masahiro nakatsugawa PRO

AI architect and researcher focusing on Japanese language models, embeddings, RAG, and applied AI systems. My work spans Japanese semantic analysis using Ruri, domain-specific LLMs, synthetic dataset generation, AI-driven marketing intelligence, multilingual news analysis, and cultural knowledge systems. I am particularly interested in embedding model evaluation, fine-tuning, semantic clustering, knowledge representation, and the integration of LLMs into production applications. I also work on AI-assisted software engineering, evaluation frameworks, and AI governance, with a focus on building reliable and practical AI systems.
