FAKKU is an English-language hentai website. The site attracts over 1 billion pageviews a month and over 9 million unique visitors.

At its core, Fakku is an aggregator that provides users with adult manga and doujinshi from Japan. Originally the content was uploaded exclusively by the sites administrators but later these privileges were shared with the community, allowing for translators to have their work seen by a much larger audience.

Fakku and its creator Jacob Grady have a known relationship with Danny Choo, Japanese TV personality and host of Culture Japan. At Anime Expo 2010, 2011, and 2012 (in Los Angeles, CA) Jacob and Danny hosted community meetups that attracted large audiences of fans and users.

Fakku was created in December 2006 by Jacob Grady while he was studying Computer Science in Massachusetts. Fakku was developed under the codename “AAH” or “All About Hentai” (which later became the site’s subtitle). Jacob originally used money from student loans to pay for server and bandwidth costs, but that quickly became unsustainable and shortly after its launch Fakku was forced to shut down. It was brought back up after user donations rescued the site in July 2007.

As of July 2011 Fakku entered into a streaming licensing deal with Kitty Media, a subsidiary of Media Blasters. The deal allows Fakku to stream select anime titles at its discretion, starting with Immoral Sisters. Both the subtitled and dubbed editions of Immoral Sisters were made available to users of Fakku at no charge.
