Yuka Kashino, known professionally as Kashiyuka, is a Japanese singer, dancer, and occasional voice actor, born on December 23, 1988, in Hiroshima, Japan. She is best known as a member of the electropop group Perfume, which she joined in its early formation. Her career background is primarily rooted in music, but she has extended her activities to include voice acting and narration for animated projects.

Kashiyuka's voice acting credits include a role in the anime short series Fastening Days. In September 2017, she provided the voice for a cake shop clerk in the third installment of this YKK promotional series, titled Fastening Days 3. She also took on a narration role for the Sumikko Gurashi franchise. Kashiyuka, alongside her Perfume bandmates, served as a narrator for the television anime series Sumikko Gurashi Sorairo no Mainichi, which aired in 2023.

In addition to her direct voice acting work, Kashiyuka has a significant body of work contributing theme songs to various anime series and films with Perfume. These performances are often closely tied to the projects, such as providing the theme song for To Your Eternity Season 3. Other anime-related theme song performances by the group include contributions to the live-action Chihayafuru films, Beyblade X, and a Doraemon film. Her work is frequently undertaken alongside her Perfume colleagues, Ayaka Nishiwaki and Ayano Omoto, with whom she shares many of these credits. Her achievements in this area are as a collaborative contributor to the soundtracks of these productions, rather than as a solo artist.
