binaria is a Japanese music group formed in May 2006 as a three-member collaborative project featuring Annabel, Yoshihisa Nagao (永尾ヨシヒサ), and Nagi Yanagi (やなぎなぎ). The group brings together three artists under one act and has maintained a long-running presence in contemporary Japanese music since its formation.
Known by the official name binaria, the project is defined by its three-member lineup and collaborative structure. Its official website is binaria.net, and it remains a distinct entry for listeners looking up the group by name, member names, or Japanese origin.
