About me
I'm Kozy, and I provide Japanese voiceover services, AI training & Japanese business support. You can find my Japanese AI voice on the major AI voice websites such as ElevenLabs. In addition, I participated at xAI as a sound engineer for AI training, and at Outlier as a Japanese AI trainer in 2025. I've worked with various companies and YouTubers, and I've even been in anime. For example, I did the Japanese dub for the latest Angry Birds animation, Mystery Island. I also run a Japanese voiceover agency called Just Global Media. We can arrange voice talent of all ages and genders.... Read more

Curated Talent Agency: JGM represents a hand-picked network of Japan’s top professional voice actors and narrators, enabling us to provide diverse vocal profiles for any scale of project. Multilingual Support: Beyond Japanese, we offer professional narration in English, Chinese, Korean, and other major languages to meet global demands. Full Post-Production: We offer end-to-end services, including professional translation and precise video synchronization (dubbing). AI & Innovation: We are at the forefront of AI development, providing high-quality Japanese voice datasets for AI training. Koji’s professional voice clone is also available via ElevenLabs for scalable digital solutions. Why Partner With Us? With a unique background in both finance (CPA) and media (Radio), our founder ensures that every project is handled with business-level precision and creative excellence.
