This is a general index of the vocabulary, where all the words used in the “Soshijikarakuyoho”are arranged in the Japanese alphabetical order. The “Soshijikarakuyoho” is a scroll made around the middle of the Heian era (c.930AD), which has been preserved in an old temple called Ryuzoji located in Yoshiki, Yamaguchi City in Yamaguchi Prefecture. The scroll is written by kakuhitsu with letters and marks throughout all the volumes.
I carried out research on this book from beginning to end, and prepared a deciphered version of text. This index was made on the basis of these deciphered sentences. I shall be happy if this index can be of any help to study of the vocabulary used in the Heian era.
