Osaka Prefectural Government Sakishima Building

The Osaka Prefectural Government Sakishima Building (大阪府咲洲庁舎, Ōsaka fu Sakishima chōsha^?), or Cosmo Tower (コスモタワー, Kosumo Tawā^?), is the second tallest building in Osaka, and the third-tallest building in Japan. The former name is Osaka World Trade Center Building (大阪ワールドトレードセンタービルディング, Ōsaka Wārudo Torēdo Sentā Birudingu^?), or WTC Cosmo Tower (WTCコスモタワー, Daburyūtīshī Kosumo Tawā^?) until June, 2010. It is the same height as the Rinku Gate Tower Building in Rinku Town, located in Nanko Cosmo Square near the Osaka harbor, Suminoe-ku, Osaka.

The 52 story building rises 256 m (840 ft) and is topped by a skylobby. It contains three basement floors, a museum, restaurants, observation deck, office space and a conference room. The observation deck is in an inverted pyramid at the top of the structure. A transparent elevator can take passengers from ground level to the top in just 80 seconds.
