The Corpus of Historical Japanese (CHJ) is being developed as a basic resource for research into the history of the Japanese language conducted in the digital age. As the "readings" (pronunciations), part-of-speech classifications, and morphological information are provided for all of the texts, the corpus not only can serve in place of the traditional concordances but can also be used for more advanced searches and statistical analyses.
It is our goal in the future to make the CHJ into a diachronic corpus that covers the whole historical range of the Japanese language, including texts in Old Japanese (the oldest attested form of the Japanese language), but at present we have published the following series as one part of the projected whole: Nara I (Man'yō-shū), Heian, Kamakura I (Forktails and Essays), Kamakura II (Diaries and Travel Literature), Muromachi I (Kyōgen), Edo (Sharebon pilot version, Ninjō-bon pilot version), Meiji Era-Taishō Era I (Magazines). For access to the contents currently in publication, please see the pages under the links below. Users will need to access the contents through the online search engine Chunagon. Completion of a Users Licensing Agreement (separate from that for the online publication of the Balanced Corpus of Contemporary Written Japanese) is required.
