The spatial background of Arirang is Kimje Mangeong plain. The folklore who lived in Kimje Mangeong plain forced to leave their homeland due to the land-grab and deceptive policy of Japanese during the colonial period. They dispersed to Manchuria, Maritime Province in Russia, Hawaii and other regions. The people who migrated in Manchuria and Maritime Province in Russia, cultivated rice with the memory and experience of their rice-producing at homeland, and finally settled down the societies of China or Russia. The others who went down the sugarcane farm in Hawaii settled down in American society with the persistent and hard-working disposition learned through their experience. But many young adults and women who were drafted as military service or comfort women almost died or were missing. If they were not mentioned in Arirang, they might be forgot without knowing their names, such as Ji Man-bog, Park Yong-hwa, and Boksili. Many individuals who participated the anti-Japanese movements and struggles for independence, like Sin Chae-ho, Na Cheol, Hong Beom-do, Kim Jao-jin, Park Yeong-man, Kim Won-bong and others, could be an objective of collective memory with the help of active involvements and sacrifices of the ordinary people, like Song Su-geon, Bang Dae-geon, Bang Young-geon, Lee Gaong-min.
