Pokémon: Sub or Dub?
Pokémon's English version renames its cast and changed hands once. The checked credits for both tracks, and what we could not confirm about watching it subtitled.
For most English-speaking viewers, Pokémon is the dub. It is the version that ANN dates to a US broadcast from September 1998, and this page could not confirm an official English-subtitled stream of the Japanese television series. What you can usefully know is how far the English version sits from the Japanese one, and the checked credits show that the difference starts with the characters' names.
Who plays whom in the original series?
ANN's encyclopedia entry for the first series, 276 episodes broadcast in Japan from April 1997 to November 2002, credits Rica Matsumoto as Satoshi, Mayumi Iizuka as Kasumi, Yūji Ueda as Takeshi, Megumi Hayashibara as Musashi, Shinichirō Miki as Kojirō and Inuko Inuyama as Nyarth. Its English cast lists Veronica Taylor as Ash Ketchum, Rachael Lillis as Misty and Jessie, Eric Stuart as Brock and, from episode 9, James, and Addie Blaustein as Meowth, after Nathan Price in episodes 2 to 31. Ikue Ōtani is credited as Pikachu in both languages. The series entry lists OLM as the animation studio and 4Kids Entertainment as the licensor and producer of the English version,. Its listing dates the US broadcast from September 8, 1998.
Read the two cast lists side by side and the first difference is not a performance. Satoshi is Ash Ketchum in English, Kasumi is Misty and Takeshi is Brock, and Musashi, Kojirō and Nyarth become Jessie, James and Meowth. Pikachu, voiced by the same actor in both, is the one lead who sounds the same.
When the English cast changed
The English dub changed hands partway through the Advanced Generation series. ANN's entry for that series credits 4Kids Entertainment with the license for episodes 1 to 145 and also lists Pokémon USA, Inc. as a licensor. From episode 146 it credits the dubbing to DuArt and TAJ Studios, and lists Sarah Natochenny as Ash Ketchum for episodes 146 to 192, after Veronica Taylor. Bill Rogers is credited as Brock in that later dub.
If you started with the early English episodes and come back to a later series, the voices you remember have changed. That is a change inside the English version, not a difference between dub and sub.
The current series
Pokémon Horizons: The Series began in Japan on April 14, 2023, with new leads. ANN's Horizons entry credits Minori Suzuki as Liko, Yuka Terasaki as Roy and Taku Yashiro as Friede in Japanese, and Alejandra Reynoso, Anjali Kunapaneni and Crispin Freeman in the same roles in English. It lists Iyuno Media Group as the English dubbing studio, with Netflix and the BBC in the United Kingdom among the streaming outlets.
ANN's review of the final batch of Horizons Season 3 episodes, published October 11, 2026, gives its overall grade, an A, for the dub and no separate grade for the Japanese track. The review is a reminder that most English-language coverage of the series is coverage of the dub.
A fair way to compare
If you can reach the Japanese track, pick an early Team Rocket scene and hear it both ways. That is where the renamed trio, their routine and their jokes all meet, so it shows you what the English version kept and what it rebuilt. We have not compared individual lines here, and nothing on this page claims a specific joke was changed.
The practical answer is the dub, because that is the version you can easily watch. Use the Pokémon watch order to place the series and films, our checked Pokémon quotes for the lines themselves, and Pokémon Adventures if you want a separate manga story with the same creatures.
