Nishi-Kyushu Shinkansen Nagasaki Station

Nagasaki Station has undergone a once-in-a-century transformation. With the opening of a new Shinkansen line and the elevation of the conventional local train track, the station was redeveloped to integrate the two railways into a single structure. The design of the new station aimed to be a suitable new entrance to the city, with both lines enveloped by a unifying grand roof to create a bright and open platform. It is the first instance of membrane roofing ever used on a Shinkansen platform in Japan, and its three-dimensional movement toward the sea gives the platform a sense of dynamism, making it a landmark for Nagasaki. The complex steel frame structure that supports the roof was carefully verified for volume and shape using BIM, and the curvature and composition were standardized for each component to achieve a rational structure. In the concourse, materials originated in Nagasaki, such as brick tiles, steel, and wood, were used to create a space that evokes a sense of history and culture.
