Who has provided Pikachu’s Japanese voice throughout the Pokémon anime?

Ikue Ōtani has provided Pikachu’s Japanese voice throughout the Pokémon anime.

Ōtani voices Pikachu in the original Japanese television series and in Pokémon films, including Pokémon: The First Movie. Pikachu’s vocalizations remain recognizable across the character’s battles, emotional scenes, and comic moments, even when the character speaks only its name and related sounds.

The role is distinct from Ash’s Japanese voice. Rica Matsumoto voices Ash, whose Japanese name is Satoshi. Other major cast members include Mayumi Iizuka as Misty, Yūji Ueda as Brock, and Megumi Hayashibara as Jessie.

International dubs use different voice performers, so the answer depends on the language version specified. The question asks about the Japanese anime, where Ōtani is the canonical performer. She also voices other Pokémon characters in the franchise, but Pikachu is her signature role.
