Mori Building Co., Ltd.

Basic Concept

Since its establishment, the Mori Building group has been promoting urban development together with local residents under the philosophy of "Create Cities, Nurture Cities."
Under the Vertical Garden City multipurpose urban redevelopment and with the key themes of "Safety and Security," "Environment and Greenery," and "Culture and Art," the Mori Building group is committed to contributing to the community and society through urban redevelopment that enables sustainable social development, that is both disaster-prepared and environmentally friendly. In the belief that "a city begins when it is completed," the Mori Building group also promotes event management, community activities, and volunteer activities to revitalize the community in the completed city and surrounding areas. Furthermore, by encouraging its employees to participate in volunteer activities, the group strives to cooperate and coexist with society and the local community, as well as to enhance their values.
In keeping with Mori Building's belief that "to create cities is to take responsibility for the future of the people who live there," the Mori Building group is committed to continuously enhancing its corporate value and contributing to the development of a safe and prosperous society and region through its initiatives to "Create Cities, Nurture Cities."

The Mori Building Group Basic Policy on Social Contribution Activities

The Mori Building Group Compliance Code of Conduct Guidelines (Excerpt)

II. Relationship with Society: 2. Contribution to Society, Cooperation and Communication with Society
1) We shall strive to cooperate and coexist with the society and region, and contribute to the development of a safe and prosperous community by promoting employee participation in volunteer activities in the society and region.
2) We shall contribute to the development of a prosperous society and a rich urban life through activities that support culture and art.
3) With regard to laws and regulations etc. that have become unreasonable due to changes in the environment of the times etc. or have diverged from the reality of business activities, we shall communicate the problems to society from a practical business standpoint and actively discuss them so that we can work toward their revisions etc.

Support for Employee Volunteer Activities

Mori Building strives to create work environments that facilitates employee volunteer activities, including volunteer leaves.

Outline of Main Systems

  • Leaves for self-development (volunteerism)
    Employees may use up to 20 days of accrued paid leave per year for volunteer activities.

Urban Redevelopment Project Initiatives

The Mori Building group's urban development begins by discussing the future of the city with the residents who live there. The most important thing is to pursue the ideal city without making any compromises and to build a true relationship of trust with the local residents. No project can be realized without enthusiasm for a better future and a relationship of trust between the people who make up the city.

The base model for urban development is the "Vertical Garden City." By bringing subdivided cities together in one place, a large space is created, and when buildings are made super high-rise, a large area of open space can be created at the foot of the building to increase green space. Moreover, by creating a compact city where buildings are not used exclusively for offices or residences, but are highly complex with a variety of urban functions concentrated within walking distance, a variety of people will gather in the city for various purposes such as living, working, recreation, learning, and relaxing, and this will create opportunities for interaction, collaboration, and emergence. This is the product of an idea completely opposite to conventional urban development based on the differentiation of uses.

In addition, the Mori Building group views the completion of a building as a beginning, not an end, so it nurtures the cities with utmost care. In line with its philosophy "Create cities, Nurture cities," the Mori Building group has built up a consistent organization, experience, and expertise in development and town management. While the freshness of a building decays with the passage of time, the bonds with the people involved there deepen over time. The Mori Building group believes that both development and town management are essential to enhance the magnetism of a city.

ARK Hills (completed in 1986): The Starting Point of Mori Building's Urban Development

ARK Hills (completed in 1986)

The ARK Hills is the first large-scale private redevelopment project in Japan, consisting of offices, residences, a hotel, and a concert hall, and it is the starting point of the Hills, which over the past 17 years has embodied the close proximity of workplaces and residences, the transmission of culture, and the harmonious coexistence of cities and nature. In the more than 30 years since its opening, the ARK Hills has continued to create values that lead the times in a variety of settings, including business, residences, culture, greenery, and community. In 2019, Suntory Hall received the Building and Equipment Long-life Cycle Association's BELCA Award for its 30-plus years of contributions to architectural and musical culture.
The area with the ARK Hills as its core has been continuing to be developed through numerous large-scale redevelopment projects and transportation infrastructure improvements, and is constantly innovating and improving, while increasing its maturity.

