The use of city development workshops continues to increase, reflecting the need for citizen participation in city development legislation. City development workshops are carried out over weekly or monthly periods: continuous workshops. Even though participants may have opinions or thoughts about such discussions during or after the workshops, reflecting on them during workshop discussions is difficult. In our work, we propose a method that conduct virtual-world workshops using COLLAGREE during and after continuous real-world workshops on city development. We verified our proposed method's effects by social experiments in which continuous workshops were conducted by landowners, residents, and students. We analyzed the discussion data of both real-world and virtual-world workshops and gave questionnaire surveys to our participants. As a result, when discussion using many characters was conducted in a virtual-world workshop and participants viewed it, its contents influenced subsequent discussions. Moreover, we found that our proposed method had a psychological effect on discussions while improving.
