Eastern Old Japanese (abbreviated as EOJ; Japanese: 上代東国方言, 上代東国語) is a group of heterogenous varieties of Old Japanese, historically spoken in the east of Japan, in the area traditionally called Togoku or Azuma.
Classification
Eastern Old Japanese constitutes a branch of the Japanese subgroup of the Japonic languages (Insular Japonic), with the other varieties of Old Japanese, which all descend from proto-Japanese (separate from Proto-Ryukyuan, following the classification used by Kupchik (2011).[1]
Attestations
Eastern Old Japanese is mainly attested through poems collected in several anthologies written during the 8th century:[2][3]
Man'yōshū (万葉集), in the fourteenth and twentieth volumes, as well as some poems from volume sixteen ;
Kokin wakashū (古今和歌集), of which a poem is written in this dialect (written during the Heian period) ;
All this would give a total of 242 short poems and one long poem according to Alexander Vovin (2014).[6]
Geographic distribution
This variety is geographically opposed to Western Old Japanese and Kyūshū Old Japanese.[7][6] It was spoken to the east of Nara, the capital of Japan during the Nara Period, approximately in the current Kantō region, Chūbu region and Tōhoku region (then collectively referred to as the Azuma region).[8][9]
Varieties
Eastern Old Japanese was not a unified variety but a collection of different dialects. Their demarcation differs depending on the author.[10]
For example, Bjarke Frellesvig (2010) distinguishes three dialect areas:[11]
He states that these dialects form a continuum with the varieties of Nara Old Japanese, with North Eastern Old Japanese constituting the most divergent variety.
However, the majority of songs and poems do not have information on their provenance.[11]
John Kupchik (2023) calls all of these varieties Azuma Old Japanese, consisting of two dialects: Töpo-Suruga Old Japanese in the three provinces of Frellesvig's southern area and Eastern Old Japanese in the rest.[12] The former dialect lacks attested Ainu loanwords.[13]
He remarks on the differences in the spelling of the two varieties.[14] In earlier work, he had separated the dialects of Shinano province as Central Old Japanese due to the absence of innovations shared with his Töpo-Suruga and Eastern Old Japanese groups.[15]
Typology
Eastern Old Japanese is a SOV language[a] with a structure including a modifier at the start of the sentence, although there are exceptions. There are many suffixes, but unlike most SOV languages, there are also prefixes.
There exists a correspondence between the Western Old Japanese *i and *u and the Eastern Old Japanese *(j)e and *o respectively, which is confirmed by the comparison of the three Japanese dialects, as well as the Ryukyuan languages. Thus, the Eastern Old Japanese vowel system would have been closer to that of Proto-Japonic than that of Western Old Japanese.[16]
Vocabulary

The Eastern Old Japanese lexicon is mainly inherited from Japonic languages. However, it is also contains Koreanic and Ainu loanwords, and only a few of Sinitic origin.[17]

Extinction and descendants
The dialects of Eastern Old Japanese were replaced by the Kyoto dialect (Middle Japanese), the descendant of Western Old Japanese during the Heian period (between the 8th and the 12th centuries).[18] However, there are still modern traces of this variety:
The relic language Hachijō, spoken on the Izu Islands but on the verge of extinction. Eastern Old Japanese and Hachijō have common characteristics not found in other branches of the Japonic family.[18]
Modern Eastern Japanese dialects contain traces of a substrate, such as the verb sugos- 'to exceed' (comparable to Western Old Japanese sugus-, of the same meaning), the imperative suffix -ro, the predicative suffix -ke on adjective verbs or -o on verbs, among others.[19]
Relation with the Ryukyuan languages
According to Maner Lawton Thorpe (1983), the phonological correspondences of Eastern Old Japanese shared with the Ryukyuan languages could be explained by the descend from a common language. Thus, he proposes the following phylogenetic tree:
Following his model, Western Old Japanese would have separated first, during the 4th-5th centuries, then the Kyūshū-branch would have separated three or four centuries later. Subsequently, Kantō would have been populated by Japonic speakers directly from Kyūshū, without passing through central Japan.[20][21]
However, Alexander Koji Makiyama (2015) finds the results of diachronic changes in Eastern Old Japanese such as in denasalization, fortition and vowel raising unconvincing in comparison with the Ryukyuan languages. In fact, he finds:
12 attestations in Eastern Old Japanese of denasalization which could be attributed to Proto-Ryukyuan, but 10 of them actually correspond to the possessivecase marker-ga ;
fortition is only attested in two forms in Eastern Old Japanese, compared to only one in Proto-Ryukyuan, *bakare, in addition to the fact that it may be a loan;[b]
regarding vowel raising, the change from Proto-Japonic *ə to *o in Proto-Ryukyuan makes certain reconstruction impossible. Only four forms in Eastern Old Japanese could correspond to the Proto-Ryukyuan form.
The hypothesis of a linguistic contact or a resemblance is therefore, in the state of current knowledge, only speculative.[22] Thomas Pellard (2015) also considers that this hypothesis is unproven.[23]
