Hajime Katoki

By Jenxi Seow



Hajime Katoki (カトキハジメ Katoki Hajime, 1963) is a mechanical designer. He designed mecha for the Gundam series, as well as video games such as the Super Robot Wars and Virtual On series.

He was quoted in his art book Gundam Fix saying, “Do people, like myself, spend time imagining what it would be like if Gundam robots were actually present on the streets of our cities? Are you sure you’re not limiting yourself to the images that were offered in the animated series? One of the reasons that I fell in love with Gundam was that it excites me to imagine what it would be like if these machines actually existed, and I worry that other fans may be losing out.”

He said he hoped his work would catch the attention of viewers, “Then people who had never before been drawn in by the magic of these giant robots may discover their attraction for the first time.”

Katoki was also involved in the color scheme design of Toyota Team Kraft’s SC430 (#35, GT500) that raced in Super GT seasons of 2006 and 2007. His colour scheme was later replaced by Gundam Exia-like colour scheme on July 2007 for the fifth race in 2007 season to promote *Mobile Suit Gundam 00.
