Rainbow Bridge, a symbol of Tokyo and a tourist attraction popular with many, is a suspension bridge connecting the waterfront area to Tokyo's urban center. Part of the Metropolitan Expressway No. 11 Daiba Line, it is a multimodal transportation line consisting of the harborside road and the Rinkai New Transit System (Yurikamome). Rainbow Bridge leverages the characteristics of a suspension bridge against the backdrop of the straight lines of the waterfront city, and features soft curves arranged on the vertical lines of the main towers and piers to give an impression of grace amongst sprawling comfort.

Rainbow Bridge has been illuminated since its completion in 1993, and due to the lighting fixtures aging, upgrade work was carried out in 2020 to convert the lighting equipment to LED. The upgrade work saw the existing HID floodlights replaced with LEDioc FLOOD FULL-COLOR full-color LED floodlights, which can freely express a variety of light colors highly efficient, and high-color-rendering LEDioc FLOOD ZEST LED floodlights, a change that has enabled the production of higher quality lighting effects while achieving significant power savings. In the past, changing the color involved changing the color filters, but now that is no longer necessary and the system can be operated via program control from the facility's control room, something that has enabled improved work efficiency. The main tower is usually lit up in a cool-white summer pattern (April to October) and in a warm-white winter pattern (November to March), with special lighting (rainbow colors) during the year end and new-year holidays.

In 2020, due to appeals from the Tokyo Metropolitan Government and the City of Yokohama, the main towers started to be lit up in blue from April 22 onwards as a "Medical Personnel Support Illumination" to show appreciation and support for medical personnel and others who are working hard to treat patients infected with the novel coronavirus. Following that, from May 25, in cooperation with the Tokyo Metropolitan Government's efforts, the lights were set to the Medical Personnel Support Illumination from sunset to 20:00, and from 20:00 to 24:00, depending on the status of the "Tokyo Alert", rainbow colors or red to warn people of the spread of infections. With the lifting of the Tokyo Alert on June 11, the illumination of the tower according to the alert has been temporarily suspended, but the tower has continued to be illuminated as an expression of gratitude to medical personnel and others, with the main tower illuminated in the usual white from sunset to 19:00 and in blue from 19:00 to 24:00, adding color to the night view of the Port of Tokyo.
