Providing Value through Customer Satisfaction
and Creation of Neighborhoods

Policy of Enhancing Customer Satisfaction

As part of our Environmental Initiatives Policy, we have set cooperation (collaborating and cooperating with various stakeholders) as one of our key activities. In collaboration and cooperation with customers, business partners, local communities, and the authorities, we will ensure we respect human rights in our business activities.

We are also a participating party in the Declaration of Partnership Building project, established by the Japanese Cabinet Office and other entities. The project aims to help large corporations and small and medium-sized enterprises form sustainable relationships that will help both to grow. By participating, companies declare that they will promote co-prosperity throughout entire supply chains and form new partnerships that go beyond the current scale, groups and borders, etc., as well as complying with positive trading practices with main operators and subcontractors.

We recognize that our employees and the employees of tenants of our facilities are also important partners, and we will work on efforts such as utilizing proactive dialogue to help each individual stay healthy and safe, and to provide them with opportunities to develop their abilities.

Declaration of Partnership Building

In order to form a new partnership that will help us cooperate, and aiming for mutual prosperity, with the business partners that form our supply chain and companies that help us create value, we declare our intent to focus our energies on the following:

1.  Promoting co-prosperity throughout the entire supply chain and forming new partnerships that go beyond the current scale, groups and borders, etc.

Through our direct business partners, we have put pressure on partners further down the supply chain (moving them from Tier N to Tier N+1 business partners) to work on improving added value throughout the chain. Also, through existing business partnerships and cross-company collaboration, etc., we are aiming to develop a framework that brings prosperity for both us and our partners. We have also supported our partners by offering advice on introducing teleworking or formulating business continuity plans (BCPs) from the perspective of responding to disasters or reforming the way people work.

Individual initiatives:

a. Cooperation between companies

Based on the ideal of coexisting in harmony with society symbolized by our アンド logo, we will promote our business hand in hand with our business partners. Equally, we are working with those same partners to create new industries through open innovation.

b. Environmental efforts

In addition to formulating a Group action plan to realize a decarbonized society, the whole supply chain is working together to implement five initiatives: (1) improving the environmental friendliness of new construction projects and existing properties; (2) using environmentally friendly electricity in shared areas and areas that our businesses use in buildings; (3) providing environmentally friendly options to business tenants and buyers; (4) securing a stable supply of renewable energy; and (5) reducing CO2 emissions produced during construction.

2.  Complying with promotion standards

For positive trading practices with new main operators and subcontractors, we comply with promotion standards based on the Act on the Promotion of Subcontracting Small and Medium-sized Enterprises and are actively working to combat trading and business practices that interfere with our efforts to build partnerships with our business partners.

(1) Pricing methods

We do not make demands for unreasonably low cost prices. When determining costs associated with business dealings, where subcontractors wish to discuss prices, we debate the matter appropriately, with due consideration to how the subcontractor can achieve a suitable level of profit, with regard to the effect of rising labor costs and similar. The main operator specifies and issues contract terms and conditions, including decisions on prices, in writing and other formats.

(2) Bills and other payment criteria

We pay subcontractors' fees in cash.

(3) Intellectual property and expertise

During our dealings, we do not ask partners to disclose their expertise or transfer intellection property rights without monetary compensation where inappropriate.

(4) Negative effects of changes to working styles

To allow business partners to also adapt to new working styles, we do not make inappropriate demands for unreasonably short deadlines or suddenly change specifications, which would result in a greater burden on the partner. In the event of a disaster, we would not force a subcontractor to take the entire burden of dealings, and where possible will consider how to resume our partnership when work can begin again.

3.  Other

Based on the ideals of coexisting in harmony with society, linking diverse values, and achieving a sustainable society, the Mitsui Fudosan Group is working to build societies that enrich people's lives and our planet. We pursue ESG management and conduct business with awareness of our responsibilities with respect to the Environment, Society, and Governance. Reflecting our commitment to further accelerate the Group's ESG management, we can contribute in a significant way to the Japanese government's Society 5.0 vision and to the attainment of the UN's SDGs. In November 2021, we formulated policies for the Group regarding how to help bring about a decarbonized society and how to promote diversity and inclusion. In the future, we will continue to work to address social challenges through neighborhood creation.

