&nbsp;Generally knows, Okinawa was extensively damaged from WW2. The air raid on Naha City 10<sup>th</sup> Oct. 1944 and ground battles destroyed Naha central area witheringly. After the war, there was few building to live. Okinawan people who came back from rural area and military draft needed to build their house. But at that time, GHQ and Ryukyu government had governed Okinawa until 1972. Okinawan local government could not use many of reconstruction projects and systems of Japan Central government. And worse more, not a small land of Okinawa including central area was grabbed up by USA military. So, some of people who could not return to their own residential lots had to move and rebuild their house another area, in most cases, next area or close area.<br>&nbsp;The high densely <i>Mawashi</i> district has built-up in above way. <i>Mawashi</i> district located the next area of the traditional central area where had not returned until 1952 (ref., Fig. 2), and so, there was rapidly crowded by returning people. But before the war <i>Mawashi</i> district was just a farming village where were not enough social infrastructures with narrow roads and poor road structure. It should be improved or developed before urbanized, but at that time Okinawa belonged to USA, there were not some appropriate development systems and projects.<br>&nbsp;This study aimed to identify the period of each districts build-up, and then analyze the relationship between each districts character with road patterns and each districts period. In view of the change of the Okinawan political system after WW II and built-up background, there are 4 aspects, as like 1)prewar traditional settlement, 2) forced settlement, 3)sprawl district without planning guideline, and 4) development permission district(ref., Fig. 7). The research methods are 4, research the historical document to identify the pre-war settlement district, tracing the road position specification of Naha city to distinguish roads and areaways, listed up the development dates from official development permission ledger after 1974 to define planning districts and sprawl area and field survey of each district to find the typical problems of the district. The problematic road networks are found 5 patterns in this area by the field survey. These are a) small crowded building district without jointing roads, b) small crowded building district jointing dead-end road of article 42 -2, Japan Building Act, c) small crowded building district jointing not well network roads of article 42 -2, Japan Building Act, d) small crowded building district jointing well-formed roads of article 42 -2, Japan Building Act, and e) development permission accepting district with not well network road to main roads(ref., Table 2).<br>&nbsp;As results, these a)-e) patterns are mixed in each 1)-4) periods also, but 3) is the most serious condition in problematic road networks, decrepit buildings, and prevention of disaster. Considering the physical condition data of districts, 2) is assumed to have a singular aspect.
