About the Pedestrian Bridge “Reimei Kobashi”
Reimei Kobashi footbridge, which connects Kachidoki Station and Harumi 3-chome in Tokyo’s waterfront district, opened to the public on March 25, 2024. This footbridge crosses the Asashio Canal to Grand Marina Tokyo with a soft arching design reminiscent of gentle waves rolling over the water's surface.
The continuous white structure of the bridge hovering above emphasizes the rhythm of the water's surface through its subtle, undulating form. The shadow cast onto the water enhances the visual effect, creating the impression of overlapping waves. Through continuous three-dimensional geometric transitions, the design creates a fluid motion that can be experienced by pedestrians crossing the bridge.
The lighting is programmed to change colors gradually depending on the season and day of the week. By changing the rhythm of the lighting program for the top and bottom of the three-dimensional rippled shape, the different color combinations are designed to create a variety of impressions. In this way, the nighttime cityscape of this newly developed area, where the number of residents is increasing, can be enjoyed daily for its momentary colorful combinations and movements.
