Sakishima Cosmo Tower Observatory さきしまコスモタワー展望台

A bayside observatory at 252 metres in the Osaka Prefectural Government Sakishima Building, with a wraparound glass deck that catches some of the best sunsets in Osaka, over the bay, the bridges and Kobe.

About

Built in 1995 as the Osaka World Trade Center, this 55-storey tower on the man-made island of Sakishima now houses prefectural offices, and its top floor is a public observatory. A long escalator rises inside a glass tube at the top before you step into the 360-degree glass gallery. Because it sits right on Osaka Bay, the views are different from Umeda and Abeno: container cranes, the Minato Bridge, Tempozans Ferris wheel, USJ, the Akashi Kaikyo Bridge in the far west and the sun setting behind the Rokko mountains. It is certified as a Japan Night View Heritage site and is a favourite date spot at sunset. It is cheaper and far less crowded than the city-centre observatories.

Highlights

• 252 m glass observatory directly on Osaka Bay
• Sunset over the bay and the Rokko mountains

Tips

• Arrive about 45 minutes before sunset to get a window spot on the west side.
• Closed on Mondays; check before going.
• Combine with Kaiyukan and Tempozan, two stops away on the Chuo Line and New Tram.
