Why Video Needs Localization
Japanese users overwhelmingly prefer content in their native language — especially video.

But English-language videos, even with subtitles, underperform across Japanese platforms.

    YouTube users in Japan
  • over 70%
    of the Japanese population has limited or no working proficiency in English
  • 2–3×
    higher engagement compared to subtitled or untranslated video.
