Yutori Tanaka is credited as the original creator behind the anime series Yutori-chan. This credit establishes the creator as the originator of the series concept and characters.

Yutori-chan began as a web anime distributed by the Japanese online services company Biglobe. A limited preview of the first four episodes was available from December 29 to December 31, 2009, with the full series debut following on March 16, 2010. The series was notable for its distribution method, as viewers received an email from the title character containing a link to watch each episode. The production consisted of 25 short episodes, each approximately three to four minutes in length.

The creative team for the anime adaptation brought together director Keiichiro Kawaguchi, known for his work on Moetan and Hayate the Combat Butler, and original character designer POP, with animation production by Studio Actus. The voice cast included Aoi Yūki in the role of the protagonist, Yutori Tanaka.

The story centers on Yutori Tanaka, a high school girl who takes a part-time job in the marketing team of a medium-sized toy company called Popuu. The comedy focuses on her interactions with her coworkers, particularly the meticulous college student Shiori Tsumekomi and the strict full-time employee Reiko Dankain. The title character's name carries meaning, as yutori translates to taking it easy, a quality reflected in her relaxed and carefree personality. The series draws humor from the contrast between her approach to work and the more traditional attitudes of her colleagues, touching on themes related to generational differences in the Japanese workplace.

In the context of the series, Yutori Tanaka exists as a fictional character, while the creator credit of the same name represents the original source material from which the anime was adapted. The series stands as the primary original work associated with this creator.
