Abstract: Artificial intelligence is in a new round of development “boom”. Many countries have elevated the development of artificial intelligence to the national strategic level, and “national competition” is more fierce. The development of artificial intelligence has a profound impact on national security and economic and social development. Investigating the dynamic path and development prospect of Japans artificial intelligence strategy can provide reference and inspiration for China. This paper summarizes the dynamic changes of strategy formulation and implementation, and prospects of Japans artificial intelligence development in economic, social and military fields, as well as the challenges it faces. In recent years, Japans artificial intelligence has developed rapidly. China should learn from its useful experience, continue to improve policy systems and refine goals, promote government-industry-university collaboration, and accelerate the construction of artificial intelligence ethical governance system.
