Establishment of Disaster Preparedness and Mitigation Framework

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 the Chiyoda-ku government 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.

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.

Testing Conducted for Disaster Dashboard 4.0 for Earthquake Directly Beneath Tokyo × Infectious Disease Control Measures × Digitization

As part of disaster preparedness efforts in the Otemachi, Marunouchi, Yurakucho area, Mitsubishi Estate conducted a verification test of Disaster Dashboard 4.0 in collaboration with the local Chiyoda-ku government, railway and bus operators, and building management from late-January through early-February 2021. Disaster Dashboard 4.0 further strengthens the functionality of the Disaster Dashboard 3.0 platform released in January 2020 for sharing information in the event of a disaster and delivering information to stranded commuters.

Many commuters are expected to be stranded in the area if an earthquake occurs directly underneath the capital. The test was implemented with the objective of achieving the information hub functionality in the next-generation disaster preparedness centers*1 in the area with the purpose of supporting corporate BCPs, helping stranded commuters, and aiding in the transportation of the injured. Contactless check-in and check-out using QR codes were made available at shelters for stranded commuters that are offered in collaboration with the Chiyoda-ku government. In addition, mechanisms for managing the health status of the incoming people and contacting them individually were made possible as measures to control the spread of COVID-19. A verification test was conducted in which graphs showing the number of stranded commuters and vacancy information linked to the number of people accepted were displayed in real time on approximately 100 digital signage boards installed in the area as well as online screens.

While Mitsubishi Estate has signed an agreement with Chiyoda-ku to receive stranded commuters in the Otemachi, Marunouchi, Yurakucho area, going forward, the company will boost public-private and private-private partnerships through the Disaster Dashboard to realize next-generation disaster preparedness center functionality in the event of a major earthquake striking the capital. Further, it will facilitate an emergency rescue system for the injured using infection control measures, thereby continuing to further strengthen disaster preparedness in this area.

  • Disaster preparedness centers intended to further enhance disaster contingency plans in the Otemachi, Marunouchi, 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 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.

Participatory Emergency Drill Using Online Resources with Nearly 2,300 Households in Kanade no Mori

Streaming the Safety Confirmation Drill

Online workshop

In March 2021, Mitsubishi Estate Residence and Mitsubishi Jisho Community conducted an online-focused emergency drill in the Kanade no Mori area in Narashino, Chiba, together with Kanade no Mori Partners, an area management organization.

The emergency drills in this area began with The Parkhouse Tsudanuma Kanade no Mori, a condominium offered by Mitsubishi Estate Residence, and this most current drill marks the sixth such drill. Currently, there are nearly 2,300 households participating, including those from properties sold and managed by other companies. Due to the growing COVID-19 pandemic, online resources were utilized, enabling us to continue this large-scale area emergency exercise.

The following three online programs were offered. The first was the Safety Confirmation Drill and Emergency Supply Storehouse/Regional Emergency Facility Live-Stream. During this program, activities related to operation of emergency response headquarters were streamed live, allowing residents to see and learn about a facet of operations that they usually do not have access to. The second program was Learning About Stockpiling and Cooperation for Families, where participants were encouraged to think about stockpiling supplies at home and assisting area residents. The third program was a demonstration entitled Stockpiling for Everyday Use, which was streamed from the homes of condominium residents, offering specific ways to stockpile necessities and inspiring them to take action.

The Mitsubishi Estate Group is focused on connecting the entire community in emergency preparedness and mitigation, promoting disaster-resilient urban development by collaborating and working together with many different people.

Additionally, the flood preparedness version of Sonaeru Karuta (a disaster preparedness card game) was created in February 2021 as a way to help deal with the recent frequent flooding, and is now available to the public.

The water preparedness version of the Sonaeru Karuta card game was released on February 25, 2021.
