I worked to Himeji Institute of Technology (Present : Hyougo prefectural university),and Hyougo prefectural Awaji Landscape and Horticulture Academy. And now, I works for The University of Chiba Department of Gardening in 2005. I am major in the green tract of land welfare study and the man plant, and environmental health study.
