Why Japanese subtitles matter
Japanese is spoken by 125 million people, primarily in Japan — the world's third-largest economy and a major hub for technology, gaming, anime, and entertainment. Japan has one of the highest per-capita content consumption rates globally, and Japanese audiences strongly prefer content in their native language. Adding Japanese subtitles is critical for reaching this valuable, engaged market.
