My areas of expertise are public policy and the philosophy of science. I am particularly interested in building a bridge between the “exploration of humans” and a “vision of society”. With this in mind, there are three major foci to my research. The first includes social policies in health care, welfare, and social security, which have expanded to encompass the environment, city planning, and the revitalization of local towns. The second is philosophical explorations on death and life, time, care, and communities. The third connects the first two, and what can be called a vision of a “steady-state society” or a “sustainable welfare society”. I am currently working on a project called “Chinju-no-Mori (groves surrounding village shrines): A Vision of a Natural Energy Community”.
