What Tokyo Big Sight Can Do for a Sustainable Society

In recent years, the demand for corporate social responsibility has greatly increased, such as the emphasis on ESG and involvement in the SDGs. In response, we formulated our CSR Policy to detail our fundamental principle of fulfilling social responsibilities primarily through our business activities. Based on this policy, we will engage in business activities while maintaining good relations with our stakeholders. Tokyo Big Sight contributes to achieving SDGs related to our business activities while clarifying our connections to these goals and raising awareness among our employees about them.

In addition, we regularly carry out various disaster drills and other activities assuming earthquakes and fires.

Role as a Temporary Accommodation Facility for Large-scale Disasters

Tokyo Big Sight and the three buildings we own are temporary accommodation facilities in the event of a large-scale disaster based on an agreement with the Tokyo Metropolitan Government. The facilities are stockpiled with drinking water, food, portable toilets, and generators for three days in preparation for disasters.

“Disaster Resilient " Waterfront City

Tokyo Waterfront City, where Tokyo Big Sight is located, has been developed with the concept of "disaster resilient city". There are no utility poles, and lifelines such as water and sewerage, electricity, gas, and information and communication are housed in utility tunnel to ensure safe supply.
In addition, the adjacent Tokyo Rinkai Regional Disaster Prevention Park is developed as a disaster prevention base facility for compiling disaster information and coordinating disaster emergency measures in the event of a large-scale disaster such as an earthquake directly under the Tokyo metropolitan area.

Providing Safe and Secure Facilities and Services

Development of a Safe and Secure Environment

At Tokyo Big Sight, we are developing the environment of our facilities with the aim of improving convenience for all users, including free Wi-Fi, barrier-free toilets, a prayer room, baby care rooms, and wheelchair rentals.

First Aid Training

We continuously conduct regular life-saving training for all employees to acquire knowledge and skills in first aid, and learn about cardiopulmonary resuscitation, foreign body removal, hemostasis, and AED handling. In recognition of our continued efforts, we received a Certificate of gratitude from the Tokyo Fire Department in September 2021.

Environment Conservation

District Heating and Cooling System

The cold and hot water used at Tokyo Big Sight is supplied from the Ariake south plant through a utility tunnel that runs through the waterfront area. At the plant, waste heat steam from local garbage disposal plant is used to prevent global warming, reduce CO₂, and save energy.

Implementing environmental measures

Tokyo Big Sight, as a large-scale business site, has submitted a plan to counteract global warming to the Tokyo Metropolitan Government's Bureau of Environment, in collaboration with the Tokyo Metropolitan Governments.
We have held three conferences on environmental measures, based on our promotion system to counteract global warming, and have confirmed the total CO2 emissions of our business.

Cooperation for “ZERO Emission Tokyo”

In September 2020, we cooperated with the Tokyo Metropolitan Government's "Zero Emission Tokyo" plan and provided 59,274 tons of CO₂ reduction credits generated under the Tokyo Cap & Trade System.

No Plastic Straws

In cooperation with shops and restaurants in Tokyo Big Sight, we have been conducting a campaign to abolish plastic straws since 2021. We are promoting replacement plastic straws with paper and biodegradable straws and the provision of drinks with no straws.

Promoting paperless practices

We promote paperless practices such as paperless meetings and reducing the use of faxes. We are also examining the use of PDFs for manuals and other printed materials for exhibitions we hold.
In addition, we introduce electronic internal application procedures for the purpose of improving operational efficiency.

Contributing to a Society in Harmony with Nature

Located in a seaside area with attractive landscapes and waterfront parks, Tokyo Big Sight manages approximately 40,000 square meters of green space, including gardens, green walls, and rooftop gardens.
The garden, which is the foreground of the venue, is designed with consideration for creating a continuous landscape with the nearby waterfront parks, and it serves as a resting post for wild birds.
We will continue to manage the garden appropriately with the aim of creating a comfortable space for visitors and workers and preserving the nature of the Ariake area.

CO₂ Reduction

Promoting the shift to LEDs

Tokyo Big Sight is shifting to LED lighting for our exhibition halls, reducing the amount of electricity consumed and CO2 emissions.

Promotion of ZEV (Projects in Cooperation with Tokyo Metropolitan Government)

We installed EV chargers in the basement parking area of the Conference Tower, encouraging the spread of zero emissions vehicles(5 chargers, 1 fast charger) We have also introduced ZEV as a company car.

Solar Thermal Utilization

Heat collectors installed on the rooftop of the conference tower collect the thermal energy of the sun and use it for suppling hot water to the kitchens of the on-site restaurants. We are working to reduce CO₂ emissions by efficiently utilizing solar heat, which is a renewable energy.

Maintaining and promoting greenery

Greenery is placed on walls and rooftops to improve urban scenery, clean the air, heighten the insulation of the buildings, and moderate the heat island phenomenon.

Promoting Use of Community-Shared Bicycles

A community-shared bicycle port of Koto-ward has been set up in the garden, and it is used by local people and visitors as an environmentally friendly transportation. It is also used as a means of transportation for employees.

The study committee for decarbonization in Tokyo Waterfront City

In September 2023, the Tokyo Waterfront City Association and Tokyo Metropolitan Government Bureau of Port and Harbor launched a special project called the "Decarbonization of Waterfront Area Development Study Committee" in order to accelerate decarbonization efforts in Tokyo waterfront city. We participate in the development of a "vision" for the decarbonization of the region in cooperation with local businesses and will work to promote the decarbonization of the region.
