The top floor of Sakai City Hall is open to the public as an observation lobby, making it accessible to all city residents and a friendly building. Located about 80 meters above ground, the floor has large observation windows in all directions, offering a spectacular 360-degree view. Below you can see the Sakai cityscape, including the world's largest keyhole-shaped burial mound, Emperor Nintoku's Tomb, and on a clear day, you can see Mount Ikoma and Mount Kongo to the east, Awaji Island and Mount Rokko to the west, and Abeno Harukas to the north.
