# Keiko (singer, born 1985)

Keiko Kubota (窪田啓子, Kubota Keiko, born December 5, 1985), who goes by the mononymous stage name Keiko (stylized all caps) is a Japanese pop singer. She was one of the vocalists of the FictionJunction project started by Yuki Kajiura, and is a core member of the vocal group Kalafina.

## Biography

Keiko is from Shibuya, Tokyo, Japan. Prior to FictionJunction and Kalafina, she was in a rock vocal duo called Itokubo. She joined the FictionJunction project in 2005, and has performed on many of Kajiura's soundtracks and theme songs for anime shows. "Kaze no Machi e" (風の街へ, "To the City of Wind") was used as an insert song in episodes 19 and 21 of the anime show Tsubasa: Reservoir Chronicle, and "Nohara" (野原, "Field") was the B-side for the FictionJunction single "Toki no Mukou, Maboroshi no Sora".
In 2007, she and FictionJunction member Wakana joined Kajiura's vocal project Kalafina, releasing the song "Oblivious". During her ten years there, Kalafina released five studio albums and two compilation albums, all of which have charted in the Oricon top 10. Space Craft describes her singing as a "captivating bass voice". Following the resignation of Kajiura from Space Craft, Keiko soon left the group in April 2018. She also rejoined FictionJunction for Kajiura's concert performance of tracks from the Princess Principal anime television series.
In April 2020, she announced she was working on a solo album with Avex Trax. Her first solo single, which has the songs "Inochi no Hana" and "Be Yourself", was released in May. "Inochi no Hana" was her first song where she wrote lyrics. In September, she held a live performance titled KEIKO First Live K001 – I'm home. Her studio album Lantana was released on December 2. Her solo concert KEIKO Live K002 ** Lantana * Saita yo to promote the album is scheduled for December 16 at Zepp Tokyo and includes a livestreaming of the event. Lantana reached No. 32 on the Oricon Albums Chart.
On January 15, 2025, Kalafina has reunited with a concert in Tokyo Garden Theater for their anniversary. Yuki Kajiura was not involved in this reunion concert. On January 27, details for FictionJunction/Yuki Kajiura LIVE vol.#21 were published and Keiko was not listed among the vocalists of the event.
