Circular Design

Approach and Policies

Group Policy (Environment)

Under the Group Policy and recognizing that the depletion of natural resources associated with urban development is a major social issue, we will contribute to realize a decarbonized society and circular economy by reducing waste discharge and by providing urban development and services that promote longer building lifespans, the reuse of materials, and the sharing of spaces.

Reduction and Appropriate Management of Waste Discharge

The Group plans to reduce waste discharge and increase the recycling rate throughout the life cycles of products and services. We appropriately manage waste from design to construction, operation, and demolition of buildings to reduce the environmental impact of waste during real estate development.

Restoring Condominiums

The Group is working to restore old condominiums into homes with new value. We expanded PROUD Uehara Forest, which was established more than 30 years ago, by utilizing its excess floor space with the latest technologies while improving its livability. As a result, it was certified in 2019 as excellent long-term housing for the first time as an old condominium built by a private developer. It was also certified as having a service life of 65 years by a third-party evaluation agency.

Reduction and Reuse of Waste

The NOHGA Hotel, operated by the Group, is working to reduce and reuse waste through such efforts as reducing the use of plastics by eliminating single-use toiletries and using biodegradable bamboo straws derived from plant fibers. It is also using name plates and handkerchiefs made from reused scraps of leather and Japanese clothing.

Pilot Demonstration of Centralized PET Bottle Collection for a Circular Economy

As part of our efforts to achieve a circular economy and reduce CO2 emissions, we conducted a pilot demonstration of the centralized collection of PET bottles and verified their separation and disposal status at 19 properties (four offices and 15 condominiums) managed by the Nomura Real Estate Group in cooperation with Suntory Beverage & Food Limited, Shirai Group Co., Ltd., and Shutoken Environmental Beautification Center, Co., Ltd. Using the pilot results, we will further reduce CO2 emissions, improve collection efficiency, and promote activities to raise awareness of bottle separation.

Overview of Pilot and Verification

Background Although Japan’s PET bottle collection rate is high, most of the PET plastic recycled from these bottles is of low quality, so in actual PET bottle production, new materials must be input in addition to recycled materials.
Purpose There are high expectations for horizontal recycling in which used PET bottles are used as raw materials to manufacture PET bottles of the same quality. One issue to be addressed in realizing this initiative is verifying reasonable collection costs and sufficiently reducing CO2 emissions during transport.
Results and future prospects Centralized collection improves efficiency and contributes to reducing CO2 emissions from collection vehicles. On the other hand, we confirmed that PET bottles collected from offices had a high rate of foreign matter contamination, leading to a decline in recycling quality. In the future, we will consider ways to reduce the rate of foreign matter contamination.

Effective Utilization of Water Resources

The Group intends to reduce water consumption throughout the life cycles of products and services.


Introduction of Water-saving Devices Upon New Construction and When Performing Renovations

Water and hot water saving devices have been made standard equipment when developing housing, office buildings, retail facilities, logistics facilities, and other structures in accordance with its design and construction standards and quality manuals. In addition, fixtures are systematically replaced with water-saving devices when performing renovations.

Details of design and construction standards and quality manuals can be found here.

Water Risk Assessment

The Group conducts water risk assessments on its properties using Aqueduct, a tool designed for that purpose. As a result, all properties built by the Group in fiscal 2022 (85 buildings in total: 71 in the residential sector and 14 in the urban development sector) were found to be located in “Low-medium” water risk areas and outside of “Medium-high” and higher water risk areas. Therefore, no water was taken from areas designated as “High” or “Extremely high” by the properties built in fiscal 2022. We will continue to periodically monitor the water risk.

Collaborating with External Partners to Reduce Water Use

The Group is a formal member of the Environmental Committee in the Real Estate Companies Association of Japan. In 2013, this committee formulated the Real Estate Industry Environmental Action Plan, which includes specific initiatives such as introducing highly effective water-saving fixtures and automatic faucets and flushing systems. It is aiming for the entire industry to work together in an effort to reduce water usage.

Initiatives for Longer Life and Increased Durability

The Group Intends to extend the lifespans of its buildings by using highly durable materials with long lifespans and implementing appropriate management and repair plans.


Measures to Lengthen Cycles for Large-Scale Repair Work

In order to reduce the economic and psychological burdens on condominium residents and management associations and to reliably carry out large-scale repair plans, the Group offers products and services intended to lengthen large-scale repair work cycles.


Measures at Completed Condominiums

Due to the aging of the population and the increase in vacant dwelling units, about 35% of condominiums are unable to accumulate sufficient reserves for repairs as scheduled (source: data by Ministry of Land, Infrastructure, Transport and Tourism). The re:Premium repair and maintenance service offered by the Group is designed to extend the cycle for large-scale repair work for PROUD condominiums that have already been completed. The service can extend the typical 12-year cycle for large-scale repair work to 16 to 18 years and result in ultra-long-term improvement plans of up to 60 years after the completion of construction. It extends the lifespans of buildings and reduces demolition waste. It also reduces the psychological and economic burdens on customers by substantially cutting lifecycle costs. For these reasons, the Group is striving to expand the scope of properties that adopt the re:Premium service.
In fiscal 2020, drainage pipe repair work in the common use areas for replacing older pipes made of different materials with plastic pipes all at once to improve performance and reduce lifecycle costs for the Coop Nomura Higashi Rokugo, which is under Group management, was certified as a model project for extending the life of condominium stock with the support of the Ministry of Land, Infrastructure, Transport and Tourism.

Measures at Newly-Constructed Condominiums

In fiscal 2018, the Group launched the Attractive30 service, which seeks to increase the lifespans and durability of newly-constructed condominiums. Under this initiative, the Group will promote the adoption of highly durable materials and construction techniques and the introduction of the re:Premium service to realize an extension of the cycle for large-scale repair work.

Collaboration with Suppliers

The Group is aiming for the appropriate management of resource use in the entire supply chain. Accordingly, the Group established the Nomura Real Estate Group Procurement Guidelines and is working with all of its suppliers to reduce its environmental load.

Nomura Real Estate Group Procurement Guidelines (excerpts)

Reduce energy use and greenhouse gas emissions through circular design to reduce waste by extending the life cycles of goods, products, and services. Strive to efficiently use natural resources, including water, and to optimize and reduce usage.
Appropriately manage hazardous chemicals and reduce the amounts used and reduce emissions of pollutants that have adverse effects on the environment and the human body.
Reduce and appropriately manage waste.
When procuring raw materials, take into consideration the conservation of biodiversity and sustainable use of resources. In particular, when procuring wood and wood products, take due care not to use illegal logged timber, and endeavor to use wood that has been produced by sustainable methods, such as recycled wood and certified wood.
