Find everything from idols to electronics in Akihabara
If you like noise, then head over to Akihabara. It really is the home for all things electrical. I often visit here, but never for longer than needed. If you like video games then there are multiple arcades, if you like crane claw machines, then there are multiple game centres, and if you like manga and anime, there are multiple shops selling those things too. However, as much as I love Akihabara, it can be a little overwhelming for me, and I often leave with a dizzying AKB48 headache. Regardless, it really is a convenient shopping area that has all of the same things in one place. Worth a visit. Bring earplugs.
