Miyazaki’s Forest Management Department uses drones to capture a pair of mysterious circles made of cedar trees.
The Miyazaki prefecture is known for producing Japan’s largest supply of cedar trees, and the Nichinan city’s forest is populated with Obi-sugi cedar trees.
According to prefectural officials, the mysterious cycles are actually the result of a 45-year experiment in experimental forestry, under which researchers planted cedar trees to study the effects of forest density on tree growth.
There are 12 rounds of synchronized cedar trees in the circles. The circle is now 69 meters wide (266 ft). A Japanese forest is dotted with strange circular patterns, but it isn’t necessary to speculate that they are alien artwork.
In fact, the spiral formations visible on Google Earth were the product of experiments conducted by the Japanese government more than 50 years ago.
Researchers began examining the effect of tree spacing on growth in 1973, according to a Japanese government document.
Apparently, the experimental forest near Nichinan City was designated by the project, Spoon and Tomago, as an experimental forest. In one experiment, researchers planted cedar trees spaced in ten-degree increments to eventually form ten concentric circles. There seem to have been two instances of this.
A fanning pattern can be seen from above thanks to the way the trees were planted.
The trees will be harvested in five years. Officials said they are now reconsidering the plan because of public interest.
