Rin' was a Japanese pop group which combines traditional Japanese musical instruments and style with elements of modern pop and rock music. It is a female trio of Tokyo National University of Fine Arts and Music alumni who graduated in 2003. The band made their performing debut in December 2003, at Meguro Gajoen, and in April 2004, their first single, called "Sakitama," was released by avex trax.
According to the band's website, the name Rin' comes from the English word 'ring', the Japanese word Wa (和, meaning both 'ring' and 'Japanese-style'), and from the trio's hope to create a 'ring', or circle, of music.
Since their debut, the band has performed in many venues around the world, and have released four singles and several albums. A number of their songs have been used as themes for anime and movies, most notable is Fuhen used in the Samurai 7 anime. .
Their chief international album, Inland Sea, was released worldwide: in Europe and the United States on April 25, 2006 and in Japan on August 30, 2006, featuring guest performances by Leigh Nash  and Lisa Loeb.
According to the band's website, as of 13 February 2009, Rin' had put an end to their activities and decided to disband.
