Kogami was created by the Production I.G. staff. Writer Gen Urobuchi created the character to contrast Akane Tsunemori, Kogami's police supervisor, whose personality and ideology are opposed to Kogami's. He was designed by mangaka Akira Amano, who wanted to give the character a strong sense of individualism in contrast to the scenario of the series. Kogami is voiced in Japanese by Tomokazu Seki and in English by Robert McCollum.
