It was going to examine it for Palau local Korean Workers forced mobilization by this report in 1943～1944 year by analyzing “a Korean Worker-related file” “A Korean Worker-related file” is a document with the data regarding the Korean workers who are mobilized in Palau area. As for this document, only a part of a document seems to have been introduced to the country mainly on a list judging from the state of binding at the time of acquisition. However, relevancy is confirmed by each list recorded by a document, and some documents are attached, and it tries to be examined various matters through this. “A Korean Worker-related file” consists of a list of workers mobilized to 1943 and 1944 greatly in a year. It is analyzed into not showing what difference even compare it with before the outbreak of Pacific War. Watch the transportation rate, a movement period of mobilization workers well in 1943. However, compare it in 1943 in the case of 1944, and transportation rate relatively falls and have a long it much more for a mobilization period and appear in what it suffered from. It is thought due to the result that mobilization workers are active in escapes as for the cause why lost transportation rate. The reason why have a long movement period was the war situation which is Japanese armed forces dealt with the defensive had an influence on the workers transportation. Firstly South Seas Government’s department of traffic engineering works section calls out workers and managed them but it is grasped in West Branches Office engineering works section having substituted for traffic region engineering works section from a point in time that there is. This middle Western Branches Office engineering works section is the post which is not confirmed in then South Seas Government. The point where there was a difference a little is confirmed between post placement in a system and real administration. Probably it is supposed in being the situation the district under the South Seas Government dealt with namely the result that appeared because it ranked as battle front of a section to US and resources of coming and going things are limited and deserved to be reality and administered post of group flexibly. In the workshop where mobilized workers were posted, only South Seas Government direct management construction. According to the survivor testimony, one of them is seen to Malakal with being a dock construction site only for Palau harbour which did material in these South Seas Government directly managed the construction spots. It seems to have been posted in public works ground throughout the Palau, but a concrete workshop is not confirmed. A name is confirmed with a civilian employee who did the register which is recognize in “Korean Worker-related file” partly. Considerably many numbers are confirmed in these by having died in Palau. Though handle it, and the workers who died since it is mobilized at the time of the Pacific Wars by war accomplishment was done by civilian employee, in such a case these are thought about. A general worker is estimated by the register of a civilian attached to the military after death having made ends meet in the point that was not included in a protection object of the armed forces.
