In March and April 1948 Koreans across Japan rose up in protest after the Japanese government began to enforce an order handed down to them by the American Occupation administration to close Korean ethnic schools. One such protest took place in Kobe on April 24 when Koreans stormed the Hyogo Prefecture offices in an attempt to get the governor to rescind the order to close the four Korean ethnic schools in the prefecture. American and Japanese administrations reacted harshly to the Korean actions. Police arrested thousands of Koreans and inflicted stiff penalties on the incident's leaders. As was often the case, the Occupation administration misinterpreted Korean intention to keep the schools open as a leftist attempt to disrupt U.S. occupations in Korea and Japan. Here the incident is examined through the eyes of one Occupation employee, Elizabeth Ryan, a 31-year old court reporter who included detailed information on the incident and its participants in personal letters that she sent to her family in the United States.

[12] In another undated letter Ryan writes that the massive “Korean hunt” was a demonstration to the Russians (who were suspected as “behind all this unrest”) to make them, as she put it, “stay out of our play pen here.”

He writes that although from around the time of Syngman Rhee's 1948 election southern communists began receiving guidance from North Korean communists, it “cannot be said [they] were mere creatures of Kim Il Sung” (ibid., 218).

[22] CIC Reports carried statistics that suggested these acts to have been more balanced than the information included in G-II reports, which did not list right-wing acts against left-wing groups.

Had SCAP granted Koreans the special status they demanded, they would have been eligible for special food rations and other privileges afforded peoples of United Nations states. The sheer size of the Japan-based Korean population made this option rather impractical. See Mark E. Caprio, “Resident Aliens: Forging the Political Status of Koreans in Occupied Japan.” In Mark E. Caprio and Yoneyuki Sugita, eds. Democracy in Occupied Japan: The U.S. Occupation and Japanese Politics and Society (London: Routledge, 2007), 178-199.
[29] As I describe in “Resident Aliens,” more entrepreneurial returnees were able to circumvent this restriction by exchanging money en route to Korea with Japanese returning to Japan. As we shall see below, even SCAP officials recognized this restriction as a formidable barrier to Korean repatriation.
[30] Bruce Cumings offers a more complete description of this violence. See his two-volume Origins of the Korean War (Princeton: Princeton University Press, 1981, 1990). I reflect on the effect that this violence had on Japan-based Koreans in “Resident Aliens.
