Abstract
This kiwari Text (architectual reference book) "DAIKU-MASUZUMI-KANAJAKU-NO-SHIDAI" was introduced by the late Mr. Inui in 1961 in the Book written about Japanese technology of pre Meiji period. From the contents itself this Text was determind to be of Middle Ages (written before Edo period). Recently studies of kiwari texts especially of Middle Ages are making progress. This kiwari Text is used as one of the important indexes. However introduced contents of the Text by Mr. Inui was not original (original is missing), but seems to be selected and translated into modern expressions. Besides this translation is based on the knowledge of kiwari system of Edo era, so it is quite natural we find some contradictions and questions. Therefore there are many difficulties when we take this Text as original. From this point of view this paper examines the Text comparing with that of the same age and tries to restore the missing original One, as well as examines kiwari system of Middle Ages.
