Yūko Nagashima

Yūko Nagashima is a Japanese voice actress currently represented by the talent agency Amuleto, after spending her earlier career with Aoni Production. She is also credited among the extensive Japanese voice cast associated with Toei Animation's One Piece anime.

Nagashima's signature roles date to the early 1990s, when she played Rina Takamiya opposite Kōsuke Okano in Saint Tail and voiced Yayoi Aida in Slam Dunk. Those parts remain the most prominently cited credits from her career.

Beyond her best-known roles, Nagashima voiced Sakai in You're Under Arrest, working alongside fellow performer Sakiko Tamagawa. The part came during the same early stretch of her career as her other signature 1990s roles.

Nagashima, born in 1970, debuted in the industry around 1992. She has worked continuously since then, spending her early years with Aoni Production before moving to her current agency, Amuleto.

The specific character Nagashima portrays in One Piece is not documented in publicly available records, a common situation for actors who take on brief or single-episode parts in long-running series. She is nonetheless credited among the voice cast associated with Toei Animation's adaptation.