Roppongi Hills (completed in 2003): The Cultural Heart of Tokyo

Roppongi Hills (completed in 2003)

The Roppongi Hills is a large-scale urban redevelopment project that represents Japan in both name and actuality, and is a global urban model that embodies Mori Building's "Vertical Garden City." It has become a stage for the urban activities of more than 40 million global players and visitors annually, and has always created and disseminated cutting-edge culture and information based on the concept of the "Cultural Heart of Tokyo." Even now, 20 years after its opening, the Roppongi Hills continues to grow as a top-runner, attracting the world with its great magnetism and strongly leading the urban reconstruction of Tokyo.

Toranomon Hills (in progress): New International Hub and Global Business Center

Toranomon Hills (in progress)

The Toranomon Hills area, which saw the opening of Toranomon Hills Mori Tower in 2014, Toranomon Hills Business Tower in 2020, and Toranomon Hills Residential Tower in January 2022, will be developed with the addition of Toranomon Hills Station Tower (scheduled for completion in July 2023) which will be developed together with Toranomon Hills Station on the Tokyo Metro Hibiya Line, as well as expanded to approximately 7.5 hectares in total area with a total floor area of approximately 800,000 square meters. It will evolve into an urban complex with a variety of urban functions within walking distance, including world-class offices, residences, hotels, retail facilities, an incubation center, transportation infrastructure, and green space, and will drive the further enhancement of the magnetism of Tokyo as a truly international new international hub with an impact comparable to that of Roppongi Hills.

Azabudai Hills (in progress): "Hills of the Future" with Overwhelming Scale and Impact

Azabudai Hills (in progress)

The concept of the Azabudai Hills is a "Modern Urban Village," which aims to be a huge open space surrounded by greenery that brings people together. The two pillars supporting this concept are Green and Wellness. The vast project area of approximately 8.1 hectares is surrounded by an overwhelming amount of greenery, with a green area of approximately 2.4 hectares, including the central square of approximately 6,000m². It aims to create a new community where a diverse range of people can gather and live in an environment in harmony with nature, where diverse urban functions such as offices, residences, hotels, an international school, retail facilities, and cultural facilities are highly integrated.
This project is the ideal "City within a City (compact city)," and also is the "Hills of the Future," in which everything it has accumulated in the Hills development to date has been incorporated.

Urban Development for Safety and Security

"Safety and Security" are the most important and urgent issues for Japan, a country prone to earthquakes, typhoons, and other disasters. The probability of an earthquake expected to directly strike the capital city of Tokyo has been increasing in recent years. The revitalization of Tokyo as a disaster-resistant city is essential to protect our lives and property, as well as to enhance the magnetism of Tokyo. Mori Building is creating a safe and secure city that is resilient to disasters by taking advantage of the characteristics of large-scale redevelopment under the concept of "Cities to escape to, rather than flee from." It is creating a disaster prevention base that will contribute to not only the development area but also to the surrounding community. In addition to the creation of open spaces and the development of urban transportation infrastructure, it is actively working to secure space for a total of 10,000 evacuees, stockpile food, materials, equipment, and other resources, and provide information.

The Mori Building Group Compliance Code of Conduct Guidelines (Excerpt)

II. Relationship with Society: 4. Creation of Safe Facilities and Services (three articles of safety)
1) We shall prioritize safety and security above all else and it will act as the foundation that supports all the attractions of the city.
2) In order to ensure safety and security, we shall be aware of problems in all departments and operations, and aim for more reliable technology and management with a sincere attitude.
3) We shall constantly monitor and improve our actions by taking responsibility for personal conduct in order to enhance safety and security.

III. Relationship with Customers, Suppliers and Competitors: 9. Provision of Safe Facilities and Services, etc.
1) In providing, developing, managing, selling, and operating facilities and services, we shall always pay attention to safety as a major premise for customer (this refers to all tenants, residents, and other users of facilities and services. The same applies hereinafter) satisfaction and trust, and shall fully understand and comply with laws and various standards related to facilities and services, while aiming for a higher level of safety.

