The National Institute for Japanese Language and Linguistics (NINJAL) conducts comprehensive research on the Japanese language to elucidate the variation within Japanese as well as the language-specific and language-universal characteristics of Japanese viewed as one of the world’s many languages. The long-term missions of NINJAL as an “inter-university” research institute are to facilitate the utilization of the results of this linguistic research in related fields, including Japanese language education, and to contribute to groundbreaking research in new fields involving human language.

During the academic years 2016–2021 (the Third Mid-term Plan Period), NINJAL aims to achieve the following two fundamental goals through a variety of collaborative research projects subsumed under the core research program “A New Integration of Japanese Language Studies Based on Diverse Language Resources.”

  • Joint Usage
    NINJAL develops a variety of large-scale resources (corpora and databases) for Japanese language studies and makes them available to universities, the scholarly community, and the general public.
  • Collaborative Research
    In cooperation with universities and research institutes in Japan and around the world, NINJAL plays a leading role in strengthening the international research network by conducting major collaborative research projects.


To achieve these goals, NINJAL has established a research department (organized into five divisions) and two centers, which work in close cooperation with each other.
