Since the promulgation of former Abe administrations key policies, “Womenomics”, “A society in which all omen can shine”, the “Act on Promotion of Women's Participation and Advancement in the Workplace”, discussions and actions of gender equality and work-life balance started in earnest in companies, politics, and media. This thesis aims to clarify the social and cultural backgrounds and issues of how gender equalities in the workplace have been produced by referring to the previous research and the government reports. In the empirical part, I would like to examine why and how Japanese companies engage and promote childcare leave for male employees and their struggles and issues through interviews.