Basic Policy on Earthquake Countermeasures

  1. We shall place the highest priority on the safety of our tenants, residents, visitors, neighbors, and our employees who use the buildings and facilities owned, managed, and operated by Mori Building.
  2. We shall respond as quickly as possible to minimize damage in the event of an earthquake disaster.
  3. We shall maintain support functions for tenants to continue their work and residents to continue their lives.
  4. We shall cooperate with neighboring communities, the Tokyo Metropolitan Government, Minato City, the police, fire departments, and other relevant government agencies to contribute to society.

Consolidating Buildings to Create Large Spaces

In past earthquakes, old wooden houses in dense areas suffered extensive damage due to the collapse of houses and the spread of fire. Therefore, areas with dense wooden housing are in urgent need of redevelopment in preparation for the event of expected earthquakes. With the rising potential for the occurrence of earthquakes occurring directly beneath the Tokyo Metropolitan Area, the importance of building a city capable of withstanding disaster grows in urgency.
Mori Building's redevelopment method, which integrates subdivided land and concentrates dispersed buildings into high-rise buildings, is extremely effective for urban disaster prevention, including the development of dense areas of low-rise wooden buildings. By integrating low-rise wooden buildings in a dense area with high-rise buildings that are earthquake-resistant and noncombustible, and developing them together with wide-area roads and other infrastructure, evacuation space will be created at the foot of the buildings, thereby improving the disaster preparedness of the entire area. Mori Building will make effective use of limited urban space and create generous spaces and green areas for people to relax while realizing a safe and secure lifestyle for all.

Thorough Disaster Prevention Measures from Tangible to Intangible Aspects

Mori Building has equipped its buildings with the highest level of anti-seismic performance currently possible, such as vibration control walls and vibration control dampers, and has also installed a private power generation system in case of emergency. The company position our developments to serve as community shelters by providing emergency wells and emergency supply warehouses, as well as conducting regular disaster drills throughout the block.

Receiving Stranded People

Mori Building has organized a system to receive approximately 10,000* stranded people at its large-scale facilities. Roppongi Hills and Toranomon Hills have the "Agreement for cooperation in sheltering individuals who are unable to return home in the event of a disaster" with Minato City, and are striving to create a safe and secure city that is resilient to disasters that also serves as a disaster prevention center for the surrounding area under public-private partnership.
In the event of an earthquake, a large number of temporary visitors, including stranded people, are expected to be in the vicinity of Roppongi Station, and there are concerns about secondary disasters such as obstructions to rescue operations, aftershocks, and crowd accidents. Therefore, Mori Building has joined the "Council for preparedness for temporary visitors around Roppongi Station," which consists of the Minato City Government, fire department, police department, railroad companies, and local businesses, and is working together to improve disaster preparedness in the area.

  • The estimated numbers of people are: 5,000 at Roppongi Hills, 4,600 at Toranomon Hills, and some others at ARK Hills Sengokuyama Mori Tower, and at Omotesando Hills, etc.

Education Activities for Office Workers and Store Tenant Staff

The company distributes its "Earthquake Countermeasures Handbook"* to personnel in corporate offices and retail facilities to raise awareness in the case of an emergency.

  • Examples of contents included in the booklet are: simultaneous return home restraints, thorough implementation of firefighting plans, methods for confirming the safety of employees and their families, ensuring safety in offices and stores, and preparing stockpiles of supplies

Consideration for Access to Public Transportation

Mori Building strives to improve and enhance local infrastructure through large-scale urban redevelopment projects.
In the space created by integrating subdivided land through redevelopment, consolidating dispersed buildings and making them into high-rise buildings, Mori Building is promoting the development of district highways, the installation of route bus stops and bus terminals, and the construction of connecting pathways leading to the nearest train stations. In addition, it is working to promote the separation of sidewalks and roadways by creating a car-only flow line within the site, and to make the pedestrian space barrier-free so that everyone can move around comfortably.

