Yorushika

Biography

Yorushika (ヨルシカ) is a Japanese rock duo founded in 2017. The group is composed of N-buna, a Vocaloid producer, and Suis, a female vocalist. They are known for their juxtaposition of "passionate" and "upbeat" production and instrumentation fused with heavier lyrical content, which often explores ideas such as love and human emotion and draws from works of literature including Masuji Ibuse and Jules Verne.
The duo is extremely secretive, never publicly revealing their faces. N-buna stated that he does not want the creator to take precedence over the work.

Name

The name "Yorushika" is taken from a lyric in their song "The Clouds and the Ghost", "yoru shika mō nemurezu ni" (夜しかもう眠れずに; meaning "now without being able to sleep except at night"). The eye-designed logo mark is a motif of two moons facing each other and also serves as a clock hand, portraying the time "from 6:00 to night".

History

Prior to the formation of Yorushika, N-buna already had a sizeable following on Niconico, a Japanese video hosting website, first releasing vocaloid music on the platform in 2012. His 2013 song "Tōmei Elegy" (透明エレジー) reached first on the platform's daily vocaloid ranking. Additionally, he has produced two albums through U&R records, a subsidiary of Niconico's owner Dwango.
According to an interview with Natalie, N-buna and Suis met through a common acquaintance; Suis was a longtime fan of N-buna's vocaloid work. Suis first appeared as a guest vocalist during N-buna's two solo concerts in Tokyo. N-buna reached out to Suis to form Yorushika as part of N-buna's effort to find a "more human" voice to use in his music, as opposed to vocaloid. Since then, the two have released three extended plays and three full albums, all of which charted on both the Oricon Albums Chart and the Billboard Japan Hot 100 Albums Chart. Yorushika's popularity grew explosively, with critics noting that the lyrics seemed to strike a chord with younger audiences. Additionally, the song "Just a Sunny Day for You" (ただ君に晴れ, Tada Kimi ni Hare) became popular on the video app TikTok.
