Itsumo Togashi, whose name is written in kanji as 富樫一望, is an original creator and animation professional known primarily for the picture book Aoi Hane Mitsuketa! Sagashitemiyō Mijika na Tori-tachi. This work, a children's picture book, serves as the foundational material for an anime adaptation of the same name, establishing Togashi's role as an original creator in the context of multimedia projects.

The picture book was published in November 2020, and its story follows two siblings from the city who discover a blue feather and embark on a journey with a guiding crow to find its owner, encountering various birds along the way. This source material was adapted into a six-episode original net animation series that aired from April to June 2021, produced by the studio Noovo. In the context of this anime, Togashi is officially credited as the original creator of the picture book upon which the series is based.

Beyond this work as a creator, Togashi's professional credits demonstrate a career in the animation industry with contributions to several notable productions. These credits primarily include roles in key animation and finishing departments. Among the projects to which Togashi has contributed are major films and series such as A Whisker Away, the second season of Mob Psycho 100, Run with the Wind, and both the first and second seasons of Mobile Suit Gundam: The Witch from Mercury. Additionally, Togashi is credited with animation and paint work on the second episode of the original net animation Fastening Days.

The combination of Togashi's work as the originator of a published picture book and as a contributing animator on high-profile projects illustrates a dual presence within the industry, bridging original content creation for younger audiences with technical animation work on major franchise titles.