Collaboration with Stakeholders

Amid concerns about the weakening of local human ties and the reduction of opportunities for interaction due to the declining population, declining birthrates, and the aging of society, the Mori Building group has worked throughout "the city" to create a variety of opportunities for interaction, connecting people who live, work, and visit there.

Based on a relationship of trust with local residents that we have built over many years through redevelopment projects, Mori Building has become the unified manager of "the city" and has continued to pursue the optimal solution of "one city" by responding to ever-changing local issues and user needs, as well as coordinating the interests of the various members of the city and facilities with different uses.

In addition, Mori Building has established the residents' association as a core organization for community activities to promote urban development in cooperation with the surrounding area. The residents' association has inherited the foundation of the redevelopment association, which has led the urban redevelopment project for more than a decade, while welcoming new residents and workers from stores and businesses to the area. Mori Building is involved in a variety of activities with the goal of creating an open community where people of diverse nationalities, occupations, and ages can actively participate in local activities, which is only possible in a mixed-use urban complex.

Major initiatives at the Roppongi Hills

Roppongi Hills Earthquake Drill

Mori Building conducts a comprehensive disaster prevention drill every year in March in cooperation with people involved in the city, with the aim of becoming a "city to escape to" in the event of an earthquake disaster. The drill includes a check of the emergency water wells in the Hills, emergency supplies, and building structure, as well as hands-on training in first aid.

Roppongi Hills Spring Festival and Bon Odori Dance

Twice a year, Roppongi Hills holds a festival organized by its residents' association as a local community event for residents to "create, participate, and enjoy." In the Spring Festival, held in conjunction with the cherry blossom season, the cherry trees in Mohri Garden and Sakura-zaka are lit up, and food stalls from Hills tenants and TV Asahi are set up in the Mohri Garden. For the Summer Bon Odori Dance, which attracts many people of all ages, nationalities, and places of residence every year, a dancing stage is set up in the Roppongi Hills Arena, where the Hills tenants and TV Asahi food stalls are also set up. Mori Building is working to promote community collaboration by holding the Bon Odori Dance at the same time as the nearby Azabu Juban Noryo Matsuri Festival.

Roppongi Hills "GREEN UP"

Since 2012, the Roppongi Hills has been holding "GREEN UP" activities for residents of its offices and residences with the aim of deepening their attachment to the Roppongi Hills and encouraging communication among participants, through the planting and maintenance of flower beds. The activity is held once a month in the morning and has been well received by participants, who find it a meaningful way to spend their time before going to work or going out.

"Hills Breakfast" at the Roppongi Hills

The "Hills Breakfast" is one-hour talk event held in early morning once a month at the Roppongi Hills. Approximately 120 events have been held since its inception in 2010 (by the end of 2021), with a total of more than 600 speakers and more than 20,000 participants. The event has become a place for office workers to create new ideas, and has now become an opportunity for participants to connect across boundaries, with participants volunteering to help run the event, and participants who empathize with the speakers becoming friends and launching new spin-off activities.

Roppongi Hills Neighborhood Association

The Roppongi Hills Neighborhood Association was established in May 2004 to foster community among the residents and workers of Roppongi Hills, and to promote a culturally and internationally rich community in cooperation with neighboring community associations. In order to make Roppongi Hills a safe, secure, and pleasant place to live, the association actively engages in activities such as the monthly volunteer "Roppongi Clean-up", the Spring Festival, Bon Odori Dance, and earthquake drills.

