Central vowels are observed both in the Ryukyuan dialects and East-northern dialects of the Japanese language. This paper takes notice of the u-fronting preceded by the coronal consonants which were observed in the 16th century dialect of Okinawa main island. It is speculated that this kind of coarticulation also was a trigger change toward the centralization of [u] vowel of East-northern dialects of Japanese. Just as the coronal consonants influence the shape of the tongue body by u-fronting, it is also supposed that the shape of the tongue pronouncing [i] could also be assimilated to the preceding coronal consonants. As the results of the above two assimilations, firstly /i/ and /u/ are speculated to have begun centralization in the environment following /s, z, c/. Secondly the consonants preceding central vowels have extended to all the consonants other than /s, z, c/, and thirdly /i/ and /u/ following /s, z, c/ have ceased to be distinct phonemically.

The South Ryukyu dialects are divided into two categories: one of which basically has three vowels /i ・ a ・ u/, and the other, four /i ・ ï ・ a ・ u/. The former is assumed to be derived from the latter by the decline of the neutral vowel /ï/. This neutral vowel has been interpreted and transcribed differently in phonetic notation by many researchers, e.g., [ï, ɨ, 〓]. The purpose of this article is to analyse the acoustic substance of these neutral vowels, using the digitized phonetic sources of the Aragusuku dialect as reported in Kuno et al. (1993), and the Karimata dialect and Oogami dialect as reported in Oono et al. (1998). According to Imaishi (1997), the characteristics of the neutral vowel can be seen from examination of F2. Although the distribution of F2 of the neutral vowels in all of these dialects locates between [i] and [u], the values of F2/F1 differ significantly among these dialects. This is supposed to be affected by the difference of articulatory position of the vowels in question. The value of F2/F1 of Oogami dialect is especially low, and in part overlaps with that of [u]. This means that the tongue position of the neutral vowel in Oogami is very close to that of [u]. Presumably, the distinction between the two vowels depends on the configuration of the lips, spread vs. round.

近代日本の国語政策をG.Thomasによる純化論の観点から類型化した上で、明治期の国語調査委員会及び文部省による標準語政策は第一次世界大戦前のヨーロッパの帝国的国家語を志向した改革的純化論に当たるものとして位置づけられること、大正・昭和期以降の柳田国男を中心とする民俗研究における国語観は第二次世界大戦後のヨーロッパ新興国家の国語観を意識した民俗的純化論であったこと、さらに、標準語教育が破綻した学校教育現場で地域方言を郷土を象徴する教材としてとらえるようになったことを明らかにし、これらの民俗的純化論の姿勢が戦後の民主的な共通語政策の前提となっていったことを歴史的に明らかにした。

The central vowels in the Northern Ryukyu dialects are historically thought to have been formed by the following four processes: (I) centralization of the vowel [e], (II) centralization of the vowel [u] following the consonants [s・z・c], (III) the coalescence of diphthongs [ai・ae] and IV) the assimilation to the central vowel in an adjacent syllable. Among these, process II brought about the condition of the so-called "Hitotsugana-ben" throughout most of the Ryukyu dialects except the Northern Amami dialect. So the absense of process II can be considered one of the remarkable characteristics of the Northern Amami dialect. Again, the proto-condition for process I, prevalent in all dialects of the Amami regeon, and process II must have included such a contrast as ^*Ci/Ce/Cu (C=s,z,c). This contrast can be interpreted to have changed into the following situations present in current Northern Amami dialects: (1) Ci[i]/Ce[ï]/Cu [u] observed in Yoro, (2) Ci[i]/Ce = Cu[ï] observed in peripheral area of Ooshima, Ci=Ce[i]/Cu[u] observed in Kikai, Ci = Cu[ï]/Ce[i] observed in north part of Tokunoshima, and (3) Ci = Ce = Cu[ï〜i] observed in Naze and often refered to as "Hitotsugana-Ben". Historically (1) is considered to be the oldest situation. This was followed by (2), which was brought about by the merger of the various parts of (1). Lastly, stage (3) was brought about by the merger of the remaining independent part of (2).

近代国語観の変遷に関して、各地に散在する全国各県の地方教育会資料から方言関係記事を抽出した戦前期地方教育会雑誌方言関係記事データベース(PDF形式1527ファイル)を作成した。戦前期地方教育会資料が収載された膨大な方言情報の活用に関して、岩手県郷土教育資料(昭和11年・15年)に反映した岩手の小学校教師たちの草の根的な国語観を分析した上で、岩手県郷土教育資料に収載された14681点の方言情報についてデータベース化を行い、これを活用して昭和初期の岩手県方言地図の電子的復元を試行した。これらの研究成果の報告会を岩手県立図書館と共催で開催した。
