Soul Flower Union also known as SFU, is a Japanese musical group that incorporates Asian styles and world music styles into a rock and roll band. They are known for their blend of psychedelic, rock, and Okinawan, world music, and Chin-Don (Japanese street music). Most of their songs are written and performed in Japanese, although they are fond of using phrases from a number of other languages, including English, French, Italian, Korean, Arabic and Ainu (the language of the native people of Hokkaido, Japan).
