Born and raised in Saga, Japan, Rie Tsuji started on piano at the age of 6. By age 10, she was already composing original pieces on piano and was entered into the Japanese National Competition for Young Composers (J.O.C.). One of her original pieces became a required repertoire in the Yamaha School of Music piano book for teachers' final performance examinations.

From 1991-1998, she won several awards in the Japanese Music Competition for classical piano performance. During her senior year in high school, Rie had a chance to study at the Belarus Conservatory. While she was there, Rie was hand picked by the Piano Chair to perform at the program completion recital. After completing the Belarus Conservatory program, she enrolled in the Tokyo Conservatory and graduated with a Bachelor's of Music Degree in Classical Piano Performance.

Directly from Tokyo, Rie moved to Boston, Massachusetts to study jazz piano performance at Berklee College of Music, on scholarship and graduated with a music diploma majoring in Professional Music. Here she cut her teeth with the next generation of modern jazz musicians such as Andre Ward, Robin McEllhatten, Darren Barrett, among countless others. In January 2006, she joined R&B vocalist Eric Benet on his album tour.