Three pillars of Neighborhood Association activities

  1. Safety and Security Activities
    The main purpose of the residents' association is to create a safe and secure community that can respond to "self-help, mutual-help, and public help." In cooperation with other neighborhood associations, the Neighborhood Association engages in crime and disaster prevention activities with the aim of creating a city where residents can help each other not only in the event of an earthquake, but also in their daily lives.
    Examples of activities: Earthquake drills, initiatives to address traffic issues, etc.
  2. Community Activities
    The Neighborhood Association conducts a variety of activities throughout the year in the hope that residents make many acquaintances (networks) within the Hills through community activities. The networks formed through community activities are important bonds that can also be useful in times of emergency.
    Examples of activities: New year's party, Spring Festival, cherry blossom viewing party, morning Tai Chi, Bon Odori Dance, autumn gathering, cross-cultural exchange program, etc.
  3. Community Contribution Activities
    Based on one of the themes of the residents' association "not only to stay in the Roppongi Hills, but also to revitalize the entire Roppongi area," it proactively takes part in activities in the Roppongi area.
    Examples of activities: clean-up activities, various roles in the neighborhood, etc.

Support for Culture and the Art

The Mori Building group is committed to urban development with culture as one of the most important elements, based on its strong belief that a city must have cultural attractions that not only support economic activities but also enrich urban life. Culture creates new value in society and is the driving force that moves the world.

In 1986, Mori Building developed a compact city, the ARK Hills, with a high concentration of offices, residences, retail stores, a music hall (Suntory Hall), an educational institution for working adults (ARK Toshijuku), a membership club (ARK HILLS CLUB), a hotel, and a rooftop garden. In 2003, based on the concept of the "Cultural Heart of Tokyo," it also developed Roppongi Hills and established the Mori Art Museum, as well as an educational institution for working adults and a members-only library (Roppongi Academyhills), a members-only club (ROPPONGI HILLS CLUB), on the top floor of Roppongi Hills Mori Tower. Furthermore, through means of town management methods, it has organized various cultural and exchange events, including Roppongi Art Night, and has been disseminating its cultural offerings to the world. In 2018, Mori Building opened the world's first DIGITAL ART MUSEUM in Odaiba, Tokyo, which has been highly acclaimed by people around the world as a unique and one-of-a-kind cultural facility.

The ARK Hills redevelopment project was completed in 1986, 17 years after Mori Building began its quest to find a way to create a city that not only supports economic activity, but also offers cultural attractions and a rich environment. The ARK Hills is a super high-rise compact city combining offices, residences, a music hall (the Suntory Hall), hotels, restaurants, stores, a membership club, and adult education, and is an urban development project that aims to combine economic and cultural activities. The presence of a first-class music hall and educational and social exchange facilities has attracted a different type of people to the city than those who only work there, and has brought about the city's enrichment, vitality, and attractiveness. The Suntory Hall, which was created based on the concept of the most beautiful sound in the world, continues to welcome many people to the city.

The concept of "creating the cultural heart of Tokyo," which was born from the experience of ARK Hills, was carried over to Roppongi Hills and has blossomed.
Roppongi Hills is a compact city that integrates a variety of urban functions such as work, residence/living, commercial/retail, relaxation, recreation, education, childcare, and medical care, as well as various cultural devices to foster encounters, exchanges, and dialogues among people. It has ventured to gather on the top floor of Roppongi Hills Mori Tower an art museum (Mori Art Museum), a members-only private club (ROPPONGI HILLS CLUB), an educational institution for working adults (Roppongi Academyhills), a members-only library, and other facilities as a symbol of the cultural heart of Tokyo.
The Roppongi Hills not only nurtures culture, but also serves a variety of functions to disseminate it both domestically and internationally. It is equipped not only with existing media such as television and radio stations, but also with tangible and intangible systems that view the city itself as a media outlet. It has become the destination that people around the world visit in search of its attractions, as a place where something new is always happening, and where new knowledge, creativity, and possibilities are always being born.

Public Art

As part of the idea to make Roppongi the cultural heart of Tokyo, Roppongi Hills has installed public art and street furniture throughout the site, specially created by more than 20 world-class artists and designers. These beautiful and functional works of art and design transcend the boundaries of art and design to form the creative landscape of the cultural heart of Tokyo.
In addition to this, public art is actively incorporated in ARK Hills and Toranomon Hills, creating an environment where people who live, work, play, and participate in the city can lead a more fulfilling and enriched everyday life through contemporary art and creative experiences.
