More than 75,000 emergency houses, called the standard prefabricated house, were built in Okinawa after the war in approximately four years, beginning in 1946, which made a great contribution to reconstruction. The standard prefabricated house was designed by a local architect named Hisao Nakaza (1904-1962) at the U.S. naval military government Okinawa public works department on Nov. 30, 1945. The purpose of this study is to clarify the details of the situation about the process, the design and the supply system of the standard prefabricated house, and to also clarify the actual factor of the massive and quick supply. This paper consists of five chapters. Chapter 1 describes the background based on the career and articles of Nakaza and why he began to design the standard house. According to his career, he had experience with evacuation house construction in wartime. After the experience was evaluated, Nakaza designed the standard house at the U. S. naval military government Okinawa public works department. Chapter 2 considers the standard house plan situation of the U.S. naval government from directions. The naval government gave orders that let local people resettle from camps to their original places of residence on October 23, 1945. Therefore, the government had to supply houses. The direction of October 31, 1945 shows the design guide of the houses. It is thought that the scale and materials of the standard prefabricated house were decided based on this. Chapter 3 analyzes the design drawing. The standard prefabricated house responded to the situation of a lack of engineers in that the frames of the walls and roof trusses were designed as prefabs which were produced at a factory. Furthermore, the design can respond to the lack of material flexibly, and the choice of finishing materials depending on the local situation is possible. Chapter 4 investigates Nakaza's article and the Okinawa public works department relations documents, and understands the supply system. For approximately four months, from January to May in 1946, the constructions were instructed by three people, including Nakaza. From the period of May, 1946 to the end of 1949, constructions were carried out by an organized system by the public works department of Okinawa civil administration. The department was able to settle the U.S. government budget directly. Architectural division managed the material yards and carried out construction by construction units. In addition, motor pools of the land transport division took transports. Chapter 5 analyzes the monthly construction number on the activity reports of the U.S. military government and assumes the construction end time. Construction was carried out most actively during the periods from the beginning of 1946 to mid 1947. The first action system was good; more than 4,000 houses a month in December, 1946 and January, 1947 were built. There are construction reports until October, 1949, which show that the houses were built until about the end of 1949. A total of about 76,815 houses were supplied within four years, from January, 1946 to October, 1949. As above, the standard prefabricated house was designed by architect Hisao Nakaza, and supervised by the U.S. military government, and managed by local government, and constructed by mutual support among residents. The main reasons to be able to serve a large quantity and quick supply are as follows. (1) The houses were a prefabricated type which the residents could easily build. (2) The design could respond to the lack of material flexibly, and the choice of finishing materials depending on the local situation was possible. (3) The compact organization system could perform the stocking, manufacturing, sending, and budgeting execution of the construction.
