Sorayama is known for his fine art, illustration, and industrial design. Of the distinction between the first two, Soryama commented in an interview: "Unlike art, illustration is not a matter of emotion or hatreds, but an experience that comes naturally through logical thinking." Sorayama's first art book Sexy Robot, was published by Genko-sha in 1983. For the work, he used ideas from pin-up art, which in the book then appear as chrome-plated gynoids in suggestive poses. His next book, Pin-up (Graphic-sha, 1984), continued in the same vein. A number of his other works similarly revolve around figures in suggestive poses, including highly realistic depictions in latex and leather. His pin-up work appeared monthly for years in the pages of Penthouse magazine, and Playboy TV later aired made a television special on Soryama's art. Sorayama said of his pin-up work: "That’s my mania. I’ve been drawing them since high school. Back then, there was this thing for the Playboy and Penthouse playmates. Now, it’s the girl-next-door, idol type, but in our day, these pin-ups were like goddesses. I guess I could describe it as my own goddess cult." In 1985 Sorayama published the video Illustration Video, his first work apart from the books of illustrations. This features work he did for the films Brain Dead (1992), Timecop (1994), and Space Trucker (1995); design of trading cards, limited-edition prints, CD-ROMs, and the cover art for Aerosmith's 2001 album Just Push Play; art exhibitions; and the initial design for what would eventually become Sony's dog-like robotic "pet", the AIBO. He published an additional four books in the 1980s, and three new volumes plus a retrospective collection in the 1990s. Production models of Sony AIBO went to market on May 11, 1999. In the 2000s, Sorayama's first-generation AIBO design (the robotics of which were developed by Sony's Toshitada Doi) received the Grand Prize of Best Design award, the highest design award conferred by Japan. AIBO has since been included in the permanent collections of the Museum of Modern Art (MOMA) and the Smithsonian Institution. MOMA published a book, Objects of Design by Paola Antonelli, which included AIBO along with other noteworthy designs where form and function combine in harmony. AIBO was the first "artificially intelligent" mass-market consumer robot for entertainment applications. It has been the subject of special studies at Carnegie Mellon University and other academic institutions. Also in this decade, Sorayama produced nine more books and the Nike "White Dunk Project" included Sorayama's art among the 25 most inspiring Japanese artists.
