What is considered important in the industrial countries is the environmentally responsible behavior as called for at the Earth Summit held in Rio de Janeiro in 1992. The purpose of this study is to analyze the relationship between the environmentally responsible consumer behavior and the time use on an individual level. Different types of questionnaire on time use were answered by 136 Japanese couples in Setagaya, Tokyo, in 1995, and the data were analyzed from the perspectives of gender and employment type. The main questionnaire contained 28 items pertaining to the environmentally responsible consumer behavior. The results were as follows : 1) Few people were involved in the social/consumer activities in the framework of social/cultural activities time. 2) The household and family-care time showed a correlation to the environmentally responsible consumer behavior. 3) Wives scored higher than husbands in the area of environmental responsibility. 4) The husbands with full-time employed wives were more environmentally conscious than those with part-time employed and unemployed wives.
