When you are ready to take a trip up the tower, you can either get a
Reserved Ticket or a numbered ticket to line up for the Day Ticket. The price of the ticket (adults) to go up to the Tokyo Skytree Tembo observation Deck (350th floor) is
2000 yen (
2500 yen for fixed dates) and you'll need to pay another
1000 yen to go up to Skytree Tembo observation Galleria (450th floor).
Tembo observation Galleria is open from 8:00~22:00 and the detailed explanation for each floor can be found
here.
