Phonology
Proto-Japonic words are generally polysyllabic, with syllables having the form (C)V.
Consonants
The following Proto-Japonic consonant inventory is generally agreed upon, except for the values of and (see below):
Scholars agree that the Old Japanese voiced consonants ''b'', ''d'', ''z'' and ''g'', which never occurred word-initially, are derived from clusters of nasals and voiceless consonants. In most cases, the two consonants were brought together by loss of an intervening vowel. A few words display no evidence for a former vowel, and scholars reconstruct a syllable-final nasal of indeterminate place preceding the voiceless obstruent, as in > Old Japanese > Modern Japanese 'grain', > OJ > MJ 'knee'. These nasals are unrelated to the
moraic nasal of later forms of Japonic, which derive from contractions or borrowings from other languages such as

The other Old Japanese consonants are projected back to Proto-Japonic except that authors disagree on whether the sources of Old Japanese ''w'' and ''y'' should be reconstructed as glides and or as voiced stops and respectively, based on Ryukyuan reflexes:
* Southern Ryukyuan varieties have corresponding to Old Japanese ''w'', e.g. Miyako 'I' and Yaeyama 'stomach' corresponding to Old Japanese and . Two dialects spoken around

The other vowels of Old Japanese are believed to derive from sequences of Proto-Japonic vowels, with different reflexes in Ryukyuan and Eastern Old Japanese:

Regardless of their values, the different tone patterns in the group words into accent classes that generally correspond to those obtained by comparative reconstruction from modern mainland Japanese dialects.
In contrast, Ryukyuan languages share a set of accent classes that cut across the mainland classes.
For example, for two-syllable nouns, the has five accent classes, which are reflected in different ways in the major accent systems of mainland Japanese, here represented by Kyoto, Tokyo, Oita and Kagoshima. Ryukyuan languages, here represented by Kametsu (the prestige variety of the

), show a three-way division, which partially cuts across the five mainland classes. In each of the modern varieties, the pattern of high and low pitches is shown across both syllables and a following neutral particle.
Thus seven classes of disyllabic nouns are required to account for the various reflexes.
In some Ryukyuan dialects, including Shuri, subclass (a) is marked by a long vowel in the first syllable instead of a distinct pitch pattern, which led Hattori to suggest that the original distinction was one of vowel length.
