During the first plague epidemic in Manchuria (1910-1911), Japanese Government-General in Korea had not reported a plague patient at all in official. This did not mean the preventive measure of colonial authorities was successful. Their prevention program and measure were operated inadequately. ⋯ They pointed out Chinese coolie as a source of infection. Though they did not know exact information and analysis on pneumonic plague, the preventive measure of the second plague in Manchuria was successful due to the well-equipped disinfection system such as house-to-house inspection and nationwide quarantine made by cholera prevention. While the first prevention of plague in Manchuria was successful despite rubbish preventive system, the second prevention of plague in Manchuria was successful due to the well-equipped disinfection system in spite of occurring plague patients.
