Yen Press is the manga and graphic novel imprint of Hachette Book Group. Its Japanese name is エン プレス (En Puresu). It is located on 237 Park Avenue, New York. In addition to their regular book releases, Yen Press produces Yen Plus, a monthly manga anthology. The company's varied list demonstrates an interest in publishing a wide variety of Japanese manga, Korean manhwa, and other international content. In addition to translated material, Yen Press has released original series, most notably a manga adaptation of James Patterson's Maximum Ride and Svetlana Chmakova's Nightschool.
Yen Press was founded in 2006 by former Borders Group buyer Kurt Hassler and DC Comics VP Rich Johnson (who left the imprint in the fall of 2008). In July 2007, it was announced that Yen Press was to absorb ICEkunion, a Korean publisher that had been releasing manhwa to the United States. While the manga titles bearing ICEkunion's label would be continued to be sold in stores, subsequent printings would bear the Yen Press logo. Kurt Hassler assured fans, "We plan to pick up all the existing [ICEkunion] titles...We’re going to continue everything, so fans shouldn’t worry. None of these series are going to fall into a void."
Yen Press had previously stated that it would like to release 30 – 40 volumes within 2008. One of the flagship titles of their original English artists line has been announced to be Nightschool, which would be released by Canadian Svetlana Chmakova, who is known for her Tokyopop title Dramacon. During New York Comic Con 2008, Yen Press announced that the titles Soul Eater, Nabari no Ou, Sumomomo Momomo, Bamboo Blade, and Higurashi no Naku Koro ni would run in their monthly anthology magazine Yen Plus. The first issue debuted on July 29, 2008. In 2009, Yen Press announced that it had acquired the rights to Yotsuba&! and Azumanga Daioh from their former license, A.D. Vision. In September 2009, Yen Press rereleased the first five volumes of Yotsuba&!, in addition to releasing the sixth volume; Azumanga Daioh was rereleased with a newly translated version in December 2009. Yen Press is the only current publisher of Yotsuba&!.
Other titles published by Yen Press include the graphic novel adaption of the American book series The Twilight Saga, Black Butler and The Melancholy of Haruhi Suzumiya.
