Yuuri Aoyagi 青柳悠里 (born May 22, 2007), known mononymously as Yuuri, is a Japanese singer and songwriter. In 2026, YUURI became an artist of LUNIERE ATELIER, a private music maison. He holds the title of the Atelier's sole Muse, The Muse is not merely a figure of inspiration. YUURI represents the artistic, aesthetic, and sonic vision of the Atelier itself. His presence gives the maison its central creative expression, extending from music into the wider language of image, atmosphere, and design.

 

He is also regarded within the Atelier as an auteur — an artist devoted to the authorship of his own craft, with his music and creative identity developed through a singular artistic perspective. At the center of YUURI's work is a belief in the importance of craft. Singer, songwriter, and composer are not separate roles within his practice, but different expressions of the same artistic voice. His music begins with authorship and finds its final form through performance.

 

His position as LUNIERE ATELIER's Muse extends this philosophy beyond music. The Atelier's artistic, aesthetic, and sonic identity is expressed through YUURI, creating a continuous relationship between the artist and the world surrounding his work.
