When people ask “when did Chainsaw Man come out,” they usually mean either the manga or the anime, so here are both.

Manga release

  • The Chainsaw Man manga by Tatsuki Fujimoto began serialization in Weekly Shōnen Jump on December 3, 2018.
  • That first run (the Public Safety Arc) continued in the magazine until December 14, 2020.
  • A second part later started on Shueisha’s Shōnen Jump+ digital platform in July 2022.

Anime release

  • The Chainsaw Man TV anime adaptation first aired in Japan in October 2022.
  • Its widely cited premiere date on streaming (including the U.S.) is October 11, 2022.

So, in short: Chainsaw Man “came out” as a manga in December 2018 and as an anime in October 2022.
