What Studio Ousia does
Studio Ousia is a Japan-based natural language processing (NLP) and large language model (LLM) company founded in 2007, headquartered in Otemachi, with a headcount of 11-50 employees. The company develops multilingual NLP technology focused on transforming unstructured enterprise text into usable organizational knowledge, with particular emphasis on Japanese-language and cross-lingual contexts. Its core technical differentiator is the ability to recognize and embed internal and industry-specific terminology into language models, addressing a known weakness of generic LLMs in enterprise search and retrieval-augmented generation (RAG) settings.
