Since the launching of the hydrogen energy and fuel cell demonstration project （JHFC） in 2002，Japan has continuously intensified research and demonstrative application of hydrogen energy and fuel cells. Japan released the basic strategy of hydrogen energy in 2017，hydrogen energy is regarded as the “trump card” to ensure energy security and cope with climate change. Japan proposes to commercialize hydrogen fuel power generation by 2030，and fuel cell vehicles will be fully popularized by 2050，the national strategy of “hydrogen energy society” and its specific action plan for the overall stop of conventional fuel vehicles. In March 2019，Japan’s hydrogen energy and fuel cell Strategy Committee further updated the hydrogen energy and fuel cell strategy road map launched in 2014 and revised in 2016. Japan regards hydrogen energy as an important starting point for energy structure transformation，energy security and climate change. Its practices and experience have certain enlightenment for the development of hydrogen energy and fuel cell vehicles in China.
