Ikue Ōtani has voiced Pikachu in the Japanese Pokémon anime since its beginning.
Ōtani provides Pikachu’s distinctive Japanese voice, including the character’s repeated name call and expressive cries. Unlike many animated characters, Pikachu generally communicates through variations of its name rather than extended human dialogue, making the voice performance especially recognizable.
She began the role with the anime’s 1997 debut and has continued voicing Pikachu across television episodes, films, and many related productions. Pikachu’s voice is therefore closely tied to the character’s identity in Japan and in versions that retain the original Japanese performance.
Ōtani is sometimes confused with Rica Matsumoto, the Japanese voice actor for Ash Ketchum, or with English-language performers who voiced Pikachu in localized productions. She also voices other notable anime characters, but Pikachu remains her most internationally recognized role. The character’s voice is one reason Pikachu can remain the mascot even when the anime’s human cast changes.
