This article analyzes Japanese emigration fishing villages in Busan area in the early 20th century. First, it is to show the types of settlements and presents the categorizations of their types of management. Most of the Japanese villages in Busan were built for three years(1906-1908) excepting Jeolyoung-Do which had been built in 1897. The types of settlements were divided into three category like Natural Emigration(Jeolyoung-Do), Assistance Emigration(Yongdang, Hadan, Dadeapho), Mixed Type of the Two. The last one started as Natural type but transformed into Assistance one. But the Japanese villages in Busan in the colonial era could be categorized on the type of management as follows. First, the type of management on a base. This type had a solid economic bases and showed the consumerism like an urban area. Deabuyn and Jeolyoung-Do were included in this type. Second the type of half peasant & half fishing. This type of villages like Youndang accommodated Japanese people emigrated through the Dongchuck. Third, the type of shipowner. This type had a special managerial structure like that the shipowner rent ships and fishing tools to fishers for appropriating certain fishes. The villages like Hadan having a tendency of business were included in this type. Second, the currents where the Japanese were from. The followings are the high rankings of region of the emigrated from first to fifth in 1921: ① Hiroshima 15.90%(734 emigrants), ② Nagasaki 13.76%(635 emigrants), ③ Yamaguchi 13.65%(630 emigrants), ④ Okayama 8.92%(412 emigrants), ⑤ Fukuoka 4.76%(220, emigrants). The ratio of these high ranking regions is 57.02%(2,631 emigrants) of total emigrants in those villages and the people from Hiroshima were far in the lead. The component of the emigrated in each villages is as follows. ① In Deabuyn, both of the people from Fukuoka and Ehime represented 34.21%. ② In Youndang, most of the villagers were from Yamaguchi(46%) and Ohita(44%). ③ In Jeolyoung-Do, the people from four regions as Hiroshima(17.27%), Nagasaki(14.59%), Yamaguchi(13.85%) and Okayama(8.21%) represented more than half, 53.92%. ④ In Hadan, the order is like this; Okayama (37.93%), Gumamoto(15.51%), Nagasaki(11.49%). ⑤ In Dadea-Po, the majorities were from Fukuoka. Third, the fishing activities of both of the local residents and the Japanese. The Korean fishermen in Busan caught herrings and cods chiefly with a gill net or an Earjeon fishery way. On the contrary, Japanese mainly fished anchovies with Jieymang and herrings with tri-angular set net or pound net. But in 1921, the main fishes in Daebuyn were Japanish spanish, see eel, mackerel; in Yongdang, anchovy, snapper, squid, perch ; in Jeolyoung-Do, twenty kinds of fishes including mackerel, Japanish spanish; In Hadan, eels and carps. The eels caught in Hadan were exported to Manju. Fourth, the relationship between the people in Busan and the emigrated. Two people not only made joint ventures like youth and adult groups or cooperatives but also fished in cooperations with each other. So Korean were not exploited or plundered unilaterally by Japanese settlers but both of them had good relationships with each other in pursuit of common interests on the ground of "reasonable contract and agreement"
