Tokyo Skytree

At 634 meters, it's the tallest tower in the world (second tallest structure after Burj Khalifa). Completed 2012. It's a TV broadcast tower first—the tourist stuff came after. Two decks. Tembo Deck at 350m has floor-to-ceiling windows and the main views. Tembo Galleria at 450m is a glass corridor spiraling around the tower—more vertiginous, slightly better photos. Clear days show Fuji; hazy days show smog. Check the weather before paying 2100+ yen. Tokyo Solamachi at the base has 300+ shops, restaurants, and an aquarium—plan B for clouds. The curved shape references Japanese sword blades (according to the architects). Night lighting alternates between pale blue (iki) and purple (miyabi).
