893239 or Yakuza-Nijūsan-Ku (ヤクザ23区)[a] is the project name for a collection of short films based on Yakuza (Japanese Mafia) and 23 ku (区, special wards) in Tokyo, Japan.

The project covers almost all the 23 wards in Tokyo with an extra episode shot in the City of Torrance (which has the biggest Japanese population in the continental US) in Los Angeles County.

This project was promoted through its official website with trailers and through YouTube where each entire movie is shown.

During the first promotion phase (November 27-February 14), the movies were in Japanese only, but English-subtitled versions were added in early February 2007.

January 28, 2007 Yahoo!Japan announced in its MOVIE section that 893239 collections had over 100,000 accesses on YouTube.
