300m height is the Abeno Harukas Tower, we really enjoyed!
JPY1500 entrance to take you to the rooftop. the views are amazing on a bright day and it took us around 90mn to do the tour, enjoy a Abeno Harukas coffee and understand the different sides of the tower, a nice afternoon out.
It is super easy to reach it as it is on the loop line of Osaka, above the Tennoji station
Once there, there is hardly any queue. the elevator is designed so you enjoy the ride, you hold yourself and look up to see the floors passing by up to the 60th!
