Female Cabinet Ministers Day is observed in Japan every July 19 to commemorate the appointment of Masa Nakayama as the first woman in the Japanese Cabinet. Nakayama, who was appointed as the Minister of Health and Welfare in 1960, represented a significant milestone in the advancement of gender equality in Japanese politics. The day serves as a celebration of women's contributions to government and a reflection on the ongoing challenges regarding gender equality. Although it is not a public holiday, it highlights the progress made and the work still needed in this area. Since Nakayama's appointment, over 30 women have served as Cabinet Ministers, with the First Koizumi Cabinet (2001–2003) holding the record for the most female ministers. This observance encourages discussions about women's roles in politics and the importance of continued efforts towards equality.
