Kirosan Observatory Park

The observatory park is located at the top of Mt. Kiro at the southernmost point of Oshima Island. The view from here is known as the most spectacular on the Shimanami Kaido. On fine days the view extends as far as Mt. Ishizuchi, the highest mountain in western Japan. In the evenings, views of the sunset and the illuminated Kurushima-Kaikyo Bridge are exceptional. The observatory itself is unobtrusively located within the mountaintop and surrounded by trees to preserve the natural landscape. Along with the stunning views, the observatory is also acclaimed for its uniqueness designed by Kengo Kuma, winner of the Pritzker Architecture Prize Of architecture.
