Several places in Tokyo offer nice panoramic views of the city like Tokyo Skytree, Tokyo Tower, Roppongi Hills, etc. But there’s no need to line up into those buildings to enjoy a nice scenery of Tokyo. The north-western coast of Odaiba island offers a fantastic viewpoint on the bay of Tokyo as well as the iconic rainbow bridge.
Some of those photos were taken simply from the park along the coast, most of the night panorama of the bay and rainbow bridge was taken from the terrace at one of the many restaurants in the Aqua City shopping mall. Some of those are affordable and the view of the sun setting over Tokyo is priceless!
