DOUBLE

 is an R&B solo project, and formerly a duo of two sisters. The members had been singing along with their third sister since childhood, and began a professional career after passing an audition for For Life Music Entertainment in 1995. They made their major debut on February 4, 1998 with For me.

SACHIKO passed away from a hemorrhage on May 21, 1999, and after a year long hiatus, TAKAKO returned to music while keeping the name DOUBLE to honor her sister.

Since 2006, TAKAKO has also been active as a DJ under the name DJ Lilly a.k.a. DOUBLE.
