Introduction to the Rainbow Bridge: The Rainbow Bridge is a suspension bridge across the northern part of Tokyo Bay in Tokyo, the capital of Japan, connecting Shibaura and Odaiba in the port area. The Rainbow Bridge is 1,700 meters long. It is the symbol of Odaiba and the holy land of Japanese idol dramas. I don’t know how many idol dramas have used this as the background. Every evening, 444 lights will light up at the same time, reflecting each other with the sea water, adding a romantic atmosphere to couples, making it the best date place for young couples.
