The book features recent academic works on economic history of the city and housing, researched from an advanced perspective of comparative history in Japan. The aim of this book is to make works by Japanese scholars accessible to a wider readership throughout the world.

The first chapter analyzes the characteristics of the urbanization that occurred under the land readjustment projects implemented from the Sino-Japanese War to the reforms following World War II, by focusing on the conflict between landowners and peasants in Japan. The second chapter examines the construction of urban housing following Japans defeat in World War II, focusing on the reconstruction of war-damaged housing from the perspective of the creation and distribution of private residential space under Japans postwar regulatory regime. The third chapter examines the adoption of communal unemployment insurance systems in Wilhelmine Germany, focusing on the Genter system, in which the municipalities paid subsidies to the trade unions that provided their out-of-work members with unemployment benefits.
