Japanese dubbingJapanese dubbing that gets politeness right.

One scene, up to two minutes, in one target language.

A film scene at night: a woman laughs on a sofa while a man leans by the window.

それを言うためだけに、わざわざ来たの?
じゃあ、夕飯食べていって。

Original laugh
Illustrative script · no audio. The words change with the language; the actor's laugh stays.

The original film, carried into Japanese.

Japanese changes with both the listener and the speaker: keigo for a boss, plain speech for a friend, and a first-person word (watashi, boku, ore) that fits the character.

How to dub a film into Japanese

Spelo creates the dub and mix

Every line is written for its scene, voiced with the original emotion and mixed over the film's own sound.

Review and fix lines in Studio

Your team signs off the language, changes any line and re-voices it in seconds.

Export your finished MP4

Download the dubbed video once your team is happy with every line.

Japanese dubbing, shaped for your audience

Japanese builds relationships into grammar, so a word-for-word dub sounds wrong to native viewers.

  • Politeness levels

    Keigo, polite and plain speech mark rank and closeness in every sentence.

    Spelo: Spelo settles who each character is and how they speak to each other before writing a line.

  • Pronouns are character

    Whether a character says watashi, boku or ore tells the audience who they are.

    Spelo: Each character keeps one voice and one way of speaking across the film.

  • Different rhythm

    Japanese lines can run shorter or longer than the original and must still fit the shot.

    Spelo: Lines are placed at the original timing, and speed can be adjusted line by line.

  • Names in katakana

    Foreign names need one consistent katakana spelling throughout.

    Spelo: Each foreign name gets one katakana spelling in the brief, used in every line.
