In 1937, Hara competed in the
III International Chopin Piano Competition in Warsaw. Hara performed in a
kimono and enchanted the crowds. When the jury did not award her a prize, the audience nearly revolted. The Polish music critic
Jerzy Waldorff wrote: Her receipt of the Audience Award marks the only time in the history of the competition that such an award was given. She returned to Japan on September 3, 1938, and gave a triumphant performance tour around the country. Around this time, the Japanese composer
Tomojirō Ikenouchi, her fellow student abroad, proposed to her in marriage, but she declined. Hara performed duets with him across Europe and continued recitals as a soloist. She also accepted a professorship at
Kobe College from April 1957 to March 1961 after refusing offers from universities in Tokyo, including the
Tokyo University of the Arts. She established the Gaspar Cassadó International Violoncello Competition, which was held ten times in Florence until 1990 and produced cellists including
Mischa Maisky, Noboru Kamimura, and Kaeko Mukoyama. In 1997, she donated her piano,
harpsichord, and Cassadó’s
music scores and materials, including his arrangement of
Franz Schubert's
Arpeggione Sonata, to
Tamagawa University in Tokyo. Hara passed away on December 9, 2001, in Tokyo, of natural causes, aged 86. ) In 2004, a manuscript score of
Bach’s
Wedding Cantata (BWV 216) was discovered in her estate. The manuscript had been purchased by Cassadó from
Felix Mendelssohn's family and was confirmed to be authentic by Tadashi Isoyama, a professor at the
Kunitachi College of Music. In 2012, Tamagawa University launched a project to catalogue the donated materials of Gaspar Cassadó and Chieko Hara, and hosted a special exhibition in 2016. ==Personal life==
