Tokyo subways: a public-private tool to renovate the 21st century metropolis congested spaces

Abstract : This article is focusing on the Tokyo mass-transit subways congested space, in particular on its underground layer we consider as an innovative space generator. Traditionally unbalanced in terms of economic or risk issues, the eastern and western parts of the capital city of Japan are also unequal in terms of transportation service. Looking on the latest public and private subway lines’ agenda—the Ōedo line and the Fukutoshin line, which opened respectively in 2000 and 2008—brings an opportunity to recall the delayed development history of subways in Tokyo, and the early 21st century new opportunities for public and private stakeholders. While pre-existing subway stations introduced a generic system, both new ones were planned and conceived to respond to multiple purposes and scales issues. Urban regeneration dynamism, attractiveness reinforcement, natural disasters countermeasures, metropolitan accessibility, for instance, were combined with the infrastructures deep location problematic condition. Independent architects have been unusually called to solve those complex issues with simple or spectacular but adapted spatial devices including open space bonus requests. Those “privately owned public spaces” nonetheless show a risk for public urban authorities to rely exclusively on the private sector to improve the quality of collective spaces. If each new line’s specific architectural characteristics are reinforcing the historical east-west disparity of Tokyo, each one is nonetheless fitting and reinforcing the singular urban identity they are serving.
