In the economic growth theory, most of the researchers interests moved from the exogenous to the endogenous factor. In the urban growth theory, the concern also gathered for the endogenous growth factor, especially economics of agglomeration. However we wonder whether only the economics of agglomeration will explain Japans urban growth or not. We examine which of the factors explain urban growth in Japan, economies of agglomeration or exogenous technical progress, extending the model of Ciccone and Hall (1996). Our results show the tendency that the city which has strong economies of agglomeration has small exogenous technical progress; on the other hand the city which has strong exogenous technical progress has small economies of agglomeration. Our results also indicate that the city which has much stronger economies of agglomeration has exogenous technical degeneration, but the stronger the economies of agglomeration become, the smaller the exogenous technical progress becomes.
