COLLABORATIVELY UPGRADING AMENITY AND SAFETYTokyo Station Yaesu Underground Shopping Arcade | Tokyo, Japan, 2010 NSC Site Area: 7 hectares | Below Floors: 2The Yaesu side of Tokyo Station is the gateway to one of Japan’s leading business and commercial districts and has a tremendous volume of people passing through it day and night. Within this context, the Yaesu underground shopping arcade and car park, directly adjoining the station have been constructed.The origins of the underground development date back to the 1950s, at the height of economic growth, when considerable economic investment was being made to upgrade urban infrastructure such as roads and parking facilities to add vitality and to address the signicant problems of vehicular congestion and deterioration of air quality. The Yaesu underground shopping arcade (Tokyo’s largest underground mall) opened in 1969 providing a pedestrian only access route to the station separated from trafc. Almost 50 years after its opening and with signicant ageing of its physical environment and mechanical systems, it became clear that the underground shopping arcade would need comprehensive redevelopment and became a key component of an integrated redevelopment plan with the comprehensive redevelopment of the Yaesu side of the station, including new buildings and the reconguration of the roadside area and the station plaza directly above.Redevelopment of transportation infrastructure becomes challenging to align all private and public stakeholders to the same direction. In the case of Yaesu East Exit, private building owners, operators and tenants of the underground shopping arcade and underground car park were amongst the private interest groups. Modications of existing underground facilities in particular require sensitive project management by a team well-skilled across the disciplines of building engineering, public works, and urban planning regulations.Through an integrated and coherent design process and strategic phasing, NIKKEN SEKKEI URBANISMSUBTERRANEAN SPACES048 _ 049
