Japanese to Portuguese

Translate Japanese Video to Portuguese

Japan and Portugal have traded since Portuguese ships reached Nagasaki in the 1500s, and today Japanese firms, tourism campaigns, and consumer brands court Portugal and the wider Lusophone market. Take a Japanese recording and get a European Portuguese version back: pt-PT voiceover, translated captions, and Portuguese on-screen text, with lip sync, ready to review before export.

What gets translated

A real European Portuguese version, not Japanese with subtitles

Subtitling a Japanese video leaves your Portuguese audience reading captions while the Japanese audio plays underneath. ngram builds an actual European Portuguese version: the Japanese speech, kanji and kana alike, is transcribed and translated, a pt-PT AI voice re-narrates it on the original timing, the captions are rebuilt in Portuguese, and any Japanese titles or lower thirds on screen are re-set in Portuguese. The Latin-script captions are broken to stay readable rather than carrying over the dense CJK lines of the source.

It carries the register across, not just the words. Japanese leans on keigo, its layered politeness system, and that formality maps to a proper European Portuguese register: the polite o senhor and a senhora forms for a corporate or B2B audience, or the informal tu for a casual creator delivery. The output is European Portuguese throughout, pt-PT vocabulary and grammar rather than Brazilian, so viewers in Lisbon or Porto never get pt-BR phrasing. If you need Brazil instead, that is a separate direction at /video-translator/japanese-to-brazilian-portuguese.

European Portuguese voiceover

The narration is re-voiced in natural pt-PT with business-appropriate delivery, timed to the Japanese original.

European Portuguese captions

Captions are translated into Latin-script Portuguese and re-timed, with pt-PT vocabulary kept distinct from Brazilian.

On-screen text

Japanese titles, callouts, and lower thirds come out in Portuguese, not left in kanji or kana.

AI lip sync

Mouth movement adjusts to the Portuguese voiceover so a Japanese talking-head cut still reads as native.

Why European Portuguese

Why Japanese teams translate video into European Portuguese

Reaching Portugal and the Lusophone world means European Portuguese, not a Brazilian cut.

01

Reach Portugal and Lusophone Africa

European Portuguese opens Portugal plus Portuguese-speaking African markets like Angola and Mozambique in a single pass. A Japanese demo, campaign, or briefing becomes usable across those markets without a re-shoot.

02

Show local care with a true pt-PT cut

Portuguese viewers notice immediately when they are handed Brazilian vocabulary. A genuine European Portuguese version signals that a Japanese brand entering the Lusophone market did the work, instead of shipping a pt-BR file and hoping nobody minds.

03

Bring Japanese content out of Japan

Japanese product demos, creator content, and corporate training that would otherwise stay inside Japan reach a Portuguese-speaking audience. Polite keigo transcribes accurately on the way in, so the script that feeds the Portuguese version stays faithful to the original.

How it works

Japanese in, European Portuguese out, in four steps

01

Upload the Japanese video

Drop in up to 1 minute of MP4, MOV, or WebM. Keigo-heavy business Japanese and casual speech both transcribe.

02

ngram transcribes and translates

The Japanese audio, kanji and kana, is transcribed, then the script, captions, and on-screen text are translated into European Portuguese.

03

Review the European Portuguese version

Pick the pt-PT voice, confirm the o senhor or tu register, and keep the names and product terms the Japanese-to-Portuguese translation should preserve.

04

Export and publish

Export the European Portuguese cut for the Portugal and Lusophone channels, decks, and docs where the Japanese original could not go.
