Appropriate Use of Water Resources
We recognize that water is both necessary for our business activities and an important resource for the local communities in which our business sites are located. Accordingly, we are addressing water risk and promoting the efficient use of water resources on a companywide basis.
The Environment Committee effectively manages water risk while conducting managerial supervision that ensures both companywide response to these risks and efficient water resource utilization.
Water usage management
In order to optimize water usage, we monitor, manage, and analyze water intake status of the entire organization. By repeatedly planning, implementing, evaluating, and improving water usage reduction plans, we aim to reduce environmental impact and comply with laws and regulations, thus contributing to the global environment and society.
Additionally, we monitor, manage, and analyze water usage across all our facilities, with a particular focus on large-scale network centers and data centers where air conditioning equipment consumes significant amounts of water. By closely monitoring these areas, we optimize their operation.
The goals and achievements for water usage are as follows.
| Items [Unit] | Results | Target | ||||
|---|---|---|---|---|---|---|
| FY2019 | FY2020 | FY2021 | FY2022 | FY2023 | ||
| Water consumption (Water withdrawal) [m³]*1 | 1,191,210 | 1,330,834 | 675,729 | 731,594 | 1,854,053 | 1,986,000 |

- [Notes]
-
- *1For offices that do not have individual meters, calculations are based on the area of the office and actual water consumption within the group.
- *The calculation method was changed in FY2021.
- *Coverage based on the sales ratio of each group company in FY2022 is 75.8%.
- *Coverage based on the sales ratio of each group company in FY2023 is 99.5%.
- *We have obtained third-party verification (limited assurance level in accordance with ISAE 3000).
- *As a long-term target until FY2030, we assume that the demand for water will increase due to business expansion, but we have set the same level of water consumption as the current level by striving for more efficient use, etc.

Major initiatives
Efficient use of water resources
At our headquarters building, “Tokyo Port City Takeshiba Office Tower,” we are implementing water-saving measures to reduce miscellaneous water usage by over 30%. Rainwater collected from the roof and other areas is gathered through roof drains and kitchen wastewater is collected, stored, sterilized, and reused for toilet flushing. Additionally, on each floor, we have installed water-saving devices such as flow restrictors on hot water supply facilities and sound simulators in toilets to reduce the frequency of flushing.
We promote water conservation by disseminating information about these initiatives to all employees through internal intranet and other channels, raising awareness across the organization.
Support for building new water supply systems in regions where maintenance of water infrastructure is difficult
We are collaborating with WOTA Corporation, with whom we have entered into a capital business partnership, to address the financial challenges in the water supply business. We are working on solving the issues in depopulated and island areas where maintaining water infrastructure is difficult. Utilizing WOTA Corporation's “Residential Connection System,” which enables 98% recycling of all domestic wastewater without connecting to existing water supply systems, we have been conducting pilot experiments in Toshima Village, Tokyo since June 2023. We are striving towards realizing a mechanism to supply water reliably in island areas.
Furthermore, we are also conducting sales of water circulation-type handwashing stands called “WOSH,” which enable water use even in the event of water supply disruption due to disasters, and portable water recycling systems called “WOTA BOX,” which provide bathing opportunities in evacuation centers.
