Secret Comics Japan gathers nine short works from a new generation of Japanese underground manga artists active in the 1980s and 1990s. Selected by a former editor of the legendary avant-garde magazine Garo, the anthology presents a cross-section of the taboo‑breaking, experimental comics that flourished outside the mainstream. The stories range from the surreally beautiful to the graphically gruesome, each offering a distinct artistic voice and narrative approach.

The collection opens with The Life of Momongo, a story by Norimiza Ameya with art by Junko Mizuno, in which a strange creature moves through a dreamlike world. Gedatsu Man by Hironori Kikuchi depicts a protagonist grappling with existential detachment. Swing Shell by Yuko Tsuno presents a brief, surreal encounter. Jr by Yoshitomo Yoshimoto explores adolescence through an offbeat lens. Heartless Bitch and Painful Love are two short pieces by Kiriko Nananan that examine emotional cruelty and intimacy. Punctures by Shintaro Kago delivers a grotesque, boundary‑pushing sequence. Mutant Hanako by Makoto Aida turns a schoolgirl into a surreal creature of violence. Editor Woman by Benkyo Tamaoki offers a satirical look at the publishing industry. The volume closes with Palepoli by Usamaru Furuya, a cryptic, visually dense journey.

No single narrative connects the pieces; instead, the anthology acts as a showcase for the diversity of underground manga of the era, emphasizing personal expression, stylistic innovation, and a willingness to confront uncomfortable subject matter.
