[1] Hasumi started his academic career as a Gustave Flaubert scholar, but also played a central role in the early introduction of the contemporary French philosophy, such as Gilles Deleuze and Michele Foucault, into Japan in the 1970s.
His introductory works of contemporary French philosophy[7] include: *Criticism, or the Celebration of Temporal Death (Hihyō Aruiwa Kashi no Saiten) (1974) and Foucault, Deleuze and Derrida (1978).
What made Hasumi widely popular in Japan is his vast amount of literary and film criticism outside of academia.
[10] Hasumi's film lectures in his early days in Tokyo attracted young Japanese filmmakers, such as Kiyoshi Kurosawa, Masayuki Suo, and Shinji Aoyama.
[11][12][13] Hasumi is also known as a novelist and published two fictional work: *A Collapsed Land (Kanbotsu Chitai)(1986) and *A Countess (Hakushaku Fujin).(2016).
