In the deprived urban area it has been stressed to establish community base facility to regenerate the area and residents’ continuous participation from the planning stage is necessary for autonomous regeneration of the local community. This is an essential factor to develop the local asset that is suitable for the local community. In the past residents’ participation used to be perceived negatively as an obstacle in implementing the project of local administration. However, as the policy of government has been changed, urban development is required to be directed toward regeneration of the existing urban communities especially toward an autonomous recovery. This study describes the effect and outcome of residents’ participation in the process of planning the community base facility for urban regeneration. Participation was expected to support to improve the initial plan that was adopted in open competition. The method of this study used workshops for residents’ group that represent the local community. Workshops were accomplished in three stages according to types of plans that are the subject of debate. The workshops were carried out from March until June, 2013. In order to facilitate the communication with the residents, scaled models, floor planes and perspective images were used. As results, original competition plan was changed reflecting large portion of residents’ opinions. Participating residents enhanced their understanding about the facility spaces, improved their ability to agree with adjustment among the participating residents and reinforced their ability to consider their community and the diverse positions of the residents. The relationship between the residents and the local administration that used to be superficial and unreliable developed to a cooperative relationship that understand each other and adjust each other. In short, residents’ participation in the process of urban regeneration is not an obstacle but can be directed toward facilitation of administration tasks and decreasing the conflicts, thus evolving as an asset suitable for the needs of the local community. In conclusion, this study suggests the followings for urban regeneration: First, if residents’ group is trusted, administration works can be facilitated very much. Therefore, local administration should cooperate in carrying out the roles of residents’ group in order to help them obtain the reliability and representing function of their local community. Second, local administration should make efforts to change the relationship to mutual cooperative relationship with the residents. Earnest effort for this purpose not only facilitates the administrative works but also help the local administration carry out its tasks more faithfully. Third, in order to improve the relationship between the private and local administration it is important to make changes in the ways of thinking and behaviors of local administration and residents’ ability to reasonably communicate with their local community should be improved. For this purpose diverse programs to reinforce the residents’ abilities should be supported to put into practice. Fourth, among the diverse types of residents’ participation, use of residents’ representative group is very effective because it avoids conflictions and decreases energy consumption without the necessity of dealing with many residents.
