The issue of "gender integration" within the military organization has long been a major research topic in military sociology. In the last two decades, however, specific topics such as "gender mainstreaming," "diversity management," and "diversity and inclusion" have pervaded sociological studies on military organizations. In this article, I examine the current state of gender integration in the Japan Self-Defense Forces (JSDF), focusing on efforts to promote gender mainstreaming. In particular, following the National Action Plan to implement the United Nations Security Council Resolution 1325 was formulated in 2015, the Ministry of Defense issued the JSDF Female Personnel Empowerment Initiative in 2017, in which previous challenges for career development of female SDF personnel were to be removed by making virtually all job categories available for women including combat pilot, missile boat crew, and tank driver. While the number and ratio of female personnel have increased and their prospects of career development have substantially improved in the last few years, work-life conflict and sexual/power harassment remain to be challenging issues for the retention of female personnel. Due to the deep-rooted male-dominant organizational culture of the military organization, further organizational challenges remain for JSDF to shift its overarching human resource management paradigm from "Diversity 1.0" to "Diversity 2.0," with the strong commitment of top leaders to innovate organizational culture.
