How it works
How do you get English subtitles for a Japanese video?
To translate a Japanese video to English, drop it on this page. Its sound is taken out in your browser and transcribed as Japanese; the lines are translated and laid out as English subtitles within the time each was spoken. Then load the SRT in a player or upload it.

Save the subtitles
English SRT or VTT, ending .en.srt; switch to Original for the Japanese subtitles.
Why do the English subtitles hold more text than the Japanese?
Because Japanese says in about half the characters what English does. The English subtitles get lines of up to 42 characters, read at 17 a second, and are laid out after translation, so they needn’t match the Japanese subtitles one for one.
Do English subtitles follow the Japanese word order?
No. Japanese puts the verb at the end, so the page translates a whole line first and only then cuts the English into subtitles. Viewers read natural English order, shown during the seconds the Japanese sentence is spoken, not word for word in step with it.
How well does Japanese speech come through in English?
The meaning comes through, though in our test of whole recordings Japanese scored below most languages. Many lines were exact, like “head to the waterfront in Kowloon”. Where the transcript wrote a word that merely sounds like the one spoken, the English subtitle translates the wrong word.
Such slips show up as an English subtitle that doesn’t fit the scene. Switch to Original, find the Japanese subtitle at the same time, and correct the English line in the SRT.
What happens to place names and brands in the English subtitles?
Most come back as they’re known in English. Katakana names like シックスフラッグスセントルイス came back as “Six Flags St. Louis in Missouri”, and Skype stayed Skype. Less familiar people can be spelled by sound: ピケJr. came back as “Pike Jr.” for Piquet Jr.

Should you publish the Japanese subtitles too?
Often, yes. Switch to Original for Japanese subtitles in lines of 16 characters, with timing that matches the speech. Japanese viewers and learners of Japanese can then pick their own track, and you can check any English line against the Japanese at the same moment.

FAQ
Questions about English subtitles for Japanese videos
Is the Japanese to English video translator free?
Yes, with no account or watermark: 3 videos a day, each up to 30 minutes. English and Japanese subtitle files are both included.
Can I watch a Japanese video with these subtitles?
Yes. Most desktop players open an SRT from their subtitle menu, and many load it by themselves when it sits beside the video under the same name.
Does it read the English aloud?
No. You get English subtitles to read, not an English voice, and the video itself isn’t changed.
Will it work on a video with some English in it?
This page hears every part as Japanese. For a video that switches between Japanese and English, use the main video translator with the spoken language on Detect automatically.
Do the subtitles show who is speaking?
No. The web page writes the words and their timing only. NoteOwl on a Mac adds speaker names to the SRT files it saves.
Is the video sent anywhere?
Not the video. Your browser takes the sound out on your device; short pieces of it go to a cloud AI transcription service and the Japanese text to a cloud AI translation service, which discard them. The picture never leaves.
