Toshiko Kohno is one of the leading orchestral flutists in the United States. She came from her native Japan to study in the United States, where her principal teachers were Joseph Mariano of the Eastman School of Music and Doriot Anthony Dwyer, the long-time principal flutist of the Boston Symphony Orchestra.
In 1973, Kohno entered the Geneva International Competition, where she won first prize. In the same year she joined the Buffalo Philharmonic Orchestra. In 1976, she became associate principal flutist of the Montréal Symphony Orchestra.
In 1978, she earned the position of principal flutist with the National Symphony Orchestra of Washington, D.C., and has remained in that position during a period of rapid and marked improvement in that ensemble under music directors Mstislav Rostropovich and Leonard Slatkin. She has appeared with the orchestra as soloist often, and has also made solo appearances with orchestras around the world, including the Tokyo Metropolitan Orchestra, the Orchestre de la Suisse Romande, the New Japan Philharmonic, and the San Francisco Symphony Orchestra.
A frequent artist at the Marlboro and Aspen Music Festivals, she is also a member of the National Symphony Orchestra Wind Soloists. She is a teacher, and has appeared as soloist in recordings with the NSO, including the Millennium Symphony, The Old Moon in the New Moon's Arms, by Michael Kamen.
