TokyoGenso is a series of amazing illustrations based on real locations in Tokyo but in ruined condition. It looks like the places has been abandoned for many years and become some sort of a dead city after an apocalyptic event. The artist of this series actually paint the illustration on an actual photo, thus the creation of this highly detailed, surrealistic illustrations.
TokyoGenso provides a very good imagination on how Tokyo will look like when abandoned. Well I think in real life this will not actually happen but it will not stop the illustrator’s imagination. Below are some of his works, and to see more please check out his deviantART gallery, Pixiv gallery (in Japanese and requires log in) or his Ameba blog.
