This paper investigates how young Japanese women in contemporary Soka Gakkai (SG) navigate Japan’s continuous gender stratified society that remains culturally rooted in the ‘salaryman-housewife’ ideology. How are young SG members reproducing or contesting these hegemonic gender norms that few seek to emulate? While SG has long proclaimed that it stands for gender equality, its employment structure and organization in Japan until recently reflected the typical male breadwinner ideology that came to underpin the post-war Japanese nation-state and systemic gender division of labor. As shown here, this did not mean that SG women were without power; in fact, in many ways they drove organizational developments in the Japanese context. The recent imposition of the global framework for Sustainable Development Goals of 2015 has enabled SG to more substantially challenge its own patriarchal public front. Based on long-term fieldwork, in-depth interviews and multiple group discussions with SG members in their 20s, this article explores how SG-Japan is being challenged to follow its own discourse of ‘globalism’ and ‘Buddhist humanism’, promoted by Daisaku Ikeda since the 1990s. Using Bourdieu’s analysis of symbolic power, the research shows how Japan’s powerful doxa of ‘genderism’ that held sway over earlier generations is currently being challenged by a glocalized Buddhist discourse that identifies Nichiren Buddhism as ‘humanism’ rather than Japanese ‘genderism’.
