This book discusses the language policies in Korea under the control of Japan's imperialism. In particular, during the Pacific war period of 1937-1945, the Government-General of Korea implemented policies to impose the use of the Japanese language with nationalist and imperialist motivations. This book introduces and comprehensively studies administrative documents and articles reposited in the National Archives of Korea and published as Chosen Sotokufu no kokugo seisaku shiryo or 'Documents of national language policies by the Government-General of Korea' in 2004. Japanese Language Dissemination Policies in Colonial Korea contributes to the growing attention towards historical perceptions over Japan's colonial administration of Korea and its discussion will be significant in the comparative research of colonial language policies all around the world.
