In the wake of the Great East Japan Earthquake, many companies are reviewing and strengthening disaster prevention measures and Business Continuity Plans (BCP). In Mitsui Fudosan's office building business, thinking about what should be done to support tenant companies' disaster prevention measures and BCP led to the decision to implement initiatives in broadly the following four aspects.
At “Mitsui's offices,” various initiatives will continue to be pursued with the mission of providing an increasingly “safe and secure” office environment.

Emergency electric power
Disaster prevention specifications are being enhanced by revising the “Office Building Design Manual” to maintain the functions and environment necessary for tenant companies' BCP and accommodating office workers in buildings. In addition to “Yokohama Mitsui Building,” which was completed in February 2012, and other newly-built buildings, upgrading of equipment will be advanced in phases at also existing buildings.
Brief outline of disaster prevention specifications enhancement
- 1.Installation of 72-hour emergency electric power generators as standard equipment
- In preparation for lifeline interruption in the event of a disaster, newly-built buildings are equipped with emergency electric power generators that can operate for 72 hours to supply electric power for elevators, restrooms, ventilation, etc.
- 2.Strengthening of measures for maintaining and early restoration of major functions
- Measures for maintaining and early restoration of the functions of elevators, restrooms, ventilation, security and other major equipment are strengthened.
- 3.Expansion of adoption of building disaster damage assessment system
- A system that conducts a primary assessment of a building structure's status of damage in about ten minutes after occurrence of an earthquake is adopted at increasingly more buildings.

Disaster relief supplies
Measures are taken so that buildings can accommodate tenant companies' office workers for a certain period in cases where the office workers have difficulty returning home in the event of a large earthquake, thereby allowing the office workers to select the safer of the options available.
Some measures for accommodating stranded commuters
- 1.Strengthening of equipping supplies in preparation for disaster
- ·Stockpiling of one day's worth of water and food for the number of people corresponding to the building's population
- ·Enriched stockpiling of portable restrooms, medical supplies, rescue equipment, etc.
- 2.Strengthening of information dissemination
- ·Organizing of TV monitors and other information dissemination tools
- ·Provision of each area's status of damage, status of restoration of public transportation and other information from the Crisis Management Center to each office building

Mitsui Fudosan has set up a “Crisis Management Center,” which serves as the disaster response control tower for the approximately 300 office buildings across Japan in the event of a large disaster, at the head office in Nihonbashi, Tokyo. The space was recently expanded to enhance and enrich crisis management functions.
Main points of enhancement of crisis management functions
- 1.Enhancement of electric power and other basic functions
- Equipped emergency electric power generators that can operate for at least 72 hours and also added a function to start up all systems with one start button.
- 2.Establishment of information and telecommunications networks via dedicated communication lines
- Formed several emergency information and telecommunications networks that are not dependent on fixed-line phones, such as a video conference system, satellite mobile phones, etc. via dedicated communication lines.
In addition, established a 24-hour 365-day system where employees take shifts going on duty in pairs so that prompt response can be made even on weekday nights and holidays.
Disaster Prevention Guidebook

Toppling and Falling
A “Disaster Prevention Guidebook” introducing Mitsui Fudosan's disaster prevention initiatives and a “Office Furniture and Fixtures Toppling and Falling Prevention Guidebook” for raising awareness among tenant companies about the importance of measures to prevent toppling and falling of furniture and fixtures were issued. While utilizing these guidebooks, disaster prevention measures will be promoted together with tenant companies.

- About the structure of coordination between the Disaster Response Headquarters set up at the Crisis Management Center and each building
- 2.Disaster prevention functions of “Mitsui's offices”
- About the disaster damage assessment system, anti-seismic performance and vibration control structure, emergency equipment and stockpile
