The Japanese Super Formula Championship runs one of the fastest closed-wheel single-seater cars outside Formula 1, and the Dallara SF23 is its current specification. Spark Model's 1:43 release documents Kazuya Oshima's full-season 2024 campaign with Team Rookie Racing, recording the No. 14 livery in resin at collector scale. It is the only 1:43 scale model of this precise car-number and season combination.
The Dallara SF23 TRD 01F: Japan's Front-Line Single-Seater
Introduced for the 2022 season, the SF23 replaced the SF19 as Dallara's chassis for the Japanese Super Formula Championship. The TRD 01F designation identifies the Toyota Racing Development turbocharged 2.0-litre four-cylinder engine, producing approximately 550 hp, which powers the Toyota-affiliated entries. At 4,890 mm in overall length, the SF23 is a full-sized open-wheel racing car built to a technical specification that demands lap times comparable to much larger-displacement machinery.
Kazuya Oshima and the Team Rookie Racing Programme
Kazuya Oshima is a Toyota-supported driver with a career spanning both Super Formula and Super GT's GT500 class. In 2024 he carried the No. 14 for Team Rookie Racing, a Toyota-affiliated development entry that functions as a talent pipeline within the Japanese motorsport ladder. The team's TRD-powered SF23 ran Toyota's factory-aligned livery scheme throughout the championship, making this particular car a documented example of Japan's structured driver development structure in top-level domestic single-seater competition.
Spark Model produces its Super Formula releases in resin, the material of choice for 1:43 racing replicas that demand sharp livery reproduction and fine aerodynamic detail. The SFJ-series releases target a specialist collector market for Japanese domestic single-seaters — a niche that receives far less coverage from mainstream diecast producers. Each release in the series typically documents a specific car number, driver and season, giving collectors a precise historical record rather than a generic livery study.
In the Display Cabinet
The No. 14 Oshima SF23 sits naturally alongside other Spark Super Formula releases from the 2024 season — entries such as those covering Tomoki Nojiri and Naoki Yamamoto — allowing a complete grid representation at 1:43. It also pairs coherently with earlier Dallara SF19 TRD models from the 2019–2021 seasons, tracing the evolution of Toyota's Super Formula effort. Collectors focused on Oshima's broader career will find it a companion to his Super GT Lexus LC500 replicas within a Toyota Gazoo Racing-themed shelf.
