In 1997, she made her debut at Lucerne Festival and Musikverein in Vienna with Rudolf Baumgartner. Zubin Mehta has been her strong supporter. When Shoji auditioned for him in 2000, he immediately changed his schedule in order to make her first recording with the Israel Philharmonic possible in the following month, then invited her to perform with Bavarian State Opera and Los Angeles Philharmonic.
