石塚龍麿と橋本進吉 : 上代特殊仮名遣の研究史を再検討する  [in Japanese] What Does HASHIMOTO Shinkichi OWe ISHIZUKA Tatsumaro for the Study of Two Types of Man'yogana?  [in Japanese]

万葉仮名の二類の書き分け(上代特殊仮名遣)の存在と,それが音韻の区別に基づくことは,本居宣長・石塚龍麿などがすでに述べていることで,"橋本進吉がのちに宣長・龍麿とは無関係に独立して発見した"との説は認めがたい。橋本がはじめ,"ヌに二類あり,『古事記』ではチにも二類あり"としたのは,龍麿の『仮字遣奥山路』に基づくものである。宣長・龍麿が認めた『古事記』のモの二類の区別を橋本がのちに否定したためこの区別の再確認を行なった池上禎造・有坂秀世は,その過程で『韻鏡』の利用や「音節結合の法則」などから,上代特殊仮名遣が音韻の区別に基づくことを明確にしたのであった。

Scholars in Japan believe that HASHIMOTO Shinkichi first discovered the distinction between two types of man 'yogana, the so-called korui-type and otsurui-type, and that he was the first to describe the phonological background of the two types. In fact, ISHIZUKA Tatsumaro, a student of MOTOORI Norinaga, had already distinguished these two types in detail in his Kanazukai oku no yamaji at the end of the 18 th century. HASHIMOTO Stated that he discovered the distinction between the two types, while confessing that he had read ISHIZUKA's book before he began his study of that distinction. Indeed, HASHIMOTO repeated ISHIZUKA's errors : he distinguished the syllable nu in two ways and also distinguished the syllable ti in two ways only in Kojiki. However, MOTOORI and ISHIZUKA had already discovered the phonological back-ground of these two types before HASHIMOTO carried out his phonological research in detail.
