Abstract
This study was aimed to find the effective way to transform people’s water use behavior into water saving one and become established in the long run. For that, we examined the continuous feedback of the water consumption of one’s own by comparing with others, who were similar in the level of living, who were similar in the family structure, and who were living in the same area. There was no difference among the way of feedback and control group. From the questionnaire survey, those who got the feedback were tended to feel that their way of water use were changed and that the interest to water were increased.
