The magnitude 9.0 earthquake and the tsunami that was triggered with waves of up to 40 m in height showed the vulnerability of urban settlements, and the necessity for cities to invest in their resiliency.COLUMN104 _ 105COLUMNNIKKEN SEKKEI URBANISMUrban or city resiliency has become a hot topic for cities around the world. Resilience can be defined as the “capacity of individuals, communities, institutions, businesses, and systems within a city to survive, adapt, and grow, no matter what kinds of chronic stresses and acute shocks they experience.” (http://www.100resilientcities.org)In 2012 Hurricane Sandy taught New York a painful lesson on its vulnerability to natural disasters, leading to the establishment of the Ofce of Recovery and Resiliency in 2014. The “100 Resilient Cities” network pioneered by the Rockefeller Foundation is seeking to help cities around the world to become more resilient to the physical, social and economic challenges that are a growing part of the 21st century.The 2011 Japan Earthquake and Hurricane Sandy also showed that vulnerability to natural disasters is not limited to developing countries, but also a topic in the world’s leading economic centers. Japan as a country with historically high exposure to natural disasters, both occasional like earthquakes and volcanic eruptions, as well as seasonal typhoons and heat waves, is promoting the definition of resiliency plans on both national and prefectural or municipal level. The following three essays showcase how Nikken Sekkei is helping cities, citizens and businesses to become more resilient. The first provides an overview of resiliency and Japanese cities, the second article explores subterranean spaces. Lastly, the case study of ‘NIGECHIZU’ explains one of Nikken Sekkei’s activities after the 2011 earthquake and tsunami.TOWARD CITY SAFETY In pace with economic development, urban functions and population are concentrated in the urban cores of Japanese cities. As individual buildings are upgraded and multi-site projects are developed, the city center becomes dense with high-capacity, multi-function architecture. But in many cases, city centers include districts left behind by this process, occupied by buildings
