汽车产业是日本国民经济的支柱产业。日本政府历来重视新能源汽车的技术研发与战略政策研究，全面发展混合动力、插电式混合动力和纯电动汽车以及燃料电池汽车，并将电动汽车产业政策提升为国家经济发展战略。电动汽车产业发展国家战略是日本建设低碳社会的需求，是应对全球气候变暖、履行减排义务的现实考虑，也是缓解日本能源短缺压力的重要手段，但更重要的意图是要占领未来汽车技术发展制高点，以确保日本在全球电动汽车市场的核心竞争力和霸主地位。

Japan’s administrtions have always attached great importance to the R&D of new-energy-vehicle technologies and the research on strategic policies，fully developing HV，PHV，BEV and FCV，which enables the EV（Electric Vehicle） industry policy to become part of the national strategy of economic development. The national strategy of EV development satisfies Japan’s needs of achieving a low-carbon society，and is also a practical approach of addressing climate change，fulfilling its emission reduction commitment，and relieving its pressure of energy shortage. But more importantly，Japan is aimed at becoming the champion of the technology of vehicles in the future，which can ensure that Japan will enjoy core competitiveness and hegemony in the global EV market.
