The battles of the Pacific War formally ended between mid-August and early September, 1945. However, the declarations of peace and surrender ceremonies that occurred during this time did not end informal battles across the Asian continent. Renegade Japanese military personnel refused to lay down their arms and repatriate quietly to their country. Some combed the waters between Japan and Korea in search of returnees attempting to repatriate with financial and material means in excess of that which the United States military governments allowed. Others sought to disrupt the occupation process by patrolling the streets of Korean cities and engaging in illegal and often violent activities. Koreans also caused problems by joining the Japanese in their postwar adventures or by harassing Japanese preparing to return to Japan and the Korean sympathizers who attempted to help them. Reportage of such actions appeared in the G-2 Periodic Report, which kept a daily record of such actions. These documents today open windows into the chaotic situation that the postwar era brought to Japanese and Koreans. Primarily through these reports, this paper sees the postwar belligerence that continued beyond official declarations of cease fire and peace in 1945 as kindling that sparked the broader conflicts of the late 1940s, and evolved to all-out war from the summer of 1950.
