Research Interests Urban Sociology & Community and Regional Studies. Both are sociological methods of study on urban societies. As you know the former is influenced by Chicago sociology. The latter has developed peculiar in Japan but it is similar to New Urban Sociology in Europe. Originally its aim was study on Japanese rural society in connection with policies and capitalism in 1940s or more early time. Community structure and its transformation by research that focus on the relations of organizational entities such as voluntary associations, not-for-profit organizations, neighborhood associations, local and other governments, companies and political groups. I am member of the research group formed by professors who are interested in NPO from sociology, theory of organization and study of cooperative. We plan to have researches on NPO in Japan, China, Italy, UK and US. Comparative study of Meals on Wheels in Japan, Australia and US. I've researched on Meals on Wheel in Japan and South Australia while I've been committee member of MOW Japan Association. I just started collaboration on MOW in Japan and US with an American professor. Acknowledgements I stayed in Adelaide, South Australia, from September 2001 to June 2002 as visiting professor at Department of Sociology of Flinders University while I was involved in a branch of Meals on Wheels South Australia Incorporated. I greatly appreciate many kindness and all help I received from all.
