|Japan is one of the world’s most densely populated nations, with an average of 339 people per square kilometer. It is also one of the world’s most active seismic zones. More than 140,000 people died in the 1923 Great Kantō earthquake, which leveled the nation’s capitol of Tokyo. The Tōhoku earthquake and tsunami of 2011 was the world’s costliest natural disaster to date, with damages estimated at $235 billion. The combination of these factors has driven sophisticated design and engineering innovations that responded to Japan’s uniquely challenging environmental conditions, including in the tall building field, which continue to this day.|
This study is included in Issue II of the CTBUH Journal, which focuses on Japan’s latest innovations in tall buildings, from mixed-use programming, to resilient urban planning, to seismic and façade engineering, and more. The themes explored in this publication coincide with the exciting program for the inaugural CTBUH Japan Chapter Event, entitled Vertical Habitat – Vision 2020 and Beyond, to be held May 22 at Roppongi Hills, Tokyo. Speakers will include Professor Peter Rees of the Bartlett School, CTBUH Chairman David Malott, Principal at KPF, Kai-uwe Bergmann, Partner at BIG, Toru Abe, CEO and Managing Director at Sekisui House Australia, Satoshi Toyoda, Partner at Rafael Viñoly Architects, and Tomohiko Yamanashi, Principal at Nikken Sekkei. Speakers will be joined by a panel of Japan’s key decision-makers to discuss Tokyo’s plans for 2020 and beyond.
