Her renowned teachers included Akiko Teranishi in piano and Motoko Nabeshima in harpsichord.
Upon winning a prize at the 1986 International Harpsichord Competition in Bruges, she travelled to Europe to continue her studies with Scott Ross, who had been one of the judges, and finally established Paris as her base in 1990. Following on Ross's premature passing, she was sought out to carry on his work by the head producer of Erato Records, Michel Garcin, and she issued her debut CD on the label in 1991 as their first Japanese artist.
Since 1992 she has toured with the Israel Chamber Orchestra as their resident harpsichordist, and she plays extensively abroad including at festivals in France and Italy. Her collaboration with contemporary dancer Santiago Sampere, performed in Paris and Tokyo, was highly praised for its ambition, and in 2006 there was a three-hour special broadcast of her music on Radio France.
She also earns constant attention for her work within Japan, where she has devoted enormous effort to chamber music activities, in addition to appearing on radio and television, writing essays for magazines like DIME, and publishing a book entitled Suddenly Parisienne.
She also maintains a lively and active recording career, debuting with a recording of Bach's English Suites, and following with his Goldberg Variations, French Suites, Tocattas, Scarlatti's Sontates Inedites, as well as the titles Cinema Clavecin, Je L'aime, Latina, and Chaconne. Most famous is her album Sonates Inedites, for which she was authorized by her teacher Scott Ross before his death to supplement the works necessary in finishing his major project of recording Scarlatti's complete sonatas.
In October 2003, Sone started a series of J. S. Bach performances at Hamarikyu Asahi Hall in Tokyo, ultimately totaling twelve concerts in a space of six years, playing the complete English Suites and French Suites in conjunction with the Italian Overture, the French Overture, and the first book of the Well-Tempered Clavier. Albums of the series were released by Avex Classics and won the 20th Music Pen Club Award in the category of Best Recording Product. Her most recent release was a re-recording of the Goldberg Variations, which she had first put on CD 10 years prior, in 1999.
2010 saw the start of a highly-acclaimed project in the Aeolian Hall of Tokyo's Ueno Gakuen University to perform all the harpsichord works of Couperin and Rameau.
Concurrent with her performance activities, she is presently continuing her studies under the brilliant Skip Semp?.
