Japanese video dubbing,
register and rhythm under control.
VoiceStudio dubs your videos into Japanese: translation, voices, subtitles, QA, publish-ready files. Japanese demands precise register (keigo) and rhythm choices; they are set with you before production.

What matters in Japanese
Syllable-timed pacing constrains sync
Japanese is syllable-timed: sentence duration does not compress gracefully. Sync is tuned per segment, and lip-sync needs dedicated adaptation.
Keigo is a product decision
Polite (desu/masu), honorific, or plain: the speech level changes how your brand reads in Japan. It is set in the glossary before production, not improvised voice by voice.
Subtitles with their own rules
Japanese subtitles follow specific line-length conventions (roughly 13–16 characters per line) and mix three writing systems. Our segmentation respects them.
Japanese has roughly 123 million speakers according to Ethnologue, concentrated in the world's fourth-largest economy, a premium market for training and expert content.

Frequently asked questions
For corporate training and commercial content, the polite desu/masu style is the standard. Full honorific keigo is reserved for very formal communications; plain style for creator formats. We set this choice together in the glossary.
