Wanz Factory (ワンズファクトリー, Wanzu Fakutorī) is a Japanese adult video production company located in the Toshima ward of Tokyo, Japan.

[1] Japanese adult video studios are usually divided into mainstream and independent types, the mainstream or "pro" studios such as Kuki, Alice Japan and h.m.p often being larger and older than the "indie" companies such as Soft On Demand, Cross, Dogma and Moodyz while the latter usually have less censorship and are more adventurous in their offerings.

Wanz Factory is one of the indie companies with a specialty in AV Idol videos and large-busted "big boobs" models.

[4] The major Japanese video distributor DMM, a division of the Hokuto Corporation, listed more than 2000 DVD titles for Wanz Factory in September 2011.

[9] For the 2009 AV Grand Prix contest, Wanz Factory nominated Roomshare (パイズリ狭射 トリプル痴女大乱交) [AVGP-150] co-starring busty actresses Hikari Hino, Akira Ichinose and Miruku Matsuzaka, and directed by Asao Takai.
