Aerial photos reveal groups of Japanese cedar trees swelling toward the sky, creating two forest circles. According to a 1973 document from the Japanese Ministry of Agriculture, Forestry, and Fisheries, researchers had embarked on a project designed to examine tree spacing and its effect on growth. According to Japan’s Ministry of Agriculture, the height difference between the smallest trees at the center and the tallest trees on the outer ring was over 5 meters. Again, this implies that trees in less dense areas have more access to resources while trees in the center, have to compete for sunlight and water. The research team is bringing the experiment to an end. The trees will be harvested unless they are preserved as a tourist attraction.
