Nakano Broadway was developed in the context of the Japanese economic miracle, wherein as Japan rebuilt in the aftermath of the Second World War, multiple megastructures were constructed.
Among these were Nakano Broadway and nearby Nakano Sun Plaza, which were designed to be self-contained living and entertainment complexes.
The mall opened in 1966 as a shopping and apartment complex housing shops, restaurants, apartments, and a rooftop terrace with a swimming pool and garden.
While not a metabolist building, Nakano Broadway is noted as being influenced by metabolist architecture.

By the 1980s, Nakano had been eclipsed by Shibuya and Roppongi as districts that catered to luxury commerce, and Nakano Broadway began to decline in popularity.
As shops in Nakano Broadway are owned by individual retailers and not leased by a central mall administration, young entrepreneurs were able to acquire space in the mall with relatively small amounts of capital.
Mandarake, a secondhand manga store, opened in the mall in 1980; Nakano Broadway subsequently shifted to being a destination for otaku-related goods, as stores catering to this demographic opened in the mall following Mandarake's success.

Today, Nakano Broadway remains a major destination for both domestic otaku and otaku tourists in Japan, catering to a niche clientele relative to mainstream otaku destinations in Akihabara and Ikebukuro.
The physical design of the mall remains largely unchanged from its original 1966 construction and is often cited as an example of Shōwa era architecture.
The mall was designated an at-risk building for earthquakes of a magnitude of 6.0 or greater by the Tokyo Metropolitan Government in March 2018, as the building was constructed prior to the implementation of contemporary seismic standards in 1981 and has not subsequently been retrofitted to be earthquake-resistant.
