Katsui’s works, like his pictured poster for Pleats Please, explore vibrant and ethereal colors much like the Psychadelica movement. At the same time, he manages to evoke a soothing feeling with smooth gradients that don’t overwhelm the viewer.

Most interesting is that Katsui’s work focuses on the idea of “Iki.” In an interview for Hesperios Magazine, Katsui explained that he became intrigued with the idea after reading a 1930 book called “Iki no Kōzō” by Shōzō Kuki. In it, Kuki argued that “iki is ultimately what underlines the Japanese aesthetics: indirect, understated.” Katsui calls it “the fleeting moment, that you could easily miss.”
