This article describes the actual conditions in the colonial management of the Amami Islands by the Satsuma feudal domain. I have studied, frommultifaceted perspectives, “the Oshima kibocho” proclaimed as the administrative regulations in the Amami Islands in Kyoho 13 （1728）. Thisstudy is based on the following historical processes: the Amami Islands were a territory of the Satsuma feudal domain from Keicyo 14 （1609）when the Ryukyu Kingdom was conquered by the Satsuma feudal domain; the fi rst statutes ruling the Amami Islands, “the Oshima Okime jou jou,”were proclaimed in Genna ９ （1623）; and many detailed prohibitive regulations were proclaimed since those fi rst statutes.“The Oshima kibocho” was proclaimed more than 100 years after the proclamation of “the Oshima okime jou jou”. Various “Kibocho（administrative regulations）” and “Oboe （memorandum）” proclaimed after the proclamation of “the Oshima okime jou jou” were most likely integrated into “the Oshima kibocho”. That is, the people of the Amami Islands did not follow “the Oshima okime jou jou”. “The Oshima kibocho” is fi lled with enormous numbers of prohibitive regulations and orders, amounting to 149 articles. These regulations and orders stipulate the lives of islanders from birth to death. In addition, the colonization of the Amami Islands by the Satsuma feudal domain was completed by proclamation of “the Oshima kibocho”. Importantly, proclamation of “the Oshima kibocho” evoked a reign of terror in the form of the sugar monopoly, which was adopted by theSatsuma feudal domain to control all sugar produced on the Amami Islands when the Satsuma feudal domain suff ered fi nancial collapse due tothe debt of ５ million ryo （currency unit at the time） at the end of the Tokugawa shogunate.
