Editing Yotsuba&! (section)

== Development ==
In 1998, Azuma published a [[One-shot (comics)|one-shot]] manga and two [[webcomics]] called "Try! Try! Try!", in which Yotsuba's adoptive father Yousuke Koiwai, Ena, Fūka, and Asagi first appear.<ref name="Clayton1"/> Although some of these characters—including Yotsuba herself—are largely the same as in ''Yotsuba&!''; Fūka has a different character design, a more mischievous personality, and a different spelling of her given name (in "Try! Try! Try!", it is written with the [[kanji]] {{nihongo2|[[wikt:風#Kanji|風]] [[wikt:夏#Kanji|夏]]}}, meaning "wind-summer"; in ''Yotsuba&!'', it is {{nihongo2|[[wikt:風#Kanji|風]] [[wikt:香#Kanji|香]]}}, meaning "wind-scent").

Azuma started writing ''Yotsuba&!'' a year after the conclusion of his previous manga, [[Azumanga Daioh|''Azumanga Daioh'']]. No crossovers between the two works occurred until the sixteenth volume of ''Yotsuba&!'' in 2025, which features a cameo appearance from ''Azumanga Daioh'' character Ayumu "Osaka" Kasuga, who is revealed to now be working as a P.E. teacher.<ref>{{Cite web |last=Bueno |first=Daniel |date=2025-02-27 |title=New Yotsuba Manga Features Azumanga Daioh Cameo |url=https://www.siliconera.com/new-yotsuba-manga-features-azumanga-daioh-cameo/ |access-date=2025-02-28 |website=Siliconera |language=en-US}}</ref>
