Technology foresight is a systemic national science and technology policy in Japan, where it has been consistently and effectively implemented. To date, Japan has implemented technology foresight research 10 times, thus meaningfully promoting research and development in science and technology in Japan, the technological innovation and management abilities of Japanese companies, and a deep understanding of the development law of technology. This paper introduces the methodology, modes, implementation system, and survey process of Japan's 10th technology foresight; analyzes its experiences and problems; and provides reference and guidance for technology foresight in China.
