Standing 300 meters tall, Abeno Harukas (あべのハルカス) in Osaka is the tallest skyscraper in Japan. The building stands on top of the Kintetsu Osaka Abenobashi Station and is conveniently located across from JR Tennoji Station. It houses a department store, an art museum, a hotel and an observation deck.
The observation deck is called "Harukas 300" and occupies the building's top three floors (floors 58 to 60). The observation deck is accessed by elevators from the 16th floor. With large floor-to-ceiling glass panels all around, the 60th floor offers 360-degree views of Osaka, while the 58th floor features an attractively designed inner court with a wooden deck and cafe. A souvenir shop and restrooms with views are also available.
