Six artbooks have been released containing Touhou Project material. Each of these artbooks has a different theme; for example, Bohemian Archive in Japanese Red focuses on characters, while The Grimoire of Marisa is solely dedicated to different kinds of spell cards. It should be noted that Seasonal Dream Vision is semi-official; it is more of a compilation of comics from various authors, along with an original story written by ZUN himself.

Four official major comic series have been released. The first, Touhou Sangetsusei, details the mishaps and adventures of the Three Fairies of Light as they meet various characters in Gensokyo. Touhou Bougetsushou focuses on an expansion of the events that occur in Imperishable Night, and describe a voyage to the Moon to resolve a mysterious conflict. Technically, Cage in Lunatic Runagate is a collection of illustrated short stories that give more insight into the storyline. Wild and Horned Hermit focuses on a new character named Kasen Ibaraki who regularly visits the Hakurei Shrine, while Forbidden Scrollery focuses on Kosuzu Motoori who works at a bookstore in the Human Village.
As of 2017, Visionary Fairies in Shrine and Wild and Horned Hermit are still ongoing. The other comic series have been completed.

Curiosities of Lotus Asia was the first official supplement to the Touhou storyline. Now completed and compiled into a tankobon, each story is a standalone account of the everyday life of Rinnosuke Morichika, the owner of a small variety store specializing in items from the outside world.
