Reiko was born in Tokyo and began her musical training as a pianist. She read musicology at the Kunitachi College of Music where she started playing the viola da gamba, having lessons with Yukimi Kanbe and Tetsuya Nakano.
In 1991 she came to Britain to study gamba with Richard Boothby, winning the foundation scholarship at the Royal College of Music. Whilst there, she won the concerto prize and completed her post graduate study with distinction. Since leaving the RCM, she has established herself as one of the leading gamba players in the UK, appearing in venues including the Royal Festival Hall, Wigmore Hall and the Royal Opera House as a chamber musician, orchestral player and soloist. She has worked with many leading conductors and orchestras including Sir John Eliot Gardiner and the English Baroque Soloists, Sir David Willcocks and the English Chamber Orchestra, Paul McCreesh and the Gabrieli Consort, Kurt Masur and the London Philharmonic Orchestra and Richard Egarr and the Academy of Ancient Music.
Reiko has been a frequent performer at Sligo Festival of Baroque Music, never failing to astonish and excite.
