Check out the Mori Art Museum or head to the top of the Mori building for a nice view of the city. Similarly good views can be found at the Tokyo Metropolitan Government building for free.
It is 1 of the best examples of a city within the city. Opened in 2003 in Tokyo's Roppongi area, the building complex features offices, apts, shops, restaurants, hotels, museum, observationdeck & more
Take the lift on the third floor to get to the top and enjoy the amazing view. They will offer you a free photo with a trick, but of course that's not for free
the winter illumination on the main street is nice, but it is super crowded and busy with people everywhere, and the road is also always busy with cars. https://t.co/SLxRjxD1oq
Roppongi Hills has a nice shopping mall, restaurantsmuseum, planetarium and the 54 story Mori Tower. It is about a 5 minute walk from Roppongi Metro station.
This building is huge. You could definitely spend more than a few full days exploring it and still not see everything. Can't wait to spend more time here.
