Old Japanese Old Japanese is the earliest attested stage of the Japonic languages, recorded primarily in eighth-century texts. It is documented in the Man'yōshū, Kojiki, and Nihon Shoki, and its study intersects with research on Chinese characters, Buddhism in Japan, Asuka period administration, and contacts with Baekje, Gaya confederacy, and Silla. Reconstructions draw on comparative work involving Ryukyuan languages, Middle Chinese, and inscriptions such as the Inariyama Sword.

Overview

Old Japanese appears in sources compiled under imperial auspices during the Nara period and reflects linguistic conditions in the Yamato Province court. Primary compilers and patrons include figures associated with the Tenpyō era, the Fujiwara clan, and court literati linked to the compilation of the Kojiki under Ō no Yasumaro and the Nihon Shoki under Prince Toneri. Philological traditions engaging with Old Japanese involve later scholars of the Heian period and modern linguists linked to institutions like the University of Tokyo and the Kyoto University historical linguistics departments. Comparative hypotheses have been proposed by researchers influenced by works on Middle Korean, Proto-Austronesian, and proposals connecting Japonic with Altaic-family hypotheses.

Phonology

Reconstruction of Old Japanese phonology uses the Man'yōgana system and glosses in the Manyoshu. Scholars debate vowel systems positing a six-vowel model versus alternative proposals; influential proponents include Bernard Karlgren and Samuel Martin with later revisions by Marc Miyake and Alexander Vovin. Consonant inventories are reconstructed with distinctions that reflect borrowing from Middle Chinese and potential substrate effects from Ainu languages contact theories. Prosodic features reconstructed include pitch accent patterns later observed in Tokyo dialect studies and Ryukyuan reflexes investigated by Shigeru Nakagawa and Hiroshi Nagashima.

Grammar

Old Japanese grammar exhibits agglutinative morphology comparable to later Classical Japanese and modern Japanese language dialects; verbal inflection categories and nominal case markers appear in the Man'yōshū and Nihon Shoki. Grammatical person and honorific systems implicate courtly practices associated with the Heian period precedent. The language shows vestiges of negative and interrogative constructions paralleling forms later codified in Kojiki glosses; discussions of morphological alignment have been advanced by scholars from Harvard University and University of Oxford comparative projects. Syntax analyses draw on parallels with Ryukyuan languages described by researchers at the University of the Ryukyus and studies of verbal morphology in publications from the Linguistic Society of Japan.

Writing and Orthography

Old Japanese orthography is chiefly attested in Man'yōgana, a logographic-phonetic use of Chinese characters employed in texts such as the Man'yōshū, Kojiki, and Nihon Shoki. The transition from Man'yōgana to kana scripts is traced through artifacts like the Ōmi no Muraoka inscription and sutra transcriptions associated with Prince Shōtoku patronage and Buddhist scholarship. Editorial and paleographic work by curators at the National Diet Library and the Tokyo National Museum has clarified orthographic variants; diplomatic collections include scrolls linked to the Tōdai-ji monastery and documents preserved in the Shōsōin repository.

Corpus and Texts

Key Old Japanese corpora comprise the Man'yōshū anthology, the Kojiki chronicle, and the Nihon Shoki histories, alongside inscriptions such as the Inariyama Sword and mirror inscriptions connected to household deities venerated at shrines like Ise Grand Shrine. Religious texts and sutra annotations produced by clerics attached to Hōryū-ji and Kōfuku-ji provide additional evidence. Later commentaries by Kūkai and Sugawara no Michizane preserved glosses used by modern editors at institutions including the National Institute for Japanese Language and Linguistics.

Historical Development and Descendants

Old Japanese develops into Early Middle Japanese and then into Late Middle Japanese, setting the stage for modern dialects such as the Tokyo dialect and the Ryukyuan branch comprising languages of the Okinawa Islands, Amami Islands, and Miyako Islands. Historical events influencing linguistic change include diplomatic exchanges with Tang dynasty China, migration and contacts with Korean Peninsula polities (Baekje, Silla), and internal court reforms under Empress Genmei and Emperor Shōmu. Comparative reconstruction efforts link Old Japanese to later standardization movements culminating in Meiji period language policy and orthographic reforms implemented by agencies like the Ministry of Education (Japan, 1871–1947).
