Just happened to be in the Akihabara area one night and also just happened to have the Kiss Digital N handy - only took a handfull of shots because most of the shops where closed and neon lights faded down.
If you do get a chance to go to Akihabara, dont leave it too late because by 8-ish, most of the smaller shops close including Kaiyodo. The big places like Asobit and Gamers are open at that time although I dont know what time they close.
