One of the best observation deck in Tokyo!
From the deck, you could see a 360 view of Tokyo with no obstacles. Including most of the landmark like the Tokyo Sky-tree, Tokyo Tower and even Mount Fuji when the weather is nice. For me the best visiting time was 1 hour before sunset, which you could see the change of view from day light Tokyo to night life Tokyo. When the weather is nice, you could even see the afterglow above Mount Fuji.
Also, a photo booth was provided on the deck, photo shooting with the deck’s photographer is free but purchasing the photo back isn’t. You could choose not to purchase but I think it’s still at a reasonable price.
At last, strongly recommend to make your reservation before your visit as the deck was extremely popular especially in nice weather days. Also, prepare your wind-resistance gears before entering the deck especially in winter. Although the deck has an almost 3 meter glass curtain wall, but it’s still extremely windy up there.
