The mobility of people's activities, and cloud computing technologies are becoming advanced in the modern age of information and globalization. This study describes the capability of discussing townscape design while sharing a 3-dimensional virtual space with stakeholders in a distributed and synchronized environment. First of all, a townscape design support system based on a cloud computing type VR system is constructed. Next, an experiment of a distributed and synchronized discussion of townscape design is executed with examinees who are specialists in the townscape design field. The conclusions are as follows: 1. Users who use VR frequently and who use videoconferencing consider that the difference with face-to-face discussion is small. 2. The capability of distributed and synchronized discussions in the townscape design field is high.
