We clarified the following three points about the success factors in crowdfunding by analyzing the data of the Japanese reward-based crowdfunding platform “CAMPFIRE” and comparing it with the research of U.S. “Kickstarter.” Firstly, it was confirmed that the increase of target amount and duration were negatively associated with the success rate, and the increase of publicity was positively associated. Secondly, it cannot be said that videos were positively associated with the success rate in Japan, which is in contrast to the existing empirical research about U.S. Thirdly, projects by founders in greater Tokyo area have a high success rate in Japan. These results will contribute to the understandings of the development process of crowdfunding in Japan.

Recently, the government promotes work style reforms. In the movement, “diversity” gathers attention as a key word. As personnel such as women, senior citizens, and foreigners get utilized, diversity studies would become more important. Although the government sheds light on the positive side of diversification, there is also the negative side. In diversity studies, researches on faultlines show us such an aspect. Therefore, we introduce Lau and Murnighan (1998), which is said to be the pioneer of the field, and explain the concept of faultline and its activation, which tends to be overlooked.
