A small number of Japanese critics and theorists have produced the bulk of the foundational manga-studies writing in Japanese. This page collects short profiles of the most-cited figures: Eiji Otsuka, Fusanosuke Natsume, Hiroki Azuma, and Atsushi Sasaki, alongside notes on their principal contributions.
Eiji Otsuka (b. 1958)
Otsuka is a critic, editor, and theorist. He worked in the late-1980s manga industry as an editor at Tokuma Shoten and Kadokawa and has been one of the most prolific theorists of Japanese popular media since. His best-known concept is 'narrative consumption' (物語消費), the argument that postwar Japanese consumers engage with media franchises by accumulating fragments toward a perceived 'grand narrative' rather than consuming completed works. The argument is set out in his 1989 book Monogatari shōhi-ron.
Fusanosuke Natsume (b. 1950)
Natsume is a manga critic and the grandson of the novelist Natsume Sōseki. His critical writing — including the 1995 book Manga no yomikata ('How to Read Manga'), edited together with Takashi Inoue and others — established a formalist vocabulary for analysing manga at the panel, page, and sequence level that became the standard reference inside Japanese manga studies. The book is not yet available in English translation.
Hiroki Azuma (b. 1971)
Azuma is a philosopher and critic whose 2001 book Dōbutsu-ka suru posuto-modan (published in English in 2009 as Otaku: Japan's Database Animals) is the most-cited theoretical text on otaku culture in English. Azuma argues that otaku-era media consumption operates on a 'database' model in which characters and tropes are extracted and recombined separately from any underlying narrative, marking a shift from the modern grand-narrative consumption that Otsuka had described.
Atsushi Sasaki (b. 1968)
Sasaki is a critic and Tokyo-area editor whose writing on Japanese popular music, film, and anime has appeared widely in Japanese cultural quarterlies. His Nippon no Shisō (2009) is a survey of postwar Japanese intellectual history with substantial attention to manga and anime as theoretical objects.
