Biography: Riyu Kosaka
Riyu Kosaka is a J-pop singer, as well as a member of the Konami-produced J-Pop group BeForU. Kosaka was born in Yokohama, Kanagawa, Japan on January 17, 1985.
On November 20, 2000, Konami and Toshiba-EMI staff held auditions to form a J-pop group, which would eventually become BeForU. Many talented people auditioned, and Kosaka, who was then fifteen years old, was one of four who went on to join the group. The group, produced by Naoki Maeda, originally made songs specifically for Bemani games - their first song, Dive, was promoted intensely in the time leading up to the release of Dance Dance Revolution 5thMix.
After Dive's success in 5thMix, BeForU produced more tracks for inclusion in DDRMAX Dance Dance Revolution 6thMix, including Dive: More Deep and Deeper Style and Firefly. This is where Kosaka got her first solo track, True... Two different versions were included in the game, True... (radio edit) and True... Trance Sunrise Mix. For the first time for any member of BeForU, a CD single was released, including a long version of both the radio edit and the trance sunrise mix, as well as a remix of a solo performance of Dive, renamed Dive to the Night. True... was a success in the DDR community, and Kosaka continued to release other songs for use in Bemani both with BeForU and as a solo singer.
While they continued to make music for Konami, BeForU began to put more emphasis on themselves as legitimate musicians, and this included Kosaka. In 2004, the band's first CD was released, containing some solo work by Kosaka; in the same year, her first full solo album, Begin, was released. Begin contained three original songs, as well as eleven re-recorded Bemani songs, some of which were covers of other artists. A year later, she released Riyu Kosaka First Live at O-EAST 2005, a CD+DVD set of her first full-blown concert. Since that time, Kosaka has released a number of singles both on her own and with BeForU, as well as a new album with BeForU.
In 2005 and 2006, she also collaborated with Ryo Horikawa as a radio personality for Pakedio Channel, Archived October 23, 2005 at the Wayback Machine. Her song Little Wings is available on the album Pakedio Channel Vol.1.
In 2007, Riyu Kosaka recorded a song for the film Kamen Rider The Next, Platinum Smile. The song is an insert song for the movie with Kosaka providing the singing voice for Erika Mori, who portrays Chiharu Kazami, the younger sister of Shiro Kazami/Kamen Rider V3.
