Born in Tokyo, Miyoko Sato started to study the violin at the Suzuki School, continuing with Gabriel BOUILLON at the Conservatoire National Supérieur de Musique in Paris. There she graduated with top honors, receiving a "Brilliant 1er Prix".
She continued studies of chamber music with Joseph CALVET and Jacques FEVRIER. Then Ferdinand LICHNEWSKY assisted with starting her professional career.
For her first appearance at the THEATRE du CHATELET in Paris, with the ORCHESTRA COLONNE directed by Pierre DERVAUX, she dared to choose the Concert en D major K 218 de MOZART, and SCHÖNBERG's concert op. 36, rarely played due to its extreme difficulty.
Her early international career as a soloist brought her to France, Germany, Finland, the United States, Japan, the Netherlands, and the United Kingdom where she concerted with the Royal Liverpool Philharmonia and the London New Philharmonia Orchestra.
On her request, the Japanese composer Toshiro MAYUZUMI wrote "Gsenjo no Aria" (Aria in G) for violin and orchestra, which she staged in Paris as worldwide first performance with the ORCHESTRA COLONNE, directed by Marius CONSTANT. At the same event she also interpreted MENDELSSOHN's concert for violin and orchestra.
