Even though many studies on Environmental Kuznets curve (EKC), are following a seminal work by Grossman and Krueger (1991), limited studies are available for municipal solid waste’s cases (WKC). Mazzanti and Montini eds. (2009) is a first comprehensive study of WKC with European data. More importantly, they define a absolute decoupling as ‘descending side of an inverted U shape’ and relative decoupling as ‘ascending path of an inverted U shape. In this paper, we add a new evidence for WKC by using municipal solid waste’s data in Japan. The successful result was derived due to highly disaggregated data as was suggested by Mazzanti and Zoboli (2009) as well as the richness of data set.
