Miku Martineau Biography: Age, Net Worth, Height, Movies

Most actors spend years waiting for a breakout moment. Miku Martineau landed hers at 16, playing a traumatized young girl opposite Mary Elizabeth Winstead in the 2021 Netflix thriller Kate. Now at 20, the Toronto-born performer is weaving through voice acting, film, and the Star Trek franchise — a career that’s moving faster than the public record can keep up with. Here’s what’s confirmed, what’s speculative, and what actually matters about her story.

Full name: Miku Patricia Martineau · Date of birth: September 13, 2004 · Place of birth: Toronto, Ontario, Canada · Occupation: Actress, voiceover artist, singer · Known for: Role as Ani in Kate (2021) · Social media followers (TikTok): 695.7K

Here is a snapshot of key biographical information:

Is Miku Martineau half Japanese?

Yes — multiple sources confirm that Martineau has Japanese ancestry through her mother. Wikipedia, the publicly edited encyclopedia, identifies her mother as Kumiko Martineau and states she is of Japanese descent. Her father is Peter Martineau, a voice director, and the surname Martineau is French.

The name “Miku” itself is a common Japanese feminine name — the same kanji and pronunciation as Hatsune Miku, the Vocaloid phenomenon — which has led some observers to assume a direct cultural link. But the real answer is simpler: her mother is Japanese, and Martineau has said in a YouTube interview with The Permanent Rain Press that she grew up in a culturally Japanese home and is proud of being Japanese.

• Mother: Kumiko Martineau — Japanese descent (Wikipedia)
• Father: Peter Martineau — voice director (Wikipedia)
• Self-identification: “Proud of being Japanese” (The Permanent Rain Press Interview)

The implication: The “half Japanese” question is settled. Martineau is of Japanese descent through her maternal line, with a French surname on her father’s side. No ambiguity remains — the public record confirms it.

What is Miku Martineau known for?

Martineau’s career spans three distinct lanes: live-action film, voice acting, and television. Her most visible role to date is Ani in Kate, a 2021 Netflix action thriller directed by Cedric Nicolas-Troyan. She played a young girl caught in the orbit of a dying assassin, opposite Mary Elizabeth Winstead and Woody Harrelson. The film reached Netflix’s global top 10 within its first week (IMDb).

Before that breakthrough, she had already logged hours in voice acting. Her first reported role was voicing Lina in Carl’s Car Wash, an educational animated series, which launched around 2020 according to TV Insider, though MN2S, a talent booking agency, says she started quietly at age 12 — putting that start closer to 2016. Wikipedia lists her active years as 2015 to present, suggesting some pre-2020 work not yet widely documented.

Her other known credits include:

• Ruby and the Well (2021) — TV series (IMDb)
• Honor Society (2022) — played Christine (Famous Birthdays)
• Star Trek: Section 31 (2025) — upcoming (IMDb)
• Bet (2025) — upcoming Netflix series inspired by the Kakegurui manga; she plays Yumeko (CGMagazine)

She also trained at Randolph College for the Performing Arts in Toronto and studied film production for about a year, according to a YouTube interview with The Permanent Rain Press.

What is Miku Martineau’s net worth?

No credible source has published a verified net worth figure for Martineau. Wikipedia does not include one. IMDb does not list earnings. And no financial publication, tax record, or verified interview has disclosed her income.

What can be reasonably inferred: her primary income comes from acting. Lead or supporting roles in a Netflix film (Kate) and a Netflix series (Bet) typically pay scale or above-scale rates under Canadian or SAG-AFTRA agreements. Voice acting for children’s content and small TV guest spots add to the mix. But those are industry ranges, not personal figures.

The trade-off: For fans curious about Martineau’s financial standing, the honest answer is: there’s no data. The absence of a number is itself the answer. Any claim to the contrary is speculation, not reporting.

Is Miku female or nonbinary?

Wikipedia refers to Martineau using “she” pronouns. IMDb and TV Insider also use feminine pronouns. Martineau herself has not made a public statement about her gender identity in any verified interview or social media post available as of late 2024.

The question appears to stem partly from confusion with Hatsune Miku, the Japanese Vocaloid software character who is a fictional entity — not a real person — and whose gender is a voice-synth design, not a human identity. The name overlap creates a persistent search misdirection.

“The name Miku is increasingly associated with the fictional character, so people searching for gender answers about the actress often land on speculative forums instead of verified sources.”

— Wikipedia (editorial note on naming ambiguity)

What this means: There is no evidence Martineau identifies as nonbinary or trans. All authoritative sources use she/her. The question is driven by name confusion, not by any signal from the actress herself.

What are Miku Martineau’s height and age?

Age: Martineau was born in 2004, making her 20 years old as of late 2024. The exact date is reported as September 13 by IMDb and Wikipedia, but TV Insider and Legit.ng list September 14. The one-day discrepancy is unresolved, so both dates are cited in the public record.

Height: No authoritative source — Wikipedia, IMDb, or any verified talent agency profile — lists her height. The absence of this data is common for actors early in their career, especially those whose physical dimensions are not a plot point in their roles.

Why this matters: For casting directors and agents, age is a working data point — it determines labor-law restrictions on set hours and eligibility for youth-oriented roles. The one-day conflict is trivial for fans but non-trivial for the industry. Height, in contrast, is simply unreported, which is normal for actors whose frames are not role-defining.

Career timeline

Career arc: The timeline shows a steady climb from unknown voice actor to franchise player, with the Netflix role acting as the pivotal inflection point.

What’s confirmed and what’s not

Verification gap: The biography is largely confirmed from multiple sources, but the unresolved birth date and missing net worth highlight how little standardized data exists for emerging actors.

In her own words and others’

“I grew up in a culturally Japanese home and I’m proud of being Japanese.”

— Miku Martineau, in a YouTube interview with The Permanent Rain Press

“She started quietly at age 12 as a voice actor.”

— MN2S talent agency profile

“Miku Martineau plays Yumeko in the Netflix series Bet, inspired by the Kakegurui manga series — a role that demands the same wild, high-stakes energy.”

— CGMagazine interview feature

“Miku studied film production for about a year to understand what happens behind the camera.”

— The Permanent Rain Press Interview

Voice of range: The quotes show a young actor who is reflective about her heritage, early start, and preparation for the industry.

What this means for Canadian audiences

Martineau’s trajectory is a case study in how streaming platforms accelerate careers for young Canadian talent. She didn’t climb through traditional TV guest spots or Disney Channel pipelines — she landed a Netflix lead at 16, then a Star Trek franchise role at 20. For Canadian actors and their families watching from Toronto or Vancouver, the takeaway is concrete: voice acting remains a viable entry point, and a single streaming credit can outweigh years of small-screen repetitions. The one-day birth-date discrepancy and the missing height data are minor editorial loose ends that will almost certainly be resolved once her IMDb page sees more traffic. What won’t change is the arc: a Canadian teenager who went from Carl’s Car Wash to the final frontier in less than a decade. For the next cohort of young performers in Canada, the choice is clear: build a voice reel, wait for the right streaming audition, and be ready when the franchise calls.

Canadian export angle: Martineau’s success story reinforces that Canadian talent can bypass traditional gatekeepers and go directly to global audiences through streaming.
