I think I've mentioned it before but when asked where one should go to look at cute girls in Tokyo - I always give the same answer. Its not Shibuya, Harajyuku or Jiyugaoka but in the Otaku haven Akihabara!
As you can see from these photos taken the other day, Akihabara is filled with gorgeous sweet cute looking 2D girls absolutely everywhere!
These photos explore Softmap, Animate, Kotobukiya store, Melonbooks and a look at the Sega Game Center towards the end.
If you get off at Akihabara station and make your way down Chuo Doori Street and keep your eye on the side roads then you will be able to find all these stores.
Get off at the Electric Town exit at Akihabara.
