The results of this study were obtained from an investigation of the archives of silk production in relation to the tax on silk during the Nara period in the 8th century. The silk producing districts ranged from the Kanto region to Shikoku and Kyushu, and there were over 40 silk producing districts in the middle of the 8th century. Three main kinds of silk were produced, namely Ashiginu fabrics, silk fiber and floss silk, and there were 15 districts producing Ashiginu fabrics (42%). The districts producing the largest amount of silk annually were Echu (floss silk), Inaba (Ashiginu fabrics, silk fiber and floss silk) and Iwami (floss silk). The districts that were the largest annual producers of the three different types of silk were Mikawa (Ashiginu fabrics), Inaba (silk fiber) and Echu (floss silk). Mulberries were cultivated in Echu district in 759 A.D. and this was the only example of mulberry field cultivation in the Nara period. Two hamlets in the Echizen district in 740 A.D. were the only locations where sericulture was practiced in the Nara period. These were produced against the tax of silk by Ashiginu fabrics and floss silk. And the weights of these products were 2.4 and 1.8kg, respectively, and the used cocoon weights were 40 and 30 kg, respectively, from a trial calculation for harvesting cocoons. Moreover, the total harvesting cocoon were about 80 and 90 kg by addition to Ashiginu fabrics. (E mail: mutsuo_miki@yahoo.co.jp)
