Kamitsubo began his career in the anime industry as a production manager for Film Magic in the early 90s. He transitioned to digital photography and visual effects work for Media Vision and, later, Gonzo in the mid and late 90s. In the early 2000s, he started doing episode directing and storyboard work. In 2004, he worked under Akiyuki Shinbo on the original anime seriesMagical Girl Lyrical Nanoha, and the following year was brought into Shaft by Shinbo, where his first project with the company was as an episode director on Tsukuyomi: Moon Phase. He would later make his series directorial debut with Shinbo and Shaft in 2007 with Hidamari Sketch. Shinbo considered Kamitsubo, setting designer Tatsuya Oishi, and art directorHisaharu Iijima to be the core staff responsible for the foundations of the style and presentation of Hidamari Sketch, even after both Kamitsubo and Oishi had left the series' production in their respective seasons. Kamitsubo continued working with Shaft for a few years before deciding to base his work mostly out of Xebec, including his own series Softenni and Hen Semi. In 2012, however, he announced that he would be leaving the industry, and his final work would be as a storyboard artist and episode director on the tenth episode of To Love Ru: Darkness under the pseudonym Motona Hino. Despite this, Kamitsubo returned to the industry in 2014, acting as a storyboard artist for Xebec's series Argevollen beginning with the 13th episode. Since 2017, Kamitsubo has mainly worked on series produced by Doga Kobo.
