Japanese video translator: Dub videos to Japanese with AI

Sign up free on Fliki. Upload an MP4, MOV, MP3, or WAV (up to 20 MB), or paste a script. Japanese is pre-selected as the target language on this page. Pick a native Japanese voice and dialect, then export 1080p MP4 with translated voiceover, captions, and on-screen text.

Yes. Fliki is bidirectional. Upload Japanese audio or video and translate it to English, or to any of the 80+ other supported languages. The AI transcribes the source Japanese, translates the script to your target, and re-renders with a native-quality voice in the target language.

A curated library of neural Japanese voices covering major dialects, with adjustable pace, pitch, and emotion per scene. Preview voices on the page or in the editor before generating your video. New voices are added regularly.

Yes, when Japanese is one of our supported clone-language pairs (currently 30+). Upload a 30-second sample of your own voice. Fliki clones it with high accuracy. Use your cloned voice to dub every video into Japanese for personal-branded multilingual content.

Both. The audio is re-rendered with a native Japanese voice AND captions are auto-generated synced to the new voiceover. Lower-thirds, slide titles, and on-screen labels also translate to Japanese — not just the spoken voice — so the localized video looks made for Japanese speakers, not retrofitted.

Fliki uses state-of-the-art neural translation models trained on large-scale Japanese corpora, achieving native-fluent quality for most general content. For specialized vocabulary (legal, medical, regional slang), edit any translated line in the script editor before exporting. The AI provides the draft, you keep editorial control.

Yes. Download the source MP4 and upload it to Fliki, or paste the YouTube transcript into the script tab. Fliki translates and dubs in Japanese, then exports a YouTube-ready 1080p MP4 in 16:9. Useful for running Japanese-language YouTube channels off one source video.

Yes. Free forever plan with monthly credits, no credit card required. Free exports include a small Fliki watermark. Paid plans remove the watermark, unlock voice cloning, AI avatars, longer videos, batch translation, and 4K export.

Yes. Upload an MP3 or WAV and Fliki transcribes, translates, and re-renders the audio in Japanese. Useful for podcast localization, voiceover dubbing, and audiobook translation. Export as MP3 audio or as video with optional waveform/cover-art visuals.

Where regional dialects of Japanese differ meaningfully (accent, vocabulary, regional usage), Fliki includes multiple voices per dialect. Pick the dialect that matches your target audience — local-region native, diaspora-friendly neutral, or formal/broadcast tone.

Translations generated on paid plans are royalty-free and commercially usable, including AI voiceover, dubbing, and translated captions. Free plan exports include a small watermark. Always confirm rights for your source video before translating.

Most short-form videos (under 60 seconds) translate end to end in 2 to 5 minutes. Longer videos and batch multi-language translations scale linearly. A 5-minute video into Japanese typically takes 5 to 10 minutes including the script translation, voice rendering, captions, and final export.
