Framework of Anti-Disaster Measures
and Anti-Disaster System
In addition to basic policies and action guidelines for natural disaster and other crisis management, the Mitsubishi Estate Group has established the Emergency Response Manual setting out the details of action in an emergency. Mitsubishi Estate also has its own Framework of Anti-Disaster Measures to ensure that necessary countermeasures are taken to protect human life and infrastructure from disasters and to take appropriate and prompt recovery measures. This framework covers a wide range of measures in a detailed manner, including standard precautionary measures, assignment of responsibilities, plans for drills, plans for emergency measures in the event of a disaster, and recovery measures. The Anti-Disaster System is put into action when a large-scale disaster occurs or is expected to occur. The Disaster Management Headquarters is established, and the company will work with government officials, police, fire department, general contractors, sub-contractors, the Chiyoda Medical Association, and St. Luke's MediLocus to support stranded commuters, respond to the injured, and conduct emergency safety checks of buildings.
In 2012 the company formed an agreement with Chiyoda-ku governmet to receive stranded commuters in the event of a large-scale disaster.
See the following for the number of buildings that have been designated as temporary shelters for stranded commuters.
Business Continuity Plan
The Mitsubishi Estate Group has drafted a Business Continuity Plan (BCP) to prevent crucial operations from being interrupted if a disaster or accident occurs — and, if they are suspended, to enable their speedy resumption — and we established "Mitsubishi Estate Group Business Continuity Plan Guidelines" in October 2006.
In December 2012, we established "Mitsubishi Estate Business Continuity Plan Documents" and the "Mitsubishi Estate Group Guide to Preparing a Business Continuity Plan Document" in light of the Great East Japan Earthquake. By strengthening the bonds between the Business Continuity Plan and the Framework of Anti-Disaster Measures, we are ready to ensure both the safety of customers and Mitsubishi Estate Group employees as well as the business continuity of the Mitsubishi Estate Group in an emergency.
Furthermore, in light of changes in the social and business environment, we strive to continually upgrade the content of the Business Continuity Plan through PDCA cycles and will implement further improvements going forward in order to fulfill our social responsibility.
Prompt Building Diagnoses and Restoration Measures During Disasters
When a major disaster, such as an earthquake, occurs, prompt building diagnosis and restoration work are required. Mitsubishi Estate worked together with the group company Mitsubishi Jisho Sekkei Inc., developing a framework for cooperating with various construction companies and strengthening further our frameworks for ensuring the safety and security of tenant companies and visitors.
The Mitsubishi Estate Group owns and manages numerous large buildings in locations that include the Marunouchi area. Because building maintenance and other maintenance work occur on a daily basis, many construction companies have developed support systems. By taking advantage of the unique strengths of the Mitsubishi Estate Group, which has specialized technical personnel stationed in its buildings, we have established a framework for rapid building diagnosis and restoration in times of disasters on the basis of the cooperative relationships we have developed day after day.
In specific terms, our disaster preparedness measures involve collaboration with construction companies, including cooperation with building emergency risk assessment personnel as long as the companies' business continuity plans are not hindered (inspecting building exteriors, locations that pose fire hazards, and vital facilities); cooperation on emergency repairs to ensure building safety; cooperation on inspections to determine the level of damage to building facilities; cooperation on proposals for disaster recovery plans, and the provision of emergency response supplies.
Establishing Building Safety Management Systems and Independent Guidelines
Mitsubishi Estate has established a Safety Management Office within its Facility Management Planning Department, and we have partnered with Mitsubishi Jisho Property Management and other group companies to continuously carry out daily inspections and safety inspections at buildings all across the country that are managed and operated by the Mitsubishi Estate Group. Additionally, we carry out centralized management of activities and data at each location, including safety inspections and improvements, and implement preventive safety measures by sharing accident data within the Mitsubishi Estate Group, and providing instructions and support as necessary.
