Risky cities: Tokyo

The Tokyo-Yokohama metropolis is one of the most densely populated regions in the world. It's also one of the most earthquake threatened in our rankings. Our Risky cities fact sheet on the area shows why urban resilience isn't just a concept: it's a way of life.

The 2011 Tokohu earthquake and tsunami devastated a coastal region caused 20,000 people to lose their lives.  And made the area's natural disaster exposure painfully clear: the quake and tsunami occurred only around 400 kilometers away from the Tokyo-Yokohama region, home of over 30 million people, making one of the most densely populated regions in the world.

It is also the most earthquake-threatened in Swiss Re's Mind the risk, a global survey of cities under threat from natural disasters. In addition, the Tokyo-Yokohama region is on the coast and close to waterways, which means the area is also exposed to river flood. If an event comparable to Tokuhu were to happen closer to Tokyo-Yokohama, the results could be devastating.

In Risky cities: Tokyo (PDF, 806 KB), we show the possible impacts of a natural disaster, including the value of working days lost in absolute terms an in relation to the national economy. But most importantly, we show the human impact - how many millions of people could be affected.
