Sayuri (さユり) (born June 7, 1996, in Fukuoka) is a Japan singer-songwriter.

In 6th grade, she was impressed by the fact that, despite being idols, Kanjani Eight formed a band. They inspired her to take up the 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 her hometown of Fukuoka and 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 Shoujo 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.

In 2013, she moved to Tokyo and held her first solo live in March 2015 at Tsutaya O-nest in Tokyo. Later that year, Sayuri made her major debut at 18, performing the ending theme song for the anime adaptation of the manga 乱歩奇譚 Game of Laplace (Rampo Kitan: Game of Laplace) ).

On December 7th, 2016, she collaborated with Yojiro Noda (野田洋次郎) of RADWIMPS to release her 4th single “フラレガイガール (Furaregai Girl)”. Concerning the single, Yojiro Noda (野田洋次郎) said (translated into English):

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 1st, 2017, Sayuri released her fifth single “Parallel Line,” which was featured as the ending song to the anime adaptation of クズの本懐 (Scum’s Wish). She released her first album ミカヅキの航海 (Mikazuki no Koukai) on May 17, 2017. It reached first on Oricon’s Daily Album Ranking and 3rd on its Weekly Album Ranking. This was a significant jump from her previous singles and a milestone in her career. Her sixth single 月と花束 (Moon and Bouquet) on February 28, 2018; the song was used as the ending theme of the anime Fate/Extra Last Encore.
