Abstract
In 1973, I visited South America, Peru and Bolivia for the first time as a free lance photographer. Thereafter I have reported nature in the Andes and Amazon source region and information about the local races and ruins every year. In this series, I introduce the plants deeply associated with human beings since ancient times and their utility including type of cultivation and wild seeds. The Inca people discovered many plants, developed them, studied them, and discovered how to make the best use of them. The tradition has been passed on to the current people. I researched the power that Incan civilization had and the power that supported the people living in the Andes, through nature and human coexistence.
