Tokyo Skytree — 634 m, world's tallest freestanding tower. The highest public level is the 450 m Tembo Galleria — a glass tube walk with views 70–80 km on clear days. Spot Nippon Budokan and Palaceside Building near the Palace.
100 m below, the Tembo Deck (floors 350/345/340) wraps 5 m glass at 71° — double 10 mm tempered panes.