We collect building-related accident data, including data from other companies, in order to rapidly investigate the cause of accidents and determine whether corrective measures are required. This information is shared promptly to prevent the recurrence of accidents. Based on our experiences from the Great East Japan Earthquake, we organize this data according to what responses have been taken, what reinforcements are needed, and what items need to be reviewed, and we push for ongoing improvements to our safety response measures. We have also created Building Safety Design Guidelines that contain standards independently established by our company, guidelines stricter than the Building Standards Act and other laws and regulations, that are applied right from a building's design stage to preemptively avoid accidents, and we conduct reviews of these guidelines as needed.
Conducting Regular Lifesaving Classes for Employees
Regular lifesaving class in progress (fiscal 2019)
Mitsubishi Estate has been continuously conducting regular lifesaving classes (including AED training) for disaster response staff since September 2008, and we were recognized as a "Certified Excellent Lifesaving Class Attendance Business*" by the Tokyo Fire Department in February 2009.
- Granted to businesses with at least one qualified first aid instructor and where at least 30% of employees complete regular lifesaving classes
See the following for the rate of employees with first aid provider qualification
Holding Comprehensive Emergency Drills in Private-Public Collaboration
Every September, Mitsubishi Estate holds comprehensive emergency drills with the participation of all of its executives and employees and many others from Group companies and other parties. This tradition dates back to 1923, when the Great Kanto Earthquake struck Tokyo and the Estate Department of Mitsubishi Goshi Kaisha, the precursor of Mitsubishi Estate, provided emergency aid, primarily from the former Marunouchi Building, which had been completed that year. Building on this experience, disaster response drills have been held regularly since 1926.
In 2019, the 93rd drill was carried out. Held in the neighborhood of Marunouchi, where the Mitsubishi Estate Group owns about 30 buildings, the drill assumed a scenario in which Marunouchi had been affected by an earthquake similar in magnitude to the Great East Japan Earthquake. With the invocation of the Anti-Disaster System, all employees took on their pre-planned roles as disaster response staff and practiced initial response, safety verification, information compilation, and equipment operations.
In fiscal 2019, in addition to annual training in the emergency healthcare collaboration with Chiyoda Medical Association and St. Luke's MediLocus and firefighting training carried out in collaboration with the responsible fire department and local firefighting brigade, Mitsubishi Estate conducted training on healthcare collaboration assuming emergency use of security robots with the ability of autonomous travel. Further, there was training on reception of foreigners in shelters for stranded commuters to ensure safety of tourists visiting Japan and foreign workers in an emergency.
In fiscal 2020, the drill was carried out based on the perspective of mitigating COVID-19 infection risk. It was implemented with the actual number of employees working based on infection control measures in mind and included an initial response in an environment with limited personnel and the collection and communication of information using tools such as the safety confirmation system and online conferencing.
Going forward, we will continue to work with the local fire department, as well as our buildings" corporate tenants, to keep enhancing the safety and security of Marunouchi and other neighborhoods where the Group has its presence by ensuring there are adequate systems in place for emergencies.
Information Delivery Testing Conducted Utilizing Disaster Dashboard 3.0 Assuming an Earthquake Directly Beneath Tokyo
As part of disaster preparedness efforts in the Otemachi, Marunouchi, and Yurakucho districts (collectively known as the Otemachi, Marunouchi and Yurakucho area), Mitsubishi Estate conducted a verification test of Disaster Dashboard 3.0 during January 2020 in collaboration with Chiyoda-ku, railway and bus operators, and building management.
Many commuters are expected to be stranded in the area if an earthquake occurs directly underneath the capital. The test was implemented to verify the usefulness of the next-generation disaster preparedness centers*1 established in the Otemachi, Marunouchi and Yurakucho area to help in working together with Chiyoda-ku to deal with stranded commuters. The test was conducted to deliver live footage of the area and text information from the Chiyoda-ku Emergency Response Headquarters and the disaster preparedness centers in four languages (English, Chinese, Korean, and Japanese) as well as TV news using approximately 100 digital signage boards of the Marunouchi Vision broadcast network. The test was also conducted to stream vacancy information on facilities that receive stranded commuters as well as the content above through an online version (two types: general use, emergency response agency use).
