We conducted two social surveys in Gifu city, Gifu Prefecture and Imizu city, Toyama Prefecture to assess the attitudes and perceptions of non-Muslim Japanese citizens toward Islam and Muslims within their local communities. Then we published research papers and made academic presentations according to the analysis of the results of these surveys. We also held the second, third and fourth "Meeting of Representatives of Masjids in Japan" in 2010, 2011 and 2012.These are important activities for formation of mutual relationships between Muslim communities and Japanese communities.
