Cosmo Tower (formerly known as the World Trade Centre) is western Japan’s tallest building and the second tallest in the entire country, soaring to a height of 256 metres.
The 55-storey skyscraper houses offices, restaurants, exhibition halls, a museum, and even a wedding venue. One of its standout features is the 360-degree Sky Lounge and Observatory, offering arguably the best panoramic views in Osaka.
As the tallest structure in the region, Cosmo Tower also serves a technological purpose, hosting broadcasting equipment and housing one of Osaka’s major media hubs, as well as dozens of international business offices.
The 55th-floor observatory boasts spectacular views of Kansai International Airport, Osaka Bay, Awaji Island, and even Mount Rokko in the distance. A highlight of the experience is the transparent elevator, which whisks visitors up 52 floors in just 80 seconds, rising dramatically from a waterfall and reflecting pool that stretches out to an outdoor plaza.
Constructed in an earthquake-prone country, the tower is equipped with advanced safety technology, including computerised vibration control systems, world-class smoke detection, and a green air-conditioning system designed to minimise environmental impact. The building also features state-of-the-art security and comfort systems.
Opened in 1995, Cosmo Tower embraces a cosmic theme throughout its design. The black marble foyer is adorned with abstract art representing the sun, moon, stars, and planets, and is complemented by huge stainless steel panels interpreting the celestial heavens.
The foyer floor is brought to life by a dazzling fibre optic light display—a twinkling Milky Way that adds a romantic touch, especially at twilight. It’s easy to see why Cosmo Tower is a favourite date spot for young couples and a popular venue for weddings and photo shoots.
Access is easy, with just a three-minute walk from Trade Centre Mae Station on the OTS (Osaka Technoport Seaside) Line.
