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.

Cement roof-tile in Okinawa had a great impact on the formation of the Okinawan landscape. This cement roof-tile was brought from Taiwan and produced mainly in Nago City, Okinawa, and spread widely throughout Okinawa. However, Currently, cement roof-tile is not being produced. The purpose of this study is to investigate the situation of cement roof-tile in Nago City and to clarify the vicissitudes of cement roof-tile and their uses in building components. The results of the survey showed that cement roof-tile use was on the decline. However, the survey also revealed that cement roof-tile is used in distinctive ways.

Hisao Nakaza was one of a handful of architects who contributed to building activities in Okinawa before, during, and after the Second World War. He engaged in the post-war recovery construction in the forefront immediately after the war, and later served as the first president of the Okinawa Society of Architects & Building Engineers (O.S.A.B.E.). Nakaza was a pioneer who represented Okinawan architectural society in the early post-war period. This study defines the period before 1960 as the dawn of concrete house popularization in Okinawa and aims to clarify the aspects of the development of architecture in Okinawa during this period, examining the architectural activity of Hisao Nakaza, who played a leading role in laying the foundation for the spread of concrete buildings. Results obtained from each section are as follows: 1) Nakaza was engaged in the public construction work in Okinawa before the war. That experience correlated to his active involvement of public work of American Army immediately after the war and he obtained advanced technologies. He employed masonry construction methods, utilizing local materials from 1950 to 1953 when material procurement and factory equipment were incomplete for the Reinforced-Concrete (RC) building. After 1954, he made the most of the properties of RC building, which made free form possible and also designs were changed. He was also devoted to designing activities and writing activities for magazines and newspapers and enlightened people on the dissemination of non-wooden buildings. 2) During his tenure as the President of the O.S.A.B.E., Nakaza organized discussion meetings of engineers and competitions of farm house design. Discussion meetings promoted the common consciousness of the dissemination of concrete housing among the engineers. Competitions nurtured young architects and at the same time offered the opportunities to make people known a new image of farmers' housing. Furthermore, interactions between Japanese and American engineers staying in Okinawa through meeting led to the publication of booklets about rural houses. In addition, requirements for concrete housing suitable for the land and climate were presented. Furthermore, financing facilities and tax system revisions for the establishment of concrete buildings were requested to government. 3) In the development of housing design, starting from 1949, masonry construction was performed for two years. After stone building and brick building were examined, non-wooden building was fulfilled. Concrete block (CB) building was introduced to build plumbing water parts of wooden houses around 1955, which improves durability, sanitation and handiness. CB building was frequently employed between 1952 and the beginning of 1955, which were designed by taking into consideration the climate features of the region from the beginning of the first introduction. The farmer house model of CB building was opened to the public and earned a great response. Finally, RC building entered the mainstream in 1956. At the same time, screen blocks were created and frequently utilized. The shape of screen blocks was contrived where both usability and exquisite design were found for the subtropical climate of Okinawa. As stated above, Hisao Nakaza was dedicated to the activities of the dissemination of concrete housing in diversified fields such as technical aspect (design), publicity (writing to enlighten people) finance (request for the support of financial policies) and education (cultivate architect at O.S.A.B.E). This study examined the process of Okinawan architecture after the war and revealed that the history of modernization was based on not only the unilateral receiving of advanced technology under military occupation but also the initiative struggle of the local architect, Nakaza, with roots in the region of Okinawa.
