The new skyscraper is owned by Japan Railway’s Kintetsu Corporation and is located near the Abenobashi Station. It will be inaugurated in March 2014.
Its name, Abeno Harukas, comes from the name of the Osaka ward Abeno-ku and from the word Harukas, which can be translated as "to brighten, to clear up" - a hint to the clear view over Osaka that will be offered by the new skyscraper...
Abeno Harukas will be 60 floors tall, with a huge observatory occupying 3 of its upper floors, with an open-air outdoor plaza at the 58th floor, a hotel (Osaka Marriot Miyako Hotel), offices and a department store. Another noticeable feature will be the art museum which will have a rooftop garden at the 16th floor.
