Driving Factors

The e-axle markets in Japan are driven by substantial financial incentives and infrastructure investments, significantly boosting e-axle demand as EV penetration increases. For 2024, the Ministry of Economy, Trade, and Industry raised its Clean Energy Vehicle (CEV) subsidy budget to JPY 129.1 billion, an almost 35% increase from the previous year, offering up to JPY 850,000 for BEV purchases and JPY 550,000 for PHEVs, making electrified vehicles more affordable for consumers.

Simultaneously, the number of government-subsidized EV chargers surged by 270%, from 3,077 units in 2022 to 11,397 in 2023, significantly expanding fast charging networks and reducing range anxiety. This has allowed more consumers to consider BEVs and PHEVs with e-axles. As a result, EV market share in Japan has been steadily growing. Projections indicate that Japanese EV market revenues will rise to c. USD 7.2 billion by 2025, supporting the growth of e-axle adoption as OEMs localize production to meet demand. With continued subsidies and charging infrastructure expansion, Japan’s policy environment will drive sustained growth in e-axle production and adoption.

Restraining Factors

The e-axle market in Japan is restrained by high production costs, limited charging infrastructure, technological complexities, supply chain challenges, and slow EV adoption in certain segments, affecting large-scale deployment and manufacturer profitability.
