The official Log Horizon manga was illustrated by Hara Kazuhiro, the illustrator of the light novels. It followed the main Log Horizon storyline. The series was licensed by Yen Press for an English release.
On July 8, 2015, Hara announced that the manga would officially be put on hiatus due to a bone problem.
While there were several chapters in the manga, only one volume compiling the first seven chapters was released. The remaining chapters were published only in magazines, and up to the tenth chapter can be read on its official site.
