I stumbled upon this pile of station maps in my crawl of tokyometro.jp. I had my file manager sort them by size, which to my delight sorted them from least- to most-complex. Here they are all on one page.
The maps were re-sorted on 2015-07-26. I first put this up in 2013, but noticed in 2015 that Shibuya Station needed to be in position #1 (at the very bottom) instead of #23.
Shibuya Station notably features an underground river that inhibited some further construction.
Note: a few maps are duplicated because they connected underground, e.g. Hibiya/Yūrakuchō.
