debutant, though, as he received a scholarship to compete in the F110 Cup with Hammer Racing having won the virtual all-Japan e-F4 championship in 2024. He finished 15th in the standings.

Team owner Ryuji Kumita, better known under his pseudonym “Dragon” (#30) will enter his 10th season in Japanese F4. The 59-year-old won the Independent Class title as well as the SF Lights masters’ class title in 2024 but missed out on both accolades in 2025. As he did in previous years, Kumita will also compete in SF Lights alongside his F4 duties. 

Last year’s Independent Class champion Nobuhiro Imada (#44) will also return for 2026, remaining with B-Max. The 61-year-old likewise competes in SF Lights as well as in the Japanese and European Ferrari Challenge series. 

The team’s only full-time addition in the Independent Class this year is Yasuhiro Shimizu (#88), who made his debut in the championship in the final two rounds of last year, bagging one win. The 43-year-old won the masters’ class in SF Lights last year. He will be absent from the opening round.

Ponos Racing

Ponos Racing enter their fourth season in the championship this year. As was the case last year, the team field a driver who just lost the backing of one of Japan’s manufacturers despite showing promising results. The team is owned by Ponos CEO Yorikatsu Tsujiko, who is also a racing driver himself. 

Following a rather controversial decision, Toyota dropped their highest-placed rookie from last year from their roster. Instead, Megumu Suzuki (#45) will make the switch to Ponos Racing, filling the shoes of Ryota Horachi, who likewise joined the team after being ditched by Honda despite finishing second in the 2024 championship. The 17-year-old won the All-Japan karting championship’s FS-125 class in 2023.

Shota Sakai (#54) will fill the other seat this year as he switches over from TGM Grand Prix, with whom he made his Japanese F4 debut last year. The 18-year-old finished 24th in his main campaign but also won the Super FJ Motegi Sugo series last year.

OTG Motor Sports

OTG Motor Sports have been active in Japanese F4 since 2017 and continue to field the same line-up as they did last year. The operation is run by the Osaka Toyopet Group, which also runs Super GT and SF Lights team LM corsa. 

What started as a relationship set for one season is now entering its third, as Kenta Kumagai (#60) remains with OTG Motor Sports, the team for which he received a scholarship to compete in 2024. Having unexpectedly stayed on for a second season last year, the 20-year-old came ninth in the standings with one podium finish, though he has finally moved up the ranks too as he contests a dual campaign with LM corsa in SF Lights. 

As was the case last year, Miki Onaga (#80) will partner Kumagai in the other OTG car while continuing to race in the all-female Kyojo Cup F4 series. The 28-year-old came 26th in the standings last year, but she was more successful in the Kyojo Cup, in which she finished second overall, racing for KCMG. She also won the Kyojo Cup in 2022, when the series used closed-wheel cars, and was runner-up in the championship five times before. Alongside single-seaters, Onaga also competes in touring cars, including in the 24 Hours of Dubai earlier this year, when she finished second in class. 

TGM Grand Prix

Super Formula team TGM Grand Prix first entered the championship at the final round of 2024 with Shota Sakai, who scored a point. Last year, the team added Leon Ochiai to their line-up. He ended up being their only driver to secure points, helping them to seventh in the teams’ standings. 

TGM have reduced their line-up to just one car again this year, driven by their Kyojo Cup driver Miku Ikejima (#53). The 29-year-old will make her Japanese F4 debut. She finished 12th in the Kyojo Cup last year and previously took part in two rounds of FR Japan in 2020. 

Akiland Racing

Akiland Racing have been active in Japanese F4 since the final round in 2019. In 2023, the team came fourth in the overall teams’ championship and second in the Independent Class teams’ championship of 2024. The team will field five drivers, three in the Champion Class and two in the Independent Class. 

Toranosuke Takagi (#7), not to be confused with his namesake who raced in F1 and won a Formula Nippon title, will make his F4 debut this year. The 16-year-old steps up from karting having won the Suzuka Championship Series in 2024. He has been working together with Buzz Racing since 2015 and will race for the team’s Buzz Racing entry.

Takagi will be partnered by South Korean driver Harim Song (#8), who likewise makes his Japanese F4 debut. The 17-year-old brings previous experience racing single-seaters, as he competed in and won the KIC Touring Car Race KF 1600 class in 2022 and took part in the 2024 edition of Feed Racing as well as the 2025 Indian F4 Formula Global Shootout Program. Alongside F4, he will also compete in the F110 Cup with the team. 

You De Lu (#19), also known as Quinten Lu, made his single-seater debut in the F110 Cup Racing for Akiland this year. The 16-year-old steps up from karting, having won five Rotax Max titles across Japan and Asia since 2022. The Chinese driver will compete under an Italian license this year and, alongside the two Independent Class drivers, will race under the Akiland Racing name.

