This is a 153-meter-tall tower, modeled after a lighthouse. The glass-covered observatory offers you a magnificent 360° panoramic view of the Kanmon Strait, the Seto Inland Sea, and even mountains on Kyushu. You can enjoy various views in various periods of time: for example, the water surface brilliantly reflecting sunlight in the day, or nearby buildings brightly illuminated at night. The colors of illumination change according to the day or season.
