Etsuko Nishio is a Japanese former voice actress known for her association with Aoni Production and for work connected to anime voice performance rather than a solo music career. Born 西尾悦子 on March 9, 1973 in Toyota, Japan, she belongs to the generation of seiyuu who became active during the 1990s, a period when anime voice acting was gaining greater cultural visibility in Japan.
Public information about Nishio’s career remains limited, so she is often discussed in the context of 1990s seiyuu history rather than through a large documented discography or a widely publicized media profile. Even so, her name remains relevant for readers researching Aoni Production voice actors and the broader anime industry of that decade. Available catalog data also links her profile to Universal Music Group, adding another point of reference for viewers tracing her career history.
