This study evaluates, from a neo-Malthusian perspective, Japan’s current status and its prognosis in the context of the country’s economic vulnerabilities. Drawing on the theoretical contributions of Malthus, N. Georgescu-Roegen, H. and M. Sprout, and assorted environmental-ecological doomsayers, the author reaches pessimistic conclusions about Japan’s very long term prospects, but holds out some slim hope for Japan if international cooperation of nearly Utopian dimensions can be achieved.
