Coco Tomita was born in Japan in 2002 and began to play the violin when she was four years old. She became a pupil of Natasha Boyarsky when she was six, and in 2012 she was awarded a place at the Yehudi Menuhin School where she has continued to study with Mrs Boyarsky.
In 2010, at the age of eight, Coco became the youngest contestant to win Third Prize in the Junior section of the Andrea Postacchini International Violin Competition in Fermo, Italy. Two years later, she made her debut appearance at the Cadogan Hall, London performing as a soloist with the Southbank Sinfonia.
