She joined the Czech Philharmonic Orchestra during its tour of Japan. As a soloist of the Tokyo Metropolitan Symphony Orchestra and the Japan Philharmonic Orchestra, she appeared on the concert platforms of Europe´s music centres and at festivals in Warsaw, Zagreb, Budapest, and Helsinki. In the late 1970s she started studio work for various broadcasting and record companies. There she engaged in numerous joint projects with the Czech Philharmonic and the Brno State Philharmonic Orchestras, the Dvořák Chamber Orchestra, the Prague Chamber Orchestra, Capella Istropolitana, and the Württemberg Philharmonic Orchestra. Her recordings are available on discs released, in the Czech Republic, by Supraphon, Lotos and GZ-Digital Media; and in Japan, by Exton Octavia Records.
A significant share in her repertoire has been assigned to Czech music. Beyond that, her concert programmes have been characterized by marked focus on virtuoso violin literature.

Miss Ishikawa currently performs on violins built in the workshops of Geronimo Amati II (c. 1690) and Pietro Ambrosi (1727).
