Abstract
In addition to expansion of waste recycling efforts alone, even further reduction of waste is required if a society that can boast an environmentally sound material cycle is to be finally achieved. In light of such a requirement, most local governments have begun “Awareness Raising Programs,” whereby they strongly appeal to residents, who discharge wast, for greater reduction and recycling of waste. The effectiveness of these programs are typically based on the distribution of information in the form of pamphlets and other educational materials. Local governments make good use of media, and develop strategies that back up their policies for greater understanding and efforts by residents. In order to better calculate the impact such approaches have on the actual amounts of waste from ordinary households, we have carefully examined the quantity of household waste and performed experiments on strategies taken up by local governments. In our results, we were able to confirm that the quantity of various component parts of waste has been reduced when local waste reduction campaigns are established and information is provided to citizens who are discharging waste. These impacts continued for more than four months and the reduction of waste generation has also endured.

Key words: household waste, survey of actual waste discharge conditions, experiment planning, information distribution, waste reduction impact
