Sayuri is a Japanese musician, singer and songwriter.
In 6th grade, Sayuri was impressed by the fact that, despite being idols, Kanjani Eight formed a band. They inspired her to take up guitar as a hobby. Sayuri began composing music during her second year of junior high school, aspiring to the lyrics and songwriting of Kanjani Eight.
Afterwards, under the name Asuka, she joined an acoustic duo called LONGTAL based in Fukuoka, she started performing in the streets and live houses of places like Hiroshima, Osaka, and Nagoya. By this time, she had dropped out of high school.
In 2012, as part of LONGTAL, Sayuri was awarded the Grand Prix at the finals of the fifth Music Revolution, a competition sponsored by Yamaha Music. Afterwards, she became active as an indie artist. She adopted the name Sanketsu Shōjo Sayuri (酸欠少女さユり, lit. "Hypoxia Girl Sayuri") which is symbolic of her calling herself a 2.5-dimensional parallel singer-songwriter.
Sayuri moved to Tokyo in 2013. She held her first solo live in March 2015 at Tsutaya O-East in Tokyo. Later that year, Sayuri made her major debut at 18, performing the ending theme song for Rampo Kitan: Game of Laplace.
On December 7, 2016, she collaborated with Yojiro Noda of RADWIMPS to release her 4th single "Furaregai Girl." Concerning the single, Noda said, "I had already composed the song and created the lyrics, but I knew that I couldn't sing it. For a while, I searched for the true owner of the song. Then, by chance, I was in the recording studio next to Sayuri. I listened to her CD, and in that moment, something that was only a vague silhouette of a song became crystal clear. It was a song that she was meant to sing."
On March 1, 2017, Sayuri released her fifth single "Parallel Line," which was featured as the ending song to the anime adaptation of Scum's Wish. She released her first album Mikazuki no Koukai on May 17, 2017. It reached first on Oricon's Daily Album Ranking and 3rd on its Weekly Album Ranking.
