Hajime Sorayama (b.1947) is a Japanese illustrator, known for his precisely detailed, erotic airbrush portrayals of women and feminine robots. Sorayama’s work ‘Sexy Robot,’ published by Genko-sha in 1983, made his organic robotic forms famous around the world.
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’ (1984), continues in the same line. A number of his other works similarly revolve around figures in suggestive poses, including highly realistic depictions in latex and leather. His pinups appeared frequently in the pages of ‘Penthouse’ magazine.
