I will create accurate native japanese subtitles for your video
Seijiro Y
About this gig
I'm a native Japanese speaker and an app developer. I create natural, native Japanese subtitles for your video, and because I work with files and formats every day, I keep the SRT timing, line breaks, and reading speed correct so the subtitles sit right on screen.
I use AI to transcribe and draft quickly, then review every line myself as a native speaker for accuracy, tone, and natural phrasing. You get a clean SRT file (or burned-in on request) with a QA report on timing and readability.
On direction: English to Japanese is my native strength. For Japanese to English, I understand every nuance of the Japanese source and deliver accurate, natural English, reviewed carefully rather than machine-dumped.
Great for YouTube, product videos, courses, anime and VTuber clips, and app demos. Send your video or a link and tell me the languages, and message me first for a quick quote on longer videos.

I'm a native Japanese speaker and an app developer. I localize apps and games into natural, native Japanese without breaking your code. Because I read i18n files every day, I keep every placeholder, tag, and ICU plural intact, then review each line as a native speaker for accuracy and natural tone. You get AI-accelerated speed with genuine human quality, plus a QA report with every delivery. I work with JSON, .strings, and CSV, and return your file with its structure unchanged and ready to ship.
FAQ
Do you use AI?
I use AI to transcribe and draft, then review and edit every line myself as a native Japanese speaker and check the timing by hand. You get AI speed with real human quality, never a raw machine dump.
