Yūgai Toshi

Yūgai Toshi (有害都市, "Poison City") is a Japanese manga series written and illustrated by Tetsuya Tsutsui. It was serialized in Shueisha's seinen manga magazine Jump X from April to October 2014, until the magazine ceased its publication, and later moved to the Tonari no Young Jump website, where it ran from February to October 2015. Its chapters were collected in two tankōbon volumes.

Created in response to what amounted to a ban of Tsutsui's previous work Manhole by the government of Nagasaki Prefecture, Yūgai Toshi addresses censorship in Japan and follows fictional events similar to the circumstances of Manhole's ban.
