Slow Charging-Station Roll-Out Outside Tōkai and Kantō Corridors

While Tokyo and Aichi benefit from a well-established network of fast chargers, rural areas continue to face significant infrastructure gaps. This disparity has created challenges for the adoption of Battery Electric Vehicles (BEVs), which in turn affects the demand for e-axle shipments. Although the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has increased subsidies for fast chargers in fiscal 2025, the economic feasibility of installing private chargers remains a barrier in regions such as Hokkaido, Shikoku, and Kyushu. The lack of sufficient charging infrastructure in these areas underscores the need for further policy and industry efforts to bridge the gap.

Higher Upfront Cost Premium Versus PM E-Axles Until Economies of Scale Achieved (Pre-2027)

EESM packages with lower power outputs continue to face a cost premium compared to other e-axle technologies. The inclusion of advanced excitation hardware and the limited production scale of certain electronic components largely drives this premium. However, initiatives under the Green Innovation Fund program are expected to gradually reduce this cost disparity over the coming years. By advancing technology and scaling production, the program aims to make these packages more competitive in the market, potentially narrowing the cost gap significantly by the end of the decade.
