• When I was a student, I was wondering from Faculty of Science to Institute of Low Temperature Science via GSES in the campus of Hokkaido University. I got a job in Niigata Prefecture, and now I am in this graduate school. Meanwhile, I got Ph.D. (D.Sc., sensu strict) by research on volcanic succession that is one of the major subjects of plant community ecology.
• I have researched not only volcanic succession but also the other disturbed ecosystems, such as skislopes and post-mining areas. I enjoy the research with friends and competitors.
• After the research of the largest wetland in China, I started long-standing research on the conservation and restoration of wetlands. Based on the background, I went to long-term overseas surveys for three times (USA, Canada and Australia). The research keeps going with foreign collaborators.

• I feel "global warming" when I research volcanic succession (if you want to know this reason, please ask me directly), "environmental deterioration and rehabilitation" when I research vegetation on skislopes and post-mining areas, and "ozone layer depletion and UV" when I was in Western Australia.
• I am trying to integrate successional theories on the basis of disturbance. To figure it out, I have a plan to research disturbed areas more. Let's see such "cool" areas with me!
• My major technique to approach the goal of the study is field work. Somebody says, that means "only power, with no brain." I do not like complex technicality, or am not good at handling it.
• I am in the scientific adviser committee of Toya-Shikotsu Global GeoPark, probably because of my history.
