You can't go to Tokyo without going to one of its observatories. It is worth it to do the Top Deck Tour, the view is so much nicer at 250m above ground. I enjoyed the elevator ride the most because the view is magnificent especially while the sun was setting. They do a complimentary picture which was cute and if you wanna buy a hard copy, you can do that at the lobby.
Tip: Make sure you book a reservation online because they can get busy on some days.
Better Tip: Go during sunset so you get to see the daytime and nightime view. Both are equally amazing!
