Why Japanese

Why translate English videos into Japanese?

English-language creators, schools and companies translate their videos because four in five people on earth don't speak English, and most of them would rather watch in their own language.

About 126 million people speak Japanese, almost all of them in Japan, one of the world's largest economies and biggest markets for games, anime and online video. Japanese viewers overwhelmingly watch in Japanese, so a Japanese version opens a market English alone rarely reaches.

Language notes

What changes from English to Japanese

Politeness in the grammar

Japanese changes verbs and vocabulary with the level of politeness (keigo). Videos for customers, students and clients normally use the polite desu/masu style; watch the first dub to confirm the tone fits your audience.

Three scripts, short lines

Japanese subtitles mix kanji, hiragana and katakana and need far fewer characters than English for the same sentence, so they stay short and easy to read.

One of the fastest languages

Japanese is spoken at about 7.8 syllables a second, one of the fastest rates measured (Pellegrino et al., 2011). AutoDub lets each line take the time it needs rather than squeezing it.

Coming from English

English is compact: the same idea usually takes more words in Spanish, French or German, and localization teams plan for 15–35% longer text. AutoDub lets the timing stretch slightly instead of speeding the voice up, so the translated speech keeps a natural pace.
