Freelancer specializing in Japanese writing and AI evaluation.
What I'm looking for
I am a dedicated freelancer with a strong background in Japanese writing and evaluation of AI-generated content. My experience includes assessing the naturalness and appropriateness of the Japanese language, ensuring that honorifics and formal expressions are used correctly. I take pride in my ability to review and evaluate Japanese text for grammar, clarity, and linguistic correctness, which has been crucial in delivering high-quality content to my clients.
Before my freelance career, I worked as a production director at Fines Co., Ltd., where I was responsible for YouTube advertising. My role involved narration and scenario writing for advertisements, as well as managing the production process. I successfully led meetings with clients and outsourced companies, which resulted in effective product promotions and recruitment campaigns. My ability to conduct concise and high-quality meetings has always been a priority, ensuring customer satisfaction and project success.
