Miho Hamaguchi (1915–1988) was a pioneer in the modernization of Japanese residential architecture. Despite being the first woman in Japan to be licensed as an architect, developing a theory of the emancipated dwelling, writing, consulting, teaching, and designing over a thousand projects, her life and work have been little explored by canonical historiography. Hamaguchi’s goal was to use architectural practice – in all its forms – to achieve an egalitarian society devoid of patriarchal distinctions of gender, class, or ethnicity.
