Tokyo Skytree is now the highest tower in the world with a height of 634 meters. You can get some incredible views of Tokyo including the Sumida river region, Sensoji temple, Ueno park, Tokyo Tower, Mount Fuji and more! Sky Tree is extremely busy since its opening, get there early to minimize the wait. A 30 min wait to buy tickets is not uncommon and gets longer during the day (the ticket line extended out of the building and under the sun by noon). The second deck requires you to buy an additional ticket from the main observatory, be prepared to wait 15-30 minutes again in crowded conditions. Plan plenty of time for waiting in line because the visit is well worth it!
Restaurant-boats are a common sight along the Sumida river in the evening but can also be seen in great numbers in the bay of Tokyo.
On the menu : typical isakaya-style fare or okonomiyaki and plenty of beer. Some of them have a terrace accessible on the roof to take a breath of fresh air and enjoy the night scenery of Tokyo.
Edo Tokyo Museum is huge, and is held in the air! It was actually modeled according to an old storehouse style. The museum presents the last 400 years of history Tokyo, formerly called Edo.
