Corpus of historical Japanese (2018)
At the National Institute for Japanese Language Studies, we are constructing the "Corpus of Historical Japanese " as a diachronic corpus where you can study the history of Japanese from the Nara period to the Meiji and Taisho eras. This corpus enables advanced search by annotating word information to the whole sentence. It can be used online through the search service "Chunagon" (https://chunagon.ninjal.ac.jp) for free of charge.
