Language Change Division


The Language Change Division aims to elucidate the historical development of Japanese from a comprehensive perspective including dialectal variation of Present-day Japanese. For this purpose, a project for building a historical corpus of Japanese is underway that is intended to cover all the stages of earlier Japanese from the Nara era to the Meiji and Taisho eras. It is expected that the historical corpus, together with a variety of related databases published by NINJAL, will open a new horizon on diachronic studies of Japanese in the future.
