Main Aim

The influence of the media is very large, and the transmitted information promotes “gender stereotypes” and “unconscious bias”, and forms our ideas in a biased manner. In addition, in order to improve Japan’s sustainability, a society in which all people can play an active role is a major premise, and in forming public opinion that the realization of gender equality is more important than ever, the role of media is very important. The Media Group is developing initiatives based on the following three pillars:

1. Promote the diversity of decision-making bodies of media companies
2. Eradicate gender stereotypes in advertising and commercials
3. Hold continuous study sessions for the media



Main Aim

The 30% Club has the catchphrase “Classroom to Boardroom” and is actively collaborating with universities to develop various initiatives from the perspective of strengthening the pipeline. At 30% Club Japan, the University Group is formed in the summer of 2020, and we continue to develop various initiatives in the future. We will notify you in a press release when the direction is set.
