Abstract
In Europe and the United States, Open Government is executing by the three principles of transparency, public participation, and collaboration. In Japan, Only transparency, i.e.; Government data opened to the private sector (open data) is established at several central and local Governments.
Collaboration can create big innovative governments in the three principles. In the United States, etc., Open 311, which is the Internet communication tool for issues that the concern public space and services, is instead by the non-emergency phone call 311 systems, and Citizens can take that data, develop, and provide application used to that data. I consider the possibility of collaboration in Japan and the experiment in Chiba City.
