At the present time, Japan faces many problems related to crowding or high density; shortage of housing, limited space, traffic jams, and urban problems. However, a number of scholars working in different fields have suggested that the Japanese tolerate high density because they have developed coping strategies to deal with crowding. This paper will review these strategies and relate them to the multidensity model of crowding (Paulus, 1980). This model will be used to analyze Japanese adjustment to high density. It is concluded that the Japanese view crowding as a negative experience. The increasingly high levels of density and recent cultural or social changes have inhibited the effectiveness of various coping strategies. There is a need for definitive research on the extent to which the Japanese experience a variety of negative consequences due to crowding.
