Azumi Uehara (上原あずみ Uehara Azumi), real name Akane Koshikawa (越川茜 Koshikawa Akane) is a former Japanese pop/rock singer, songwriter and poet signed under GIZA Studio label.
After graduating high school, Uehara moved to Osaka to live on her own. She debuted shortly after as a pop/rock singer in 2001 when she released the single Aoi Aoi Kono Hoshi ni. It reached #9 on the Oricon and was used as the 13th ending theme for the anime Detective Conan, making Uehara yet another GIZA artist to have a song used in the series. A year later she released Mushoku, her fifth single, and it hit #5 on the charts. She also wrote the lyrics for the single. An album of the same name was released two months later. However, Uehara began limiting appearances only to live performances and magazine columns.
After this hiatus, Uehara also began to write songs for other artists, including Iwata Sayuri. In December 2005, more than three years after her last release, Uehara began releasing music again, this time with a harder rock feel. In October 2006 her second album was released, along with her first book of poems. She hasn't released anything since then.
Uehara began keeping an online blog in February 2007.
In July 2010, Uehara Azumi was expelled from GIZA Studio for fraud.
In 2012 she made an appearance in an adult film under the stage name of Yui Nagahara (長原結衣 Nagahara Yui). Later in 2013, she signed on to the AV label Muteki under the stage name Azumi.
