Nipponbashi is a shopping district of Naniwa Ward, Osaka, Japan. The area is centered along Sakaisuji Avenue, extending from the Ebisu-chō Interchange of the Hanshin Expressway in the south, to Nansan-dōri (just east of Nankai Namba Station) in the north. Known colloquially as "Den-Den Town," Nipponbashi is known for its many shops which specialize in furniture, tools, and "otaku" interests such as electronics, animation, comic books, and collectibles. Nipponbashi is often compared to Akihabara Electric Town, its equivalent (in terms of focus) in Tokyo.

Although written with the same characters 日本橋 in Japanese, Nihonbashi in Chūō, Tokyo is a different place and has a different pronunciation.