Akiland’s two drivers in the Independent class are Masayoshi Oyama (#71) and Makio Saito (#96), who both enter their eighth and ninth seasons respectively. Oyama, 60, is yet to take notable successes in the championship, having come 13th in the standings last year. On the other hand, Saito, 52, came second in the Independent Class in 2020 and 2022 and finished eighth in the class last year. 

Helm Motorsports

Helm Motorsports have competed in Japanese F4 since 2020, when co-founder Reiji Hiraki first raced for the team. That year, he bagged the team’s best results in the championship with second in the drivers’ and teams’ championship thanks to two wins. Helm have also previously competed in SF Lights and FR Japan and currently race in Super GT’s GT300 class.

The team’s only driver in the Independent Class will be William Sakai (#61), who enters his third season in the championship. The 41-year-old came ninth in class last year with a best result of third. 

Kosei Oguma (#62) will partner Sakai as the team’s only driver in the Champion Class. The 16-year-old currently leads the F110 Cup standings with a 100 per cent win rate after the first round, which marked his debut in single-seaters. Oguma – who lives in Lugano, Switzerland – previously raced for AKM Motorsport’s karting team, during which time he was coached by current F1 championship leader Andrea Kimi Antonelli. 

Team 5Zigen

Founded in 1989, Team 5Zigen first entered Japanese F4 in 2024. The team won the 2022 Super Taikyu ST-Z class and currently compete in GT World Challenge Asia alongside their F4 programme. 

Sena Yamamoto (#3) continues with the team, entering his second season in the championship after finishing 22nd in 2025.

Yamamoto was a Porsche Japan junior driver in 2022. 

“Hirobon” (#5) will partner Yamamoto, competing in the Independent Class. The 45-year-old won the class title in 2021 racing for Rn-sports but left the championship after 2022. He made two more appearances in the opening two rounds of 2024. Last year he competed in GT World Challenge Asia, coming third in the series’ Silver-Am class. 

Dr.Dry Racing Team

Dr.Dry Racing Team will add a third car and two new drivers to their line-up this year. The team first joined the championship in 2023, when they grabbed their only podium to date. The team also compete in FR Japan and the Kyojo Cup with reigning Kyojo Cup champion Rio Shimono.

Kodai Yoshida (#85) will enter his first season in Japanese F4 this year. The 17-year-old has prior single-seater experience, having raced in Super FJ since 2024. Last year, he won the Super FJ Suzuka Okayama series. 

Hachiro Osaka (#86) remains with the team as the only driver in the Independent Class this year. The 65-year-old, who enters his 11th season in the championship, came 18th in class last year. He also competed in FR Japan in two rounds across 2020 and 2021. 

Rikuto Toyoshima (#87) will make his full-time debut in the championship this year, having entered one round last year at Sugo, where he scored two points in the third race. The 18-year-old raced in the F110 Cup with the team last year, finishing fourth in the standings. 

Zap Speed

Shimizu won the 1995 Formula Mirage championship and competed in Super GT’s GT300 class from 2002 to 2005. Outside of racing – well, more or less – he is a dentist who serves many racing drivers and riders. 

Kota Umemoto (#24) will enter his first season in the championship. The 22-year-old raced in Formula Beat with First Garage last year, finishing fifth in the championship.

Soichiro Shioda (#99) will represent the team in the Champion Class as he enters his first season in single-seaters. The 16-year-old is currently taking part in the Honda Racing School’s advanced course, which would reward him with a seat in French F4 with the backing of the manufacturer should he win it. In 2025, Shioda won the Rotax Max Challenge APG’s Senior Max class.

Ragno Motor Sport

Ragno Motor Sport had a difficult first season in Japanese F4 last year. The team of former F1 driver Yuji Ide only contested three rounds, and their driver, Lin Chenghua, couldn’t qualify for the races in the opening two rounds because of car issues. He was able to race in the second and third races of the first round thanks to the format. The team ultimately switched focus mid-year to their FR Japan season instead.

After a bumpy first season in the championship, single-seater debutant Keigo Okazawa (#2) will be the team’s only driver this year. The 17-year-old steps up from karting, having competed in the All-Japan Karting Championship’s EV division with Nakajima Racing, owned by ex-F1 driver Satoru Nakajima.

The team will add a second car to their line-up later in the year.

Day Dream Racing

Yuichi Sasaki (#4) has raced in selected Japanese F4 rounds almost every year since 2015 but has only completed two full seasons since, racing for his own team Day Dream Racing or under his own name. The 62-year-old came 14th in the Independent Class last year. 

N-Speed
