Mitsubishi Heavy Industries (MHI) has unveiled its vision for Japan’s next-generation trainer jet.
At the recent 2025 DSEI defense expo in Chiba, the company introduced its T-X trainer concept, designed to prepare pilots for an era of air combat dominated by fifth- and sixth-generation fighters.
Built to replace the aging Kawasaki T-4, the twin-engine, two-seat trainer features a modern digital cockpit with touchscreen controls and smart displays, giving pilots a training environment that mirrors modern fighter jets.
The T-X also incorporates built-in simulation tech, enabling pilots to practice radar evasion and missile engagements mid-flight without live weapons or real threats.
MHI hasn’t revealed when a prototype might fly, but officials said the concept will be formally pitched to Japan’s Ministry of Defense soon.
Emerging Contenders
MHI is not the only potential contender in Japan’s search for a new jet trainer.
Reports from 2024 indicate that Tokyo is considering the T-7A Red Hawk, developed jointly by Boeing and Saab, as a possible replacement for the Kawasaki T-4.
Already in service with the US Air Force, the Red Hawk could offer Japan benefits in interoperability and cost efficiency by aligning with an established platform.
There has also been speculation about Korea Aerospace Industries’ supersonic T-50 Golden Eagle, though no official moves have been confirmed.
Japan’s Aircraft Programs
The T-X trainer announcement comes as Japan ramps up efforts to modernize its air fleet and lead in next-gen aviation tech.
Earlier this month, Tokyo received three F-35 Lightning IIs at Komatsu Air Base, part of a $23-billion deal with the US for 63 F-35A and 42 F-35B jets.
Japan is also teaming up with the UK and Italy to develop a sixth-generation stealth fighter under the Global Combat Air Programme.
Set to arrive by 2035, these jets will replace the Eurofighter Typhoon and Mitsubishi F-2, packing advanced stealth and sensor tech.
Key players in the program include MHI, BAE Systems, Leonardo, and their global supply chains handling final assembly and subcontracting.
