Water conservation measures

Water management plan

Tokyu Land Corporation formulates water management plans for all facilities it operates and manages. After assessing the results against the water supply plan for the previous fiscal year, which is the target, we are working to reduce water consumption by introducing water-saving equipment in toilets and showers and encouraging users to save water. We also recycle used tap water whenever possible. There are 24 facilities that use gray water, rainwater, etc. to reduce the amount of clean water used. (As of December 2023)

Tokyo Port City Takeshiba uses gray water for toilet flushing. The gray water is supplied from the facility's kitchen drainage, rainwater, and air conditioning drain water, and can be replenished from the heat storage tank in case of emergency. Kitchen wastewater is purified by a gray water desalination system (membrane treatment + bioreactor system) via a grease removal system installed in a restaurant in the building, while rainwater and air conditioning drain water are purified by a filtration system (pressure type rapid filtration system + activated carbon adsorption system) and used respectively.

Initiatives in water-scarce regions

Engagement, water withdrawal, etc.

Tokyu Land Corporation develops and operates hotels, golf courses, villas, etc., but in areas where water resources are scarce, we are discussing water use with local governments. Tokyu Resort Town Tateshina, which was developed in Nagano Prefecture, is engaged in a water supply business for 23.5 km² in consultation with Chino City since 1977. During the operation period, we have continuous discussions, engage in water supply population and water supply amount every 10 years and supply water based on the decided plan.

Business activities in water-scarce regions

The Republic of Palau is chronically suffering from a shortage of water. At Palau Pacific Resort, we have our own water supply facilities from the time of opening, we operate the hotel with our own drinking water, and we strive to conserve water resources in the Republic of Palau by thorough water conservation.

Facilities in Water-Stressed Regions

For our group's operational sites, an annual assessment of global water stress is conducted using the "Overall Risk" and "Baseline Water Stress" indicators from WRI Aqueduct. If an area is classified as "High" or above in both "Overall Risk" and "Baseline Water Stress," we determine it to have high water stress As a result, as of March 2023, there are no regions classified as "high" or higher.
Regarding Palau, one of our operational sites, it is excluded from WRI Aqueduct's scope. Therefore, we evaluate global water stress using the World Wide Fund for Nature (WWF) Water Risk Filter.
Additionally, for Indonesia, another operational site, the company operates only in facilities leased as tenants and does not engage in direct water extraction.

Works with others

Works with others to reduce water use

Tokyu Fudosan Holdings is a regular member of the Real Estate Association, and in 2013 we formulated the "Real Estate Business Environment Implementation Plan" at the Environment Committee. Among them, as concrete actions to reduce the amount of water used, we aim to use water-saving appliances such as toilets and showers, automatic faucets, automatic cleaning devices, rainwater, etc. In addition, we are working to further raise environmental awareness by sharing information on excellent initiatives, and we are working to save water in collaboration with not only real estate companies but also construction companies and other industry companies as a whole.

Collaboration with other companies operating at same sites such as making use of water waste streams as inputs (industrial ecology)

Collaboration with other companies

At Tokyo Port City Takeshiba, we are collaborating with companies(tenants) to reuse wastewater. Kitchen wastewater, etc., from tenants in the facility is purified by a gray water generator via the grease removal equipment installed in the store, and reused for flushing toilets.

Collaboration with local governments

At Tokyu Plaza Totsuka, industrial water supplied by Yokohama City is used for cleaning toilets. This will prevent ground subsidence due to excessive pumping of groundwater, and will work in collaboration with local governments, such as energy reduction by subsidence treatment and use of raw water without performing chemical treatment or filtration treatment processes such as water supply. We are promoting industrial ecology.

Costs associated with water-related risks

The cost of water-related risks for TOKYU LAND CORPORATION in fiscal 2022 was 44 million yen.

Third-party Independent Verification

The Tokyu Fudosan Holdings Group receives independent verification of its environmental data from a third-party in order to ensure the reliability of this information.
For water usage, data on water consumption (tap water, sewage, and grey water) are included in the scope of verification.
