Den Den Town is Osaka's answer to Tokyo's mammoth Akihabara district, a 1km-long shopping street of over 300 stores specializing in cut-price electronic appliances.
Dissected by a four lane road, the two sides of the street form a chaotic vertical jumble of multicolored shop signs, flashing neon and flapping banners, soundtracked by a hundred different advertising jingles, in-store broadcasts and the constant hum of traffic. The sheer array of choice is overwhelming at first - everything from DVDs, computer hardware, plasma screen TVs and games to security equipment, used goods, manga comics, machine tools and, this being Japan, open fronted shops selling pornographic videos.
Prices, while not always amazingly low, were very competitive, though it definitely pays both to haggle and to shop around in Den Den Town, as prices seemed to vary significantly from one shop to the next. A number of the shops, notably the several branches of Ninomiya, also offer tax-free deals to foreigners on production of your passport.
To get to Den Den Town, take the Sukaisuji underground line to Ebisucho station. Exits 1A and 1B both lead directly to the street itself. Namba and Nipponbashi stations are also within walking distance.
