I don't recall seeing this here, or anywhere else, but just saw it in the August issue (#446) of Classic Images. (A Film magazine.)
Emi Ito, half of the Japanese singing duo The Peanuts (with her twin sister Yumi). They are probably best known as the Twin Fairies in the original Mothra films.
April 1, 1945 - June 15, 2012.
I really liked them in the films. (But the story says that Yumi is still with us.)
