This study examined the establishment of Japanese migrant fishing villages in Tongyeong during the Japanese colonial period and the formation of Okayama villages in Tongyeong in order to clarify the economic situation and relationship through ethnic fishing activities. In addition, in order to analyze the fishing industry by dividing it into the primary industry (fishing) and the secondary industry (fishing companies, manufacturing factories), we tried to secure each data to reveal the economy of each ethnic group. I tried to confirm what kind of stance, such as response or cooperation, was expressed in the activity.
Through this study, (1) Okayama Village, which was built in Tongyeong-gun in 1908 under the leadership of Okayama Prefecture among the Japanese migrant fishing villages, was one of the best examples of 'Assistant Migrant Fishing Village' and confirmed that the fishing activities were carried out well. (2) The biggest cause of Japanese settlement in Tongyeong was the local environment with good fishing grounds and harbors. As a result, the proportion of fishery workers among various industries was high. However, when comparing the fishing industry with the fishing industry by ethnic group, the total number of Korean fishing workers was three times higher than that of Japanese workers, but the fishing industry also found that the fishing industry had only one-seven businesses and one-tenth of the capital. (3) As such, Koreans were inferior to migrant Japanese in fishing, economic status, and capital, but when the Hiroshima On-Mang Fishing Association, which consists of only Japanese, took up most of the fishing rights, they actively moved to hold fishermen's competitions and to protect their interests.
In short, Tongyeong was one of the areas where group migration and settlement of Japanese people actively took place as it has a natural fishing port. Accordingly, most of the Japanese who migrated were engaged in fishing, and the Koreans were being pushed out of the primary and secondary industries. Nevertheless, it is noteworthy that the Tongyeong residents made an active move to keep their interests at a minimum in the unfair situation of the Japanese fishing associations taking over the fishing rights.
