Translate Video to Japanese
A Japanese dub with the right register — 敬語 or casual — plus captions that render kanji, kana and line-breaks correctly.
Japanese video translation with AI dubbing
Japanese is a high-value, high-difficulty localization target: the audience is large and monetizes well, but machine translation regularly fails on register (formal 敬語 vs. casual speech) and Japanese captions break ugly when line-wrapped mid-word. ViralMint addresses both: the translation step takes a register instruction ('casual YouTuber Japanese', 'polite instructional tone'), and the caption renderer handles CJK line-breaking without splitting words mid-character. Whisper's Japanese transcription is among its strongest languages, so translating FROM Japanese works equally well. TTS voices include natural male and female Japanese options at both free and premium tiers.
How to translate a video to Japanese
-
Import the video
Open Translate & Dub in the desktop app and drop in your file. Local Whisper transcribes the original — on your machine, nothing uploads.
-
Translate the script
The AI translates the transcript into Japanese (日本語). Pin the register or dialect once with a plain-language instruction and the whole script stays consistent.
-
Pick the Japanese voice
Free Edge voices, premium Gemini voices, or your own cloned voice speaking Japanese — the dub renders timed to your original cut points.
-
Captions and export
Word-by-word Japanese captions burn in the same pass. Export the finished mp4 — no watermark — and post it as a native Japanese upload.
Frequently Asked Questions
Can I control formality (keigo vs casual)?
Yes — pass an instruction with the translation: 'casual YouTuber register' produces です/ます-free conversational Japanese, 'polite instructional' keeps です/ます form. Register is the single biggest quality lever for Japanese dubs, so it's worth specifying.
Do Japanese captions render correctly?
Yes — the burner uses CJK-aware fonts and line-breaking, so kanji/kana don't split awkwardly. Word-by-word caption timing adapts to Japanese's different word segmentation from Whisper's output.
Does translation from Japanese to English work too?
Yes, the pipeline is bidirectional: Whisper transcribes Japanese natively (it's one of Whisper's strongest languages), and the same translate-and-dub flow produces an English version of a Japanese original.
