Safe and stable lifelines ensured

Underneath the Waterfront City, there runs a high-spec multi-purpose underground duct measuring 16 kilometers in overall length, utilizing the underground space beneath roads and parks. This underground multi-purpose duct, which can withstand an earthquake of magnitude 8 ― the same as that of the Great Kanto Earthquake in 1923 ― houses all necessary features of urban infrastructure, such as waterworks and sewerage, electric power cables, gas pipes, and telecommunications and information cables.
The underground multi-purpose duct, which is the largest of its kind in the world, is managed around the clock to ensure reliable lifelines for Tokyo's citizenry.

In the Waterfront City, all lifelines, including electricity, are based on a two-line system,
so the backup setup in the event of emergency is perfect.
The Waterfront City, which has safe, stable lifelines, meets the conditions of a business base of the future.

Developing a town highly resistant to disasters

The optimum disaster prevention measures conceivable are being taken at Waterfront City.

Such structures as bridge girders for Yurikamome and other public facilities can withstand an earthquake comparable to the Great Kanto Earthquake in 1923. Moreover, there is no need to fear liquefaction of the ground, often feared about reclaimed ground, because ground improvement measures have been taken. Parks and open spaces, which are built as areas of repose, are barrier-free so that they can offer shelters to all citizens in the event of a disaster. Sufficient measures have also been taken to protect the area from a high tide by constructing a breakwater, taking precautions against a typhoon like the Ise Bay Typhoon (Typhoon No. 15 of 1959).

"Ariake-no-Oka hill" in the Ariake Minami District is a rear support base for the defense of the entire Tokyo metropolitan area from disasters. There, a heliport and a general hospital is located.
