This paper shows our analysis of comparison of unemployment & unstable employment indicators (called "UUEI" hereinafter) in Great Britain and Japan, using micro-data of Great Britain for the period from 1991 to 2002. We investigated and examined the basic framework of relevant indicators and the comparability of the indicators, and carried out a comparative analysis of UUEI in both countries, based on the framework of the study of visible unemployment indicators, invisible unemployment indicators and unstable employment indicators in Japan. Contrasting aspects exist in UUEI between both countries, partly because of the difference in the conditions in the period of comparison between both countries. The employment structure of Japan is in the process of changing to that of the USA and Europe. However, the gap between the sexes has remained a major factor for the backwardness of the unemployment & unstable employment structure in Japan such as invisibility of unemployment, the high weight of discouraged female workers, etc
