The 4D imaging radar market in Japan is driven by government support for road-safety technologies, the growing use of high-resolution radar in automotive and industrial applications, the increasing adoption of advanced driver assistance systems (ADAS), and the growing demand for autonomous and connected vehicles.

Market Overview

The 4D imaging radar industry is a sector that manufactures and sells next-generation radar equipment capable of providing 4D images of the Earth, including Speed/Velocity of the target, distance, altitude, and lateral angle. This equipment allows for greater resolution than conventional devices for target recognition, height determination, and motion analysis. Japan is taking an active role in the development of advanced mobility systems, which in turn are driving the demand for 4D imaging radar. The government established the Level-4 System Mobility Acceleration Committee, intending to make fully automated driving services available by 2025, and it has approved the use of Level-4 autonomous vehicles on public roads, along with projects aimed at the validation of these vehicles, such as RoAD to L4. METI’s autonomous mobility development grants (including support for regional automated services, among others) are financing trial deployments and open data initiatives, thus allowing the companies to create Level-4 systems. These regulatory and financial actions are directed towards the proliferation of cutting-edge sensing technologies like 4D radar for safety and automated driving innovation. In addition to commercial growth opportunities being created by the increasing number of robotaxis, smart infrastructure, logistics automation, and defense monitoring applications, collaboration between original equipment manufacturers (OEMs) and suppliers, chipset upgrades, and expanded testing of autonomous driving platforms are adding to the increasing demand for Japanese 4D imaging radars.
