Post-Apocalyptic Tokyo

Years ago, I came across images of a ruined Tokyo by TokyoGenso and was really impressed.  In anime and Godzilla movies, Tokyo is always being destroyed. Heck, it was even wiped out in a zombie apocalypse in the Resident Evil movies and in High School of the Dead.  Have you ever wondered what it would look like after the apocalypse?  I don't think I would want to visit ruined Tokyo as who knows what is lurking in the shadows, but imagery from TokyoGenso (a.k.a. Tokyo Fantasy) depict what this back to nature future could be like.
