The objective of this paper is to investigate the leadership of young researchers. In recent years, career formation support for young researchers is being developed. In this research, to support young researchers' various career options, interview was conducted to 15 active leaders across different fields and ages. We asked questions about 1) attitudes and behaviors necessary for leaders, 2) abilities that helped to take on the current leading position, and 3) ability required for young researchers. The responses from the interview can be summarized as "the necessary attitude and behavior", "the useful skill", and "the required condition." Among all these responses, common ideas such as "the mission and vision", "the humility", and "the foundation of inter-personal relationship" can be pointed out in this research.
