The purpose of this study is to find the problems caused by the United States military base in Okinawa pref. focusing Allotted Land Law (Wari-ate-tochi Law). This law was enacted in 1951 by the U. S sovereighty. We firstly review the historical process of Allotted Land Law. Secondly investigate the actual conditions in two districts, in Urasoe City. We find that the land-owners have complain on the Allotted land and disagree with lease holders about the use of their lands. As that result, many old houses remain still in the Allotted Land area. We conclude that local and central governments should have responsibility to solve special structural problems caused by the U. S military base.
