This paper discusses whether the increased entry of women, particularly married women, into Japan's labor market challenges the conventional way of assigning class positions to women by simply deriving them from their husbands' class positions. An examination of class distributions suggests that the pictures of macro-class structure provided by the conventional approach and the dominance approach show very little difference. Women, even among those working on a full-time basis, perceive their position in the stratification system using not only their own work, but also their husbands'. In contrast, men's perception is determined by their own education and employment, not by their wives'. This asymmetry in the effect of the husband's class and of the wife's class on class identification is related not only to gender inequality within the labor market but also to the division of labor by gender within the household.
