I'm sure this isn't allowed anymore, but when I went to Tokyo over 10 years ago, me and my friend were just wandering around aimlessly. On a whim we decided to find the tallest building we could and go to the very top floor to see what the city looked like. So, we spotted the tallest tower near us (a totally random and generic office tower), got into the building, and took the elevator to the very top floor to peer out a window. I still remember what the view was like. It was an endless city as far as I could see.