Our Efforts to Improve Customer Satisfaction (CS)

The Group emphasizes communication with customers, and we address customer feedback and requests with great seriousness. By working to resolve and address various consumer issues, we will promote neighborhood creation from the customer's perspective, and improve the quality of services provided to customers.

Major Initiatives

Listening to Customers

The Group undertakes a variety of activities as a part of efforts to listen to customers' comments. CS surveys are conducted encompassing a wide area including office building tenant companies and residents of condominiums and detached housing as well as hotel guests. The feedback gained through these surveys is extremely helpful in improving the Group's initiatives. We carefully monitor customer feedback received through boxes placed for this purpose at some of our retail properties. These opinions and comments are used to improve operations in facilities and other areas, including store planning and design.

Barrier-Free and Universal Design

For all aspects of life, whether it be work, home life, recreation, or relaxation, the Group promotes the creation of urban environments and buildings that are easy for everyone to use, regardless of their cultural background, language, nationality, age, sex, or disability. Moreover, in our office buildings and other development projects, we examine ease of access using public transport, and evaluate accessibility for people with disabilities. We ensure our measures are within the scope stipulated by laws and regulations, and in some cases make additional efforts.

Mitsui Home Co., Ltd.'s endeavor to make temperature and humidity equipment barrier-free was selected as a fiscal 2017 Leading Project for Sustainable Homes by the Ministry of Land, Infrastructure, Transport and Tourism. Seeking to make home life more healthy, secure, and convenient, the system combines duct-type air conditioning systems and IoT technology to suppress indoor dust and thereby reduce cleaning frequency. The project also enables users to do such things as remotely fill their bathtubs. In this way, the burden of housework and time spent are lessened.

Mama with LaLaport

The Mama with LaLaport campaign aims to ensure that parents and expectant parents have more fun and more peace of mind by making the shopping centers better oriented to mothers and fathers. As well as design features such as baby rooms and places where kids can play, we are also proactively working on initiatives such as events where parents can meet other parents and workshops both parents and children can enjoy. In 2022, these efforts were recognized by the Japan Mothers Association's Mothers Selection Awards.

Examples of major initiatives:

  • Facilities inside LaLaport shopping centers to benefit those bringing up children, including nursing rooms, baby changing stations, kids' spaces, raised floor seating, and wide, open spaces indoors and out.

Efforts to Improve Employee Satisfaction (ES)

We strive to improve the functionality of the facilities used by our employees and create a comfortable working environment based on the idea that employees working at facilities are valued partners and that providing a comfortable working environment to increase employee satisfaction (ES) leads to better service to customers and enhances customer satisfaction (CS).

Major Initiatives

The Mitsui Shopping Park Staff Circle is an initiative to create a comfortable working environment and an enriching community for store staff working at commercial facilities. This is achieved by introducing Hata Luck®, a store management application offered by Knowledge Merchant Works Co., Ltd.

We are also providing corporate-led childcare services at four childcare facilities attached to commercial facilities: Mitsui Outlet Park Kurashiki (Kurashiki City, Okayama), Mitsui Shopping Park LaLaport Nagoya Minato Acres (Minato-ku, Nagoya City), Mitsui Outlet Park Kisarazu (Kisarazu City, Chiba), and Mitsui Outlet Park Sendai Port (Miyagino-ku, Sendai City).

To improve the ES of employees working at commercial facilities, we are remodeling employee lounges. These cheerful, spacious lounges with a café atmosphere are decorated in a highly individualized style for each facility, and are restful spaces where employees can spend some relaxing time. Convenience has been enhanced by installing vending machines for food and convenience store products.

Creating New Value and Markets through Neighborhood Creation

The Group seeks to create new value and markets through the creation of neighborhoods with outstanding function and quality, while in constant pursuit of cutting-edge approaches. As such, we summarize our basic stance toward neighborhood creation with the following three points.The first is to integrate diverse functions and features, which involves promoting mixed use (combining applications and functions) and integrating the tangible and intangible aspects of the Group's operations. The second is to create communities, which entails connecting people who reside or gather in, or visit a particular area within that region, and the third is to work beyond the simple creation of neighborhoods to address specific needs as neighborhoods mature with age year after year through town management.

By establishing a virtuous cycle that comprises these three activity goals, we strive to create new value.

