Yukimura's crisis with school and lack of interest with his growth and jobs worried his parents.

[2] Yukimura was first inspired to become a manga artist after reading Fist of the North Star as a boy.

Once graduating from college at 22, he met Kaiji Kawaguchi who found his potential to become a manga author.

He met Dai Morimura who taught him about drawing manga and find his own style rather than imitating others.

[6] Yukimura made his debut with the hard science fiction manga Planetes, serialized in Weekly Morning magazine from 1999 to 2004 and adapted into a 26-episode anime series by Sunrise.

[9] For this work he received the 2009 Japan Media Arts Festival Grand Prize in the manga category.

[15][16] Yukimura praised the Vinland Saga anime for solving the manga's pacing issues and adding new content.

[19] Yukimura's sensation during the Cold War and the September 11 attacks were projected on Thorfinn's character who is traumatized by his actions as a viking and thus decides to find Vinland in order to make a land where people from different races are able to live together peacefully.

[22] In response, Isayama said he admires Yukimura for his detailed art and foreshadowing, remarking that the breaks are necessary to create such a consistently high-quality work.

[21] Among other preferred works, Yukimura enjoys horror stories, most notably Junji Ito's, Nokuto Koike's, and Motosuke Takaminato.
