Hasebe Yu is a member of the J-Pop group dream, and one of its original three. She made her debut as a gravure idol in 2004. Hasebe Yu was born on January 17, 1986 in Gifu Prefecture.
Yu has always been the visual focal point of dream, having been given the center position of the original group's V-formation. The more elaborate choreography of the expanded dream eliminated any standard positioning of the girls when performing, but Yu continues to be featured at the center of most group photographs. In late 2004, Yu began an ongoing series of gravure magazine shoots, with photobooks and DVD releases following shortly thereafter.
Possibly as an extension of the above, Yu is also the actress of the group, with roles in a growing number of movies and doramas. Her credits include a starring role in the late-night TV Tokyo drama Koi Suru!? Kyaba Jou and the female lead in Karera no Umi VII ～Wish on the Polestar～. Yu is also the only member to appear in dream's drama-styled PV for the song Kono Natsu ga Owaru Mae ni.
In addition, Yu co-hosted Purin-su from April 18 through December 12, 2005 and OUT★PUT throughout its 52 episode run. From October 2005 to October 2007, she co-hosted the Wednesday edition of Gocha Maze! on MBS Radio.
In mid-2007 Hasebe was placed in the unit Kingyo with Nagasawa Nao and Kayo Aiko. Fellow idol Hoshii Nanase will act as the unit's producer.