While Mitsubishi Estate has already signed an agreement with Chiyoda-ku to receive stranded commuters in the Otemachi, Marunouchi and Yurakucho area, going forward, the company aims to achieve information hub functionality at the next-generation disaster preparedness centers and build a framework that enables streamlined information sharing via ICT technologies in case of an earthquake directly beneath the capital. The company also promotes consideration of how ripple effects can be made to affect surrounding areas in order to further strengthen disaster preparedness.
- Disaster preparedness centers intended to further enhance disaster contingency plans in the Otemachi, Marunouchi and Yurakucho area as detailed in the Urban Redevelopment Security Plan (explained later*2). In the event of a disaster, these centers provide wide area information and local information as needed to stranded commuters and emergency response agencies via information hub functionality to support rescue efforts of injured individuals and handling of stranded commuters. These centers could also be used for human interaction with emergency response agencies and emergency drills in the area at ordinary times.
- At the Otemachi-Marunouchi-Yurakucho Area Urban Redevelopment Security Plan Conference in March 2015, the plan of the same name was approved and launched. Revisions such as information hub functionality were added in March 2019.

Disaster Response Drill Utilizing 5G Next Generation Communications Standard
On March 11, 2019, eight years after the Great East Japan Earthquake, Mitsubishi Estate held an initial response drill for employees at its head office, based on the action plan following the disaster system automatic announcement, to make use of the lessons learned from the earthquake.
This drill also doubled as Japan's first verification test for a disaster response drill utilizing a fifth-generation mobile communications system (5G). With cooperation from SoftBank Corp., we installed Odekake 5G, portable 5G equipment that allows 5G communications locally, and verified a system for monitoring conditions in evacuation centers in real time, using AI imaging analysis software.
In the verification testing, we transmitted images from IP cameras set up in two evacuation centers through the 5G network, and confirmed the visualization of a range of information in real time. This information included (1) the number of evacuees in evacuation centers, the number rescuers, and their attributes (sex and age, etc.); (2) crowding in evacuation centers; (3) results of identification of rescuers using facial recognition; and (4) results of detection of people in need of help.
In addition to saving labor at evacuation centers, the utilization of 5G is expected to facilitate diverse decisions and responses to a disaster such as guiding survivors to evacuation centers according to degree of crowding, appropriate assignment of rescuers, and selection of the number and types of supplies required.

Disaster Resilient Urban Development Leveraging Collaboration Between Mitsubishi Estate Residence and Academia
Industry and academia partnership agreement signing ceremony
Mitsubishi Estate Residence and Kyorin University are collaborating on disaster prevention initiatives, contemplating what universities, local governments, and businesses can do to develop contingency plans for the local communities. Together with Portland State University in the U.S., Kyorin University has worked on the Disaster Resilient Urban Development fieldwork program since 2017 in the Sanriku region affected by the Great East Japan Earthquake and in Tokyo in preparation for an earthquake directly striking the capital. A part of this program entailed a tour in June 2019 of a condominium in Kanade no Mori, a residential district offered by Mitsubishi Estate Residence in Narashino, Chiba Prefecture. At this location, visitors studied the efforts by the Mitsubishi Estate Group and shared ideas on urban development focusing on disaster resilience. The company also held a workshop where local residents were invited to the university to work together and discuss disaster contingency plans for the town.
In February 2020, a disaster contingency partnership agreement was signed as a way to further enhance disaster preparedness. In addition to emergency drills, workshops, and lectures, this initiative resulted in greater collaboration in the form of English versions of disaster preparedness tools designed for foreign nationals living in Japan, such as Sonaeru Drill (a disaster preparedness workbook) and Sonaeru Karuta (a disaster preparedness card game).
In order to build disaster-resilient communities, an approach articulated in Resilience, one of the Key Themes of the Mitsubishi Estate Group 2030 Goals for SDGs, the Group collaborates with its partners on disaster preparedness initiatives and promotes disaster resilient communities and urban development.
