This paper examines regional characteristics affecting the latent entrepreneurship in Japan, focusing on regional macroeconomic indicators, existing density of establishments and human capital, and business start-up assistance programs by local governments. We define two types of people having the latent entrepreneurship as follows (1) persons merely wishing to be a self-employed worker, and (2) persons preparing to be a self-employed worker out of the former definition. Total cash earnings and the unemployment rate, which are the macro economic indicators, had positive effects on latent entrepreneurship in Japan. Judging from the significance of their estimations, the latent entrepreneurship is explained by the "Push hypothesis". If we examine the problem more closely, it is necessary for us to identify government assistance programs which make the latent entrepreneurs more self-employment.
