Kujira

Wakako Matsumoto (松本 和香子), better known as Kujira (くじら), is a Japanese seiyū from the Tokyo Metropolis area. She is employed by 81 Produce. Veteran seiyū Shigeru Chiba, another member of 81 Produce, gave Kujira her nickname (meaning "whale").

Kujira's voice is described as hoarse and androgynous. Thus, many of her characters are middle-aged. In Slayers, she only did the voice of the Shopkeeper's Wife. Despite having such a minor role in Slayers, she is well-known as the voices of Otose in Gintama and Orochimaru in Naruto.