Our Efforts to Eliminate Redeliveries

In response to the sharp increase in package delivery volume, which is becoming a social challenge, Mitsui Fudosan Residential Co., Ltd. and Fulltime System Co., Ltd. have formulated a project to improve efficiency of delivery lockers at condominiums. The measures are outlined below:

  • Expand the number of delivery lockers to meet current needs through redesign
  • Raise the turnover rate of packages being placed in and removed from lockers
  • Reduce the number of deliveries made to lockers
  • Offer a locker status check service

These four measures will be progressively introduced at selected Mitsui Fudosan Residential Co., Ltd. properties to enhance delivery locker efficiency, beginning with Park Tower Harumi (Chuo-ku, Tokyo), a large-scale residence completed in 2019.

Safe and Secure Neighborhood Creation

The Group aims to ensure safety and security by creating disaster-resilient neighborhoods, while working to raise awareness of disaster countermeasures through routine training, inspection, and education. We go beyond simply protecting the safety of employees, tenants, and customers, and strive to expand and improve measures for disaster preparedness in collaboration with local communities.

Disaster Countermeasures System

To ensure safety and security for the employees, tenant companies, and visitors to buildings and facilities managed by the Group, Mitsui Fudosan is promoting disaster countermeasure drills and lectures, and business continuity planning (BCP). To ensure the safety of our employees and tenants, we implement training based on disaster countermeasure manuals and BCPs as part of our disaster countermeasures.

The Company maintains a dedicated Disaster Countermeasure Headquarters at the Nihonbashi Muromachi Mitsui Tower (Chuo-ku, Tokyo). Power is generated with gas from a medium-pressure line, which is highly reliable in disasters. This supplies the power required by the building's BCP, even in emergencies.

In the event of a major earthquake, we have in place measures to set up an emergency headquarters that reports directly to the president. To ensure that we are better prepared to respond to any disaster, employees in the disaster center take shifts and remain on duty during weekday nights and holidays. Our disaster response system coordinates with Group companies to ascertain the safety of employees and the status of damage to properties. Employees train in lifesaving procedures using automated external defibrillators (AED). By ensuring that there are certified employees at each worksite, we are working to raise the resuscitation rate for cardiac arrest.

Smart Energy Project

We are working to solve various social issues such as energy, environmental issues, and disaster prevention through urban development.

The "Smart Energy Project" has been launched was launched in 2019 starting in Nihonbashi. Through Mitsui Fudosan TG Smart Energy Co., Ltd., which was jointly established with Tokyo Gas Co., Ltd., an "energy center" centered on a large-scale cogeneration system fueled by city gas will be installed in a large-scale redevelopment building. This is an initiative to supply the generated electricity and air conditioning using the heat generated during the generation to the redevelopment and its surroundings.

In normal times, by effectively utilizing the heat generated during power generation, energy efficiency is improved, contributing to energy conservation and CO2 reduction in the city. In the event of a disaster (wide-area power outage), power is generated using gas drawn from highly earthquake-resistant pipes, and the supply of electricity and heating and cooling to the area is continued, improving the BCP performance of the supply building. Contribute to improving the disaster resistance of the city.

Smart energy projects have started operations in Toyosu in 2020 and Yaesu in August 2022, and we aim to realize a sustainable society by reducing the environmental burden and ensuring the safety and security of the city.

Kumamoto Earthquakes Research Report Distributed to Related Government Ministries and Agencies as Well as Universities

Since the Great Hanshin Earthquake of 1995, Mitsui Home Co., Ltd. has carried out inspections of all of its residences exposed to shaking of intensity 7 or greater. After the Kumamoto earthquakes of 2016, we sent over 1,600 people to investigate 1,263 Mitsui Home residences in the affected area, and published the findings in a research report. Of the buildings investigated, none were completely destroyed, and only 10 were slightly damaged. This result demonstrates the outstanding seismic resistance of Mitsui Home Co., Ltd.'s 2x4 design and construction methods. We distributed the report, published in February 2017, to related government ministries and agencies as well as universities, to share this earthquake-related data.

Improving the Quality of Urban Development

The Group works diligently to ensure the quality management of its buildings as well as every other facet of its business operations, including products and services, as the foundation for providing safety, security, and comfort to its customers. We are convinced that the delivery of quality-based security, safety, and comfort is a prerequisite for realizing customer satisfaction (CS).

