Tamaki Miura (三浦 環 Miura Tamaki?, February 22, 1884 – May 26, 1946) was a Japanese opera singer who performed as Cio-Cio-San in Puccini's Madama Butterfly.
She was born on February 22, 1884 in Japan.
Miura made her operatic debut in Tokyo in 1911 and the same year went to Europe to perform and study. She was first cast as Cio-Cio-San by the innovative director Vladimir Rosing as part of his Allied Opera Season held in May and June 1915 at the London Opera House.
In the autumn of 1915, she performed the role in America for the first time in Chicago with the Boston Opera Company. She also sang in St. Louis, Missouri, in October that year. Positive reviews led to further performances in both Madama Butterfly and Mascagni's Iris in New York City, San Francisco and Chicago, before returning to London to work with the Beecham company. In 1918 she returned to the United States where for two seasons she performed both Madama Butterfly and André Messager's Madame Chrysanthème. The latter was not well-received, being viewed as a warmed-over Butterfly. In 1920 she was a guest performer at opera houses in Monte Carlo, Barcelona, Florence and Rome. Upon her return to Japan from this tour, she stopped in Nagasaki in 1922 to see places connected with the opera and to give a concert.
