The conditions of the properties in Tokyo after the earthquake on March 11th, 2011
The northern Japan earthquake happened on March 11, 2011 was measured JMA seismic scale upper 5 in Tokyo area.
Although windows of some building were broken in Tokyo, none of the buildings in Tokyo collapsed.
The buildings in Japan must satisfy very strict architectural requirements set by Building Standard Acts. The structures built based on the new earthquake resistance standard after 1981 are guaranteed to tolerate any impact of JMA seismic scale 6-7 intensity. Whenever a large earthquake hits Japan, this standard has been reviewed and revised after the thorough investigations.
Our staff has investigated the conditions of some properties between March 15th and 17th. Here are the findings:
<High-rise apartment >
Park Court Toranomon Atago Tower 26F

With regard to the elevators which was raised as a concern of high-rise building from this earthquake, the elevators of Park Court Toranomon Atago Tower has an auto control system in case of earthquakes. When the auto control system activates, the elevator will head to the nearest floor, open the door and stop there automatically. The system activated at this time. Thanks to this system, no one was trapped in the elevator. In addition, the elevator recovered and started its operation 2 hours after the earthquake.

All doors including the entrance and indoor doors opened and closed smoothly. The doors of kitchen cabinets as well as storages including a walk-in closet are also attached property and there was no sign of looseness.
Though this building is 31 years old, the entire building didn’t appear to have any damage even after this earthquake. This property was designed by an architectural office after the famous architect, “Junzo Itakura”. This neighborhood is known as a historical area where feudal lords’ houses gathered during Edo era. The stability of ground also seems to warrant the safety of the property against earthquakes.
