Abstract
The existence of “silent group” who do not reply to surveys and/or who would not express their opinions has become big issue in planning fields. In this research, authors analyzed the consciousness of residents who would not express their opinions to the micro-area transportation planning that has been developed in Yanaka area in Tokyo. In conclusion, they found that the silent group has not necessarily accepted the proposed plan. Residents' awareness was found to be limited to the problems occurring in their extremely small neighborhood. It was also found that the response rate to surveys was heavily influenced by this fact.
