Japanese AI Data Annotator | Model Evaluation & Quality Assurance

Native Japanese AI data annotator and model evaluator with fluent English, specializing in Japanese-language AI training data, multimodal evaluation, and quality assurance. I currently work on ongoing AI annotation and quality evaluation projects, covering image generation and image editing evaluation, audio transcription, proofreading, and Japanese text quality assessment. I am certified across multiple production workflows and regularly evaluate AI outputs using detailed quality rubrics. What I bring beyond task execution: • Native Japanese judgment I work from English-language guidelines and evaluate Japanese content at a native level, including culturally specific material where literal translation alone is not sufficient. • AI output evaluation experience I assess instruction adherence, visual and structural quality, linguistic accuracy, cultural relevance, and overall output quality across text and multimodal AI tasks. • Strong guideline discipline I work accurately from long, frequently updated specifications and identify ambiguity, edge cases, and overlapping criteria rather than making unsupported assumptions. • Japanese food and hospitality expertise Before moving into AI data work, I spent 20 years in the Japanese restaurant industry, including business and team management. This gives me practical subject-matter expertise when evaluating Japanese food, cooking, hospitality, and cultural content. I am currently completing the Google Data Analytics Professional Certificate and have also completed the Futures Thinking Specialization from the Institute for the Future / Coursera. Available 30+ hours per week for AI annotation, model evaluation, Japanese localization QA, data labeling, and related projects. Clear English communication and reliable turnaround.
