I’ve been there about 5 years ago; I remember being the only bit of Akiba which sort-of matched the image of the area that I had in my mind before the trip. The rest was anime-anime-anime-porn-porn-porn-porn and a bunch of generic electronics retailers with ware that you could easily find on the internet 30% cheaper. (well, and a delicious arcade museum of sort, marked by a huge Mario mural – but it was well hidden and quite empty of patrons).
Sad to see it go, but then again, Japan today is very different from the '80s, the electronics market has moved to China and Korea.
