Two peculiar tree 'crop circles' have been spotted in Japan's Miyazaki Prefecture.
Viewable only from above, they were formed by sugi (Japanese Cedar) trees.

According to documentation obtained from Japan's Ministry of Agriculture, Forestry and Fisheries: In 1973 an area of land near Nichinan City was designated as "experimental forestry" and one of the experiments was to try and measure the effect of tree spacing on growth. The experiment was carried out by planting trees in 10 degree radial increments forming 10 concentric circles of varying diameters.

Part of what makes the crop circles so alluring are their concave shape, which was an unexpected result of the experiment that woud suggest that

Tree density does indeed affect growth.

The trees are fue to be harvested in about 5 years, but officials are now considering preserving the crop circles
