Recently, the public comment, one of the opportunities for citizens to participate in administration, is conducted not only in central government ministries and agencies, but also in local governments in Japan. In this study, we investigated actual conditions of public comments-aided citizen participation in conservation and practical use of gardens as public properties. We searched the case of public comments which were provided more than one opinion about conservation and practical use of gardens through internet. As results, we picked out 11 cases of public comment and 36 provided comments. Examining their methods, the comments, and replies from implementing administration agencies, we found some tendencies among them as described below. The offering information and prepared means for providing comments were not enough to promote citizen participation. The comments about conservation of gardens were more than their practical use. Although various subjects of the public comments were implemented, some administration agencies seamed not so positive in implementation of them. We considered that it was desired to increase public comment procedures through ensuring more fairness and transparency, to promote garden management system depended on citizen participation.
