Being Osaka's tallest building, this tower features malls, restaurants, shops and offices. Most interesting for tourists is probably the Abeno Harukas Art Museum (changing exhibitions, around ¥1300) and the observation deck Harukas 300 on 60th floor in 300 m height (¥1350). If you want to get a good view of the city for free, take elevators and escalators to 17F, then change into one of the business elevators to 30F. There are large glass windows on all sides of the building offering views onto all of Osaka for free!
