Reimei Kobashi, a pedestrian bridge located in Chuo-ku, Tokyo, has been awarded Winner in the “ARCHITECTURAL DESIGN Infrastructure” category at the Architecture MasterPrize 2025, an international award recognizing excellence in architectural design. Hoshino Architects Inc. served as the Master Design Architect for the project.
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 of the bridge, cast onto the water's surface, enhances the imagination even more with a congregation of waves seeming to wash over one another.
The design, presenting one fluid motion from three-dimensional geometric changes, provides pedestrians walking across with that feel of movement.
Design
The lighting is programmed to change colours 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 colour combinations are designed to create a variety of impressions. In this way, the nightscope of this newly developed area, where the number of residents is increasing, can be enjoyed daily for its momentary colourful combinations and movements.
