The Hill of Oshitoishi

Five peaks surround the Mount Aso caldera, and the meadows of one hill at an elevation of 845m is lined with several hundred rocks of all sizes, and the biggest of them all is called the "Oshitoishi."
Ancient petrographs have been discovered on a megalith near the top, and it is believed to be a place of worship for ancient maritime Sumerian people.
