Localize Japan: Localize videos to grow across YouTube and global markets

Hi Product Hunt 👋 I built Localize Japan to help creators and growth teams turn one video into natural localized content for new markets. Most localization tools still feel too literal, too robotic, or too fragmented. You might get subtitles from one tool, dubbing from another, and metadata from somewhere else — but the final result still doesn’t feel native. Localize Japan is designed to make that process feel much more natural by combining: - AI dubbing - localized captions - localized metadata - a workflow built for video growth, not just translation The initial use cases I care most about are: - YouTube creators who want more views and subscribers from new language markets - marketers who want to test winning video creatives internationally Right now I’m focused on making localization feel more natural, more usable, and more growth-oriented. I’d love to know: - Would you use this more for YouTube growth or for ad testing? - Which language pair would matter most to you first?
