This paper focuses on changes in gender-role attitudes through studies on fathering support lectures, and thus obtains feedback which can improve future lectures. The primary attention falls on men's gender-role attitudes, and how the attitudes initiated in the 1960s underwent significant changes between the 1970s and 2000s. This paper concludes that in the high economic growth period of the 1960s, the concept of fathering support lectures did not exist. Men's attitudes began to change in the following decades and the possibility that men should fill a supporting role for women had caused concern. At this time, people also recognized the importance of the child care issue. The findings in this study indicate the potential demand for fathering support lectures. In the 1990s, fathers' influences on infant development became a topic of concern. Meanwhile, many studies began paying more attention to the phenomenon. This period can be termed the growing stage. In the coming Act on Advancement of Measures to Support Raising Next-Generation Children, the government gets involved in the lectures. As a result, future lectures about fathers' lifestyles are required. In addition, lectures about father-child activities are also important in the future.
