Erika Amazake’s voice actor in Medabots is Eri Sendai in the Japanese version. In the English dub of the original TV series, Erika is voiced by Lisa Yamanaka.
For the Japanese version of Medabots (Medarot), the key name attached to Erika—called Arika Amazake in Japanese sources—is Eri Sendai. Behind The Voice Actors lists her as the Japanese voice for the 2001 TV series and notes that she has voiced the character most often across the franchise, including later appearances such as Medabots: Spirits and Medarot S: Unlimited Nova.
Japanese Voice Actor: Eri Sendai
Date of Birth
October 30, 1981. Public biographical sources list Eri Sendai’s birth date as October 30, 1981.
About Eri
Eri Sendai is a Japanese actress, voice actress, and narrator from Tokyo. Her official website says she began with a children’s theater troupe in 1989 and is now active as a voice actor and narrator; it also lists Arika Amazake in Medarot among her principal roles. Her site further notes that she founded the voice-acting agency Green Note on July 27, 2020.
She is also well known for roles beyond Medabots, including Triela in Gunslinger Girl, Rei Saotome in Yu-Gi-Oh! GX, Milk / Milky Rose in Yes! Precure 5 GoGo!, Toka Takanashi in Love, Chunibyo & Other Delusions, and Caesar in Girls und Panzer. Those credits show the range of her career, but for Medabots search intent, Erika/Arika Amazake is one of her defining franchise roles.

Full Current Filmography
The list below reflects documented credits visible in Eri Sendai’s official profile and major public biographical sources used for this article. Because I did not rely on a complete official master résumé that enumerates every single role across all media, this should be treated as a documented-credit filmography and may not be exhaustive.

Other documented screen / voice work
- Public biography sources also describe her as active in narration, stage work, radio, and variety appearances before and alongside her voice-acting career, though those sources do not provide a single exhaustive title-by-title master list in one place.
Critical Reception
The strongest public evidence around Eri Sendai is career reputation and role prominence, rather than a large body of English-language critical essays focused on one performance. Her official profile foregrounds Arika Amazake in Medarot as one of her representative roles, and BTVA’s franchise listings support that by identifying her as the actor who has voiced Erika/Arika most often. That combination suggests the role is one of her core long-term character associations.
More broadly, public biographical sources frame Sendai as a versatile performer with enduring recognition across children’s anime, action series, and character-driven ensemble shows. In that context, Erika/Arika matters because it is one of her earlier recognizable franchise roles and remains one of the parts most directly tied to her name in Medabots cast databases.

English Voice Actor: Lisa Yamanaka
Date of Birth
June 16, 1983. Public biographical listings identify Lisa Jai Yamanaka’s birth date as June 16, 1983, and list Toronto, Ontario, Canada as her birthplace.
About Lisa
Lisa Yamanaka, also credited as Lisa Jai and Lisa Boynton, is a Canadian actress and voice actress. Public biography and credits pages identify her as the voice of Erika Amazake in the English dub of Medabots, and also highlight her for roles such as Wanda Li in The Magic School Bus and Yoko in Timothy Goes to School.
For this search query, Yamanaka is the core English-language answer because Medabots cast listings and Erika’s character page both credit her as Erika Amazake’s English voice in the original TV dub. Those same franchise listings also note that Bryn McAuley voiced Erika in Medabots: Spirits, so Yamanaka is best understood as the main English voice for Erika in the original series rather than every English-language incarnation of the character.
Hometown
Toronto, Ontario, Canada. Public biography sources list Toronto as Lisa Yamanaka’s birthplace, and IMDb also ties her background to Toronto schooling.
Career Highlights
The role most directly tied to this article is Erika Amazake in Medabots. Behind The Voice Actors lists Yamanaka as Erika’s English performer in the original TV series, which makes this one of her most search-relevant anime dub credits.
Her other best-known documented voice roles include Wanda Li in The Magic School Bus, Yoko in Timothy Goes to School, Sherry Birkin in Resident Evil 2, and Paula Morton in Dino Crisis 2. Public biography sources also note later advocacy and stage work, including activity as a spoken-word artist and advocate for disabled actors.
Full Current Filmography
The list below reflects documented credits visible in the public sources used here, especially IMDb, Behind The Voice Actors, and the public biography page for Lisa Yamanaka. Because I did not locate a fully itemized official résumé covering every screen, game, and stage credit in one place, this should be read as a documented-credit filmography and may not be exhaustive.

Other documented work
Public biography coverage says Yamanaka later expanded into theatre, independent films, spoken-word performance, journalism, and disability advocacy, especially after developing rheumatoid arthritis.
Critical Reception
I did not find a substantial body of mainstream criticism focused specifically on Lisa Yamanaka’s performance as Erika Amazake. The available public record is much stronger on cast verification and career credits than on formal reviews. What is clear is that voice-actor databases continue to surface Erika as one of her identifiable anime dub roles, while her wider recognition online leans more heavily toward Wanda Li and Yoko.
More broadly, public biography sources frame her career as notable not only for child and teen voice roles in 1990s and early-2000s animation, but also for later advocacy work in diversity and disability representation in media. That gives her profile a second dimension beyond nostalgic dubbing credits alone.
