The "Bibliographic Database of Research on Japanese Language and Japanese Language Education" is a database of research material related to the Japanese language and Japanese language education. The catalogue reflects the data in the Japanese Language Studies Annual Survey and Bibliography 『国語年鑑』and the Japanese Language Education Annual Survey『日本語教育年鑑』which were published by NINJAL, and contains searchable articles and books on these topics published in 1950 onwards. New data is being added subsequently. Please refer to the Database Overview for more information.
