I actually went to the AKB shops in NMB, AKB and the SKE shop. All the theaters were closed, probably due to the big Budokan concert
I bought a lot of stuff from the NMB48 shop. I ended up getting a free pen since I spent over 3000Y (easily), most things are minimum 800Y.
The main shop in Akihabara

Sunshine Sakae; where the SKE48 theater and café are located. Wasn't able to get a picture of the shop/café front because of the crowds and security there.



This the 4th floor I believe, the lines are waiting to get in the café and the shop

Take the Nagoya Metro from Nagoya station to get to Sakae Station, you have to check the exit signs to get to Sunshine Sakae

To get to the NMB48 Café/shop and theater you need to check a map as I was easily confused. The NMB48 café web site has directions, best bet is to exit the Namba Walk from Namba Station (not the JR line)
