Sex Ed 120% (Japanese: 性教育120％, Hepburn: Seikyōiku 120%) is a Japanese manga series written by Kikiki Tataki and illustrated by Hotomura. It began serialization in Kadokawa's @vitamin web platform in January 2020. ASCII Media Works has collected the series in three tankōbon volumes. The series is licensed by Yen Press in English. The series follows Naoko Tsuji, a teacher who believes the way Japan teaches sex education is so poor that she decides to teach the subject in her own enthusiastic way.
The series has been praised by critics for its comedy and how its subject matter is dealt with, while criticism has been levelled at Yen Press for giving the series a "Mature" adult rating.