Each business draws up its own design guidelines, manuals, etc. on quality management and puts them into practice to ensure that quality is managed thoroughly. The guidelines, manuals, etc. are also reviewed and revised as needed to reflect customer feedback, problems that have taken place, etc. Reviews of safety-related matters are carried out from time to time as well as following a disaster.

Our Efforts at Nihonbashi

The Nihonbashi Revitalization Plan for Preserving and Revitalizing Heritage while Creating the Future

Nihonbashi (Chuo-ku, Tokyo) has flourished as a center of commerce and culture since the Edo period. The Group's over three-hundred year history is closely associated with this area. To express our love and appreciation for Nihonbashi, we have begun the Nihonbashi Revitalization Plan with the concept of creating while retaining and reviving, to stimulate the area and make it even more attractive. We are collaborating with government, private enterprise, and local residents to create a new neighborhood that combines tradition and renewal.

Fukutoku Garden was established as a spacious plaza covering more than a thousand square meters among the buildings of Nihonbashi that are undergoing redevelopment. It is a restful spot which utilizes the nature of Japan to reproduce the history and tradition the area has fostered. The greenery surrounding the adjacent Fukutoku Shrine and its approach enables visitors to enjoy the beauty of the four seasons.

Creating Neighborhoods by Creating Roads in Nihonbashi

Nihonbashi in Tokyo flourished as the starting point of the five major highways leading to other parts of Japan. The Company is following a policy of Building Neighborhoods by Building Roads to avoid unplanned redevelopment in this area and ensure coexistence with the culture and tradition that is a product of Nihonbashi, with its historic buildings. As a first step, we are preserving the appearance of the area by unifying the height of the lower floors of buildings along Nihonbashi's iconic main street at 31 meters. Furthermore, by developing facilities and creating green spaces suited to the characteristics of the streets that have been loved in the area from the distant past, we are creating spaces for people to gather and enjoy themselves. Edo was known for its extensive network of canals, and by restoring some of this network as well, we are using the creation of roads as a point of departure to create the Nihonbashi of the future.

Hotel-related Initiatives

HOTEL THE MITSUI KYOTO (Nakagyo-ku, Kyoto), under the brand concept of "EMBRACING JAPAN'S BEAUTY," offers a space to stay blending traditional Japanese unique beauty found in traditional culture, architecture, craftsmanship, and food with contemporary design, harmonizing historical and progressive elements. The guestrooms are designed to resemble a traditional tea ceremony room, and has been created using natural materials and craftsmanship. In addition, the courtyard has a landscape design that respects the spirit of "Niwaya Ichijo".

The Mitsui Garden Hotel Kyoto Kawaramachi Jokyoji (Shimogyo-ku, Kyoto) will be a unique building complex in collaboration with a temple that preserves Kyoto's history and culture. Kyoto is dotted with numerous temples that are not only tourist attractions but also serve as spiritual places for the people living there. However, some temples have been forced to close due to aging buildings, lack of successors, and a decline in the number of priests. As one solution to these social issues, this project is a new model case of temple revitalization, in which a hotel and a temple development are integrated.

"WOODY BEAR", an objet d'art created with the theme of carved wooden bears, a traditional craft of Hokkaido, is used for the interior design of the Mitsui Garden Hotel Sapporo West (Chuo-ku, Sapporo City). Based on the concept of creating new values that interpret tradition in an innovative way, everyday wooden furniture such as chairs and tables are dismantled and precisely layered to create new contours.

City Redevelopment Projects

The Group aims to realize the principles of coexisting in harmony with society, linking diverse values, and achieving a sustainable society. Furthermore, our stance toward neighborhood creation encompasses the following three activity goals.

  • Integration of diverse functions and features by promoting mixed use (combining applications and functions) and integrating the tangible and intangible aspects of the Group's operations.
  • Creation of communities by connecting regions with the people who reside, gather in, or visit the area.
  • Working beyond the simple creation of neighborhoods to address, through town management, specific needs as neighborhoods mature with age year after year.

In office buildings and all other developments, we take into account access to public transport. With locations near transport hubs, we offer convenience and safety, and also promote environmentally friendly use of public transportation at retail facilities, hotels, and other places where many people gather, to contribute to the reduction of CO2 emissions. Moreover, in all development, we evaluate accessibility for people with disabilities, take measures within the scope stipulated by laws and regulations, and in some cases make additional efforts.
