A real Korean version, not Japanese with Korean subtitles
A subtitle track leaves your Korean viewers reading along while the Japanese audio keeps playing underneath. ngram builds an actual Korean version instead: the Japanese speech is transcribed and translated, a Korean AI voice re-narrates it on the original timing, the captions are rebuilt in Hangul, and any Japanese titles or lower thirds on screen are re-set in Korean. Hangul reads best in short lines, so the caption text is wrapped to stay on screen and easy to follow.
It carries the register across, not just the words. Japanese leans on keigo to set politeness, and Korean marks the same thing through its honorific levels: a formal keigo script becomes proper formal Korean (존댓말) for a corporate or launch audience, while a relaxed, casual delivery can stay lighter. Clean studio narration and real meeting or stream recordings both transcribe reliably on the way in.
Korean AI voiceover
The narration is re-voiced in natural Korean with the right intonation for business or ads, timed to the Japanese original.
Hangul captions
Captions are translated into Hangul and re-timed, wrapped into short lines that stay readable on screen.
On-screen text
Japanese titles, callouts, and lower thirds come out in Korean, not left in the source language.
AI lip sync
Mouth movement adjusts to the Korean voiceover so a talking-head or presenter cut still reads as native.
Why Japanese teams translate video into Korean
Korean is the shortest hop across the Japan to Korea media and creator corridor, and it carries real commercial weight.
Reach a top-tier digital audience
South Korea is one of the most connected digital economies anywhere, and local-language video consistently outperforms subtitled content there. A Japanese demo, launch, or update becomes something Korean viewers actually watch instead of skim.
Show up the way Korean buyers expect
Korean versions of launch and support video signal real commitment to one of Asia's most brand-conscious markets. Japanese product, gaming, and B2B teams meet that bar with a Korean cut rather than asking prospects to follow Japanese audio.
Ride the Japan to Korea content cross-flow
Traffic runs constantly across the corridor, from anime and gaming to creator and corporate content. Japanese material already has a Korean audience waiting, and a Korean version is the highest-value next step for reaching it.
