I've visited twice. Visiting is great, I never had any issue with locals. The only problems I had were with other tourists.
I've heard that actually living (and working) in Japan is completely different. There are nuances you have to learn about and deal with.
Akihabara is fun, no doubt. There are a fair few new and used shops to buy merch. You can probably find/buy anything you're looking for in particular there, but you're right it's a "noob trap".
I was supposed to go again last March. I hadn't been to Nakano broadway yet, so it was on my list of places to visit.
Apart from everything else in the mall, the HQ for Mandarake is located there. I'm kind of upset I didn't get to go.
In my opinion, it is a must go. I have been to many places. This is my favorite place for travelling thus far! If you like Gundam, make sure you visit Diver City in Odaiba!
lol @ tourists with the 5ft tall backpacks don’t know how to get on the train during Tokyo rush hour.
