I was a few times in Akihabara in the late 90s and absolutely loved it. Those narrow alleys packed with electronics shops selling every niche product you could think of, backed by some huge electronic stores. Also, game arcades were still a big thing and the whole manga and anime insanity had not take off. Around 2012 I visited it again with my family and was a bit disappointed. It was much less techy and many cool electronics shops had turned into mange/anime shops. Well, I guess times will never stop changing.
