Outline of Final Research Achievements	The project aims to elucidate the mechanisms of natural photosynthesis and to develop artificial photosynthetic systems using an interdisciplinary approach involving researchers of physics, chemistry, and biology, etc. The project designed and made the research policy and plans, held area meetings and open symposiums each year, supported interdisciplinary research projects within the research area and inter-changes and collaborations with those from both within and outside of the research area (including both domestic and oversea), educated and supported young researchers, spread the research achievements that the research area obtained, and issued news-letters each month. As a result, the research area achieved excellent results in deciphering the mechanisms of natural photosynthesis and development of artificial photosynthetic systems, as well as in the instrument and measuring of natural and artificial photosynthesis by using advanced experimental and theoretical approaches.
