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, Okinawan music, Celtic music, chindon (a kind of Japanese street music), swing jazz, as well as Japanese, Chinese and Korean folk musics. 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).
