Since 1957, the author has studied the chemistry and biochemistry of "so called green odor" by a multidisciplinary approach involving synthetic chemistry, natural product chemistry, flavor chemistry, plant biochemical physiology, and molecular biology1～6). After 1985, the emphasis was on the relationships between the chemical structure and human characteristic response to this green odor7～12). From 1994, this was ex- tended to the theme "Why people are refreshed by the fresh green odor emitted by green leaves in forest!" To demonstrate under corroboration some effects on stress and of schizophrenic tendencies, research commenced on the effects of green odor on human olfactory receptor neurons and mechanisms of activation of smell sense organs and the impact on immunity. Approaching the 21st century, to further this work, a research project was organized by myself with an interdisciplinary approach combining life science, medicine and aromacology13～20). Under the auspices of this project, the 1st symposium on "Why people are refreshed by the fresh green odor emitted by green leaves in the forest!" was held at the Department of Pharmacology, University of Tokyo on December 6th, 1997 under support by the NISSAN SCIENCE FOUNDATION26). Subsequently, the 2nd symposium was held in 199827), the 3rd 199928), the 4th in 200029), 5th, 200130), 6th, 200231), 7th, 200332), 8th, 200433) and then 9th, 2005 in the same place, on the first Saturday of December, every year.
