Kitayama graduated from the Notre Dame Academy, a girls-only high school in the
Kansai region. She then attended
Kansai University and graduated with a degree in
sociology. While she was in university, she was a member of the school's light music club. After graduating, she spent a year in
New York City. Returning to
Osaka in the late 1990s, she started her singing career by performing at various
jazz clubs. After achieving fame in the locality, she was discovered by
record producer Shinichi Osawa, better known as Mondo Grosso. In 1998, Kitayama was featured in
Zeebra's ''Mirai e no Kagi (Osawa's Realized Mix)
released in the mini-album The Rhyme Animal Remix EP.1.'' She came up with the alias
bird around this time, because her head resembled a bird's nest during her debut. Moreover, she expressed that she wanted her music to echo the song of small birds. On March 20, 1999, she released her first single
Souls on Osawa's label
RealEyes. In July of the same year, bird released her first
eponymously titled album on the
Sony Music Japan label, which sold over 700,000 copies and won her the award of Japan Gold Record for Newcomers. After RealEyes became independent from
Sony Records, bird was able to become the lyricist and producer for her own music. She is married to illustrator
Jun Miura. == Discography ==
