Take in the impressive scenery of the Oshima Straight from atop the Kochiyama Observatory, a place that visitors must go to on a sunny day in Setouchi. Koniya is visible on the left-hand side, and the jagged edge of Kakeromajima seems to go on for ages. On exceptionally clear days Tokunoshima, another island in the Amami Archipelago, can be spotted from here! The observatory is a short walk up a path from the parking lot, where restrooms and another observation deck are located. Take caution not to run into any Habu snakes on the way!
