Abstract
This study aims at examining the change of the urban space of the original Masan Area during the Japanese-forced colonial era of Korea(1910-1945) after circa 1912. That year is very important because the modern map of land was introduced. The land area of the original Masan was about $17,000m^2$ composed of small houses and shops. Colonial era could be divided into 3 periods according to the change of colonial policies. And the change of the urban space is examined according to these 3 periods. During the 1st period(1911-1920) the following 3 development occurred. 1. Land was reclaimed along the coast line by a Japanese civilian named 'Bakgan'. And his ownership of land continued until 1945. 2. A government ware house(Cho-Chang), which was the symbol of Masan harbor, was demolished and the land was divided into small lots. 3. Main artery and trunk roads(14-15m wide) were built replacing 2-3m wide narrow roads and connected to the reclamation land. During the 2nd period(1921-1930), also land reclamation and road making was more frequently carried out. And the infrastructure of the city was developed gradually. Also public buildings began to be built. Modern roads were constructed city-wide not only in the center of the city. In the 3rd period reclamation was at its peak. Especially Sinpo-Dong area located at the middle of New and original parts of Masan was reclaimed connecting 2 parts and making of a central Masan. During that time original Masan was enlarged because of reclamation. The coast line of Masan became straight from e original organic shape. Roads were constructed in the outskirts also. The size of land lots were more or less the same during the colonial era. But gradually lots were divided into smaller lots. Japanese entrepreneurs gradually occupied the central area of the original Masan until the liberation day. But Chinese ownership of land gradually diminished.
