Manyoshu and Hachidaishu in the Corpus of historical Japanese ver. 2019.3

The National Institute for Japanese Language and Linguistics is developing and publishing the Corpus of historical Japanese (CHJ) as basic data for the study of Japanese language history in the digital age (https://pj.ninjal.ac.jp/corpus_center/chj/).  The corpus is updated two times a year, and the latest edition published in March 2019 newly released the corpus of Hachidaishu (eight imperially commissioned anthologies of waka poetry starting with Kokin wakashu and ending with Shinkokin wakashu) as a part of the CHJ. In this corpus, there are links to the images of the Shōho hanpon nijuichidaishu (正保版本二十一代集) by the National Institute of Japanese Literature and the text of the Shin Nihon koten bungaku taikei (Iwanami Shoten, Maruzen eBook Library edition), and users can refer to the original images and annotations (https://pj.ninjal.ac.jp/corpus_center/chj/wakashu.html).

As for the corpus of the Manyoshu which has already been released, links to the relevant poetry of Oxford-NINJAL corpus of old Japanese and Manyoshu kohon database (万葉集校本データベース) have been newly added to enable viewing of syntactic structures, original text images, etc. (https://pj.ninjal.ac.jp/corpus_center/chj/nara.html)
As a result, the corpus for the Wakashu (collection of Japanese poetry) from the Nara period to the Kamakura period was improved, and it became easy to study the diachronic changes in the use of language in the anthology of Japanese poetry and to compare it with prose works.
