Sakishima Government Building Observatory
Discover Breathtaking Views of Osaka Bay
Visit the 'Sakishima Cosmo Tower Observatory,' a landmark in the Osaka Bay area, towering in the heart of Sakishima. From the panoramic top floor (55th floor) observatory, you can see the Osaka Bay coast, Awaji Island, Akashi Kaikyo Bridge, and Kansai International Airport at a glance.
From the observation deck, you can experience inspiring views as if looking down from the heavens. Visit with your loved ones and create unforgettable memories as you overlook the breathtaking 360-degree views of Osaka.
Taller Than Tokyo Tower

Sakishima Cosmo Tower is the fourth tallest skyscraper in Japan. Therefore, the height of the observatory on the 55th floor is a whopping 252 meters. What's especially great is that there aren't many tall buildings around, so you can get an even better view of the fantastic scenery.
Amazing See-Through Elevator

The elevator that takes you up to the Sakishima Cosmo Tower Observatory is see-through, so you can see outside. So you can feel the feeling of going up over 250m and feel the excitement together.
Panoramic Night View of the Bay Area

After the sun sets, a sea of lights unfolds! You can see the night view of Osaka city along with Osaka Bay, and you can see the lights of Tempozan Ferris Wheel and USJ, and the lights of Kobe city and Akashi Kaikyo Bridge shining across the sea.
