Czech to Japanese

Translate Czech Video to Japanese

Take a Czech recording and get a Japanese one back, with Japanese AI voiceover, translated captions, Japanese on-screen text, and lip sync. Czech automotive suppliers, glassmakers, machinery firms, and breweries use it to reach Tokyo buyers, and Japanese carmakers running Czech plants send Japanese cuts up to headquarters. Upload up to 1 minute and confirm the keigo register before export.

What gets translated

A real Japanese version, not Czech with Japanese subtitles

Subtitling a Czech video leaves your Japanese audience reading while the Czech audio plays underneath. ngram builds an actual Japanese version: the Czech speech is transcribed and translated, a Japanese AI voice re-narrates it on the original timing, the captions are rebuilt in Japanese, and any Czech titles or lower thirds on screen are re-set in Japanese. The scripts are worlds apart, Czech in Latin letters with háček and čárka marks on č, ř, and ě, Japanese in kanji, hiragana, and katakana, so the captions are laid out for CJK text with short lines and no mid-word breaks.

It carries the register across, not just the words. Czech marks formality through grammar, the polite vykání address and its 7-case declension for a B2B or industrial audience, the casual tykání for something lighter, and that maps onto Japanese keigo for the formal read or plain form for the informal one. A precise engineering script from Plzeň lands as proper keigo, while a relaxed creator clip can stay in plain form.

Japanese AI voiceover

The narration is re-voiced in natural Japanese with business-appropriate keigo, timed to the Czech original.

Japanese captions

Captions are translated and re-timed, with CJK lines kept short and without mid-word breaks so they stay readable.

On-screen text

Czech titles, callouts, and lower thirds come out in Japanese kanji and kana, not left in the source language.

AI lip sync

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

Why Japanese

Why Czech teams translate video into Japanese

Japan is a high-value, language-first market, and the Czech to Japan corridor runs through cars, machinery, and glass.

01

Reach the world's third-largest ad market in Japanese

Japan is the world's third-largest advertising market and rewards content made in Japanese. A Czech automotive supplier or machine-tool maker that already produces polished product video reaches Tokyo buyers far better when that video speaks Japanese than when it asks them to follow a foreign-language cut.

02

Onboarding Japanese teams expect in their own language

Japanese buyers and staff expect onboarding and support video localized for them, and content left in another language stalls adoption. Czech engineering and software firms whose training recordings transcribe cleanly can turn each one into a Japanese version their distributors and end users actually work through.

03

One Czech recording covers the Tokyo reporting line

Japanese carmakers run large plants in the Czech Republic, and their line walkthroughs, safety briefings, and updates are recorded on site in Czech. A faithful Czech transcript becomes a Japanese cut headquarters in Tokyo can review, so the same footage serves the floor in Bohemia and the boardroom in Japan.

How it works

Czech in, Japanese out, in four steps

01

Upload the Czech video

Drop in up to 1 minute of MP4, MOV, or WebM. Clean Czech narration and on-site recordings both transcribe on the way to Japanese.

02

ngram transcribes and translates

The Czech audio is transcribed, then the script, captions, and on-screen text are translated into Japanese kanji, hiragana, and katakana.

03

Review the Japanese version

Pick the Japanese voice, confirm keigo or plain form, and keep the names and product terms the Czech-to-Japanese translation should preserve.

04

Export and publish

Export the Japanese cut for the Tokyo channels, distributor decks, and docs where the Czech original could not go.

FAQ

Czech to Japanese translation, answered

The narration is re-voiced with Japanese voices that carry business-appropriate keigo, timed to your Czech original. You choose the voice and can set a keigo or plain-form register before export.
