Pedestrian Bridge Reimei Kobashi

Reimei Kobashi is a pedestrian bridge connecting Kachidoki Station and Harumi 3-chome in Tokyo’s waterfront area. The bridge opened to the public on March 25, 2024. Crossing the Asashio Canal and leading toward Grand Marina Tokyo, the bridge adopts a soft arch form that recalls gentle waves moving across the water’s surface. The continuous white structure appears to hover above the canal, translating the rhythm of the water into a subtle undulating form. Reflections and shadows cast onto the water overlap and dissolve, evoking an image of waves washing over one another and adding a poetic layer to the urban landscape. Composed through continuous three-dimensional geometric transitions, the design conveys a single, fluid direction of movement. This spatial continuity leaves pedestrians with a strong bodily sense of motion as they cross the bridge.

Lighting Design

At night, the bridge features a lighting program with different rhythms assigned to the upper and lower parts of its three-dimensional wave-like form. The lighting changes color gradually according to the season and the day of the week. Momentary combinations of light and color enrich the nightscape of this rapidly developing residential area, offering a daily experience of subtle variation and movement within the urban environment.

About Hoshino Architects Inc.

The office brings together architects and designers with extensive international experience and pursues the creation of cities, spaces, and experiences that resonate with people. The practice examines the multiple layers of each site and extracts elements that shape the urban surface, including light, color, and landscape. Through processes of layering and abstraction, these elements express the atmosphere of the city, amplifying local history, culture, and geographical context. This approach encourages people to rediscover the unique character of their surroundings.
