Yotsuba&!

is a manga series written and illustrated by Kiyohiko Azuma. It has been published in the monthly magazine Dengeki Daioh of ASCII Media Works since January of 2003. It has been collected into 15 tankōbon volumes. It depicts the daily adventures of a young girl named Yotsuba as she learns about the world around her, guided by her adoptive father, neighbors, and friends. Various characters in Yotsuba&! were previously featured in Azuma's one-shot manga "Try! Try! Try!". The term "Yotsuba to" means "Yotsuba and," which is reflected in the chapter titles, many of which are formed as "Yotsuba and [something]."

The manga was licensed for English-language distribution by ADV Manga, which released five volumes from 2005 to 2007. Volume six was originally scheduled to be released in February 2008, but was indefinitely delayed.

Anime
An anime spin-off based on cat versions of Azuma's character Danbo titled Nyanbo! was announced and began airing on September 26, 2016 as part of a “mini anime” program. This project did not adapt any of the Yotsuba&! manga. It was broadcast in Japan on NHK-E and simulcasted overseas on Crunchyroll.

Despite the manga's popularity and the success of Azumanga Daioh, no announcements have been made regarding an anime adaptation for Yotsuba&!. In an entry on his website from May 15, 2005, Azuma stated that there were currently no plans to animate the manga. He reiterated this on December 5, 2008, stating that the stories and style of Yotsuba&! are not well-suited for animation.

Reception
Yotsuba&! is illustrated in a full-page format, unlike the vertical four-panel strips in Azuma's earlier series, Azumanga Daioh. This gave him more artistic scope.  Azuma's work on Yotsuba&! is known for its clean art, detailed backgrounds, and expressive facial expressions. He is highly praised for his joyous tone, slice-of-life storytelling, comedic writing, and eccentric yet realistic characters, especially Yotsuba herself.
