You can see the building in the distance and know there is an underground tunnel from the Grand Osaka location to the Sky Building, but if you're looking the other way you might miss it. So if you're coming from the Intercontinental...when you come to the end of that building on the first floor (heading towards Osaka station)...look to your left outside of the building and across the street...pay attention to where everyone is walking and you will see them disappear on the other side of the street! Once you get to the building, its an easy ride to the 39 and then 40th floor for a great view on a clear day. If you're a single person with a love one you'll like it even more as you can confirm your love with a locket!! It was worth it, the kids liked running around on the 39th floor, but were a bit hesitant on the 40th - open air, but it was fine and safe. On the way back down be sure to take the escalator from the main building to the 2nd building for additional fun.
