I recommend going to an extremely enjoying spot, located in Tokyo: Odaiba. Here you can enjoy a beautiful night view, with a romantic cityscape, including the Rainbow Bridge and the Ferris Wheel. In Odaiba, there are plenty of shopping facilities, and there is also a little amusement park with various attractions. Here you can find the headquarters of the famous Japanese TV channel "Fuji TV". For those who seek to relax, there is also a hot spring theme park called Oedo Onsen. For those who seek wonder, I recommend to visit Teamlab Borderless: you can navigate the confluence of art, science, technology, and the natural world through amazing digital art and not only. In conclusion, in Odaiba one has plenty of fun things to try out and places to walk around!
