The Ryohin Keikaku Group is aware of its responsibility to consume a large amount of water in the process from the production of raw materials through to manufacturing and commercialization, while remaining committed to reducing its impact on the global environment. As the effects of global population growth and climate change become more severe, inadequate management of water resources will further accelerate water risks in various regions, such as water shortages, floods and river overflows, and water pollution. The Group will promote sustainable use of water resources by reducing water withdrawal and consumption, while controlling, minimizing, and eliminating water pollution.

The Ryohin Keikaku Group respects and supports Goal 6 of the SDGs, "Ensure availability and sustainable management of water and sanitation for all," and will support stakeholders' access to WASH services by correctly identifying diverse water-related issues and addressing the challenge of inequality in water resources that should be equally enjoyed.

The Ryohin Keikaku Group is committed to preserving sustainable water resources in various areas such as within its company, supply chain, society, and local communities. Within its company, the Group identifies issues for each region where its stores and offices are located and promotes proactive and effective risk reduction activities. Throughout the Group's supply chain, the Group strengthen our business partnership with production partners who share its philosophy and work to reduce water usage in production processes, while also aiming to minimize the impact of its business activities on local communities and river basins.

Environmental management system is being managed and promoted in accordance with the Ryohin Keikaku Group's Environmental Policy.

Management System

We identify water resource risks and issues from three main perspectives: our own operations, supply chain, and society/community. We recognize that water usage in the raw material production and manufacturing process has a large impact on the environment and in local communities due to potential impacts on water sources and factory wastewater. The shortage of freshwater resources has become a concern due to various challenges posed by increasing populations, industrial development, global climate change, and water pollution. We recognize water scarcity as a risk for MUJI's services and are implementing various initiatives to address this issue, such as following an environmental management system.

Ryohin Keikaku assesses water risks associated with its supply chain operations in the relevant regions. We actively promote effective initiatives to address the water risks faced in the regions where Ryohin Keikaku and its production partners conduct business.
In the fiscal year ending August 2023, we conducted a survey of water risks at our own sites and those of our major suppliers using Aqueduct, a tool published by the World Resources Institute (WRI) that assesses global water risks based on latitude and longitude. We also responded to "CDP Water Security" for the first time and recognized the challenges we are facing. In the future, we will further assess the actual situation, focusing on supplier factories located in areas with high water risk, and link this to improvements.

At Ryohin Keikaku, we monitor the water usage at our headquarters and stores. The results of our monitoring are used to continually improve water conservation efforts and to measure their effectiveness. By promoting water conservation among our employees, we aim to build an environmentally conscious organization.

We are working with production partners to reduce the environmental impact by implementing water conservation techniques and technologies. We recycle production water at sewing factories, dye fabrics efficiently at dyeing factories to reduce water usage, and clean equipment using minimal water and recycle tank cooling water at cosmetics factories.

We have revamped our classic denim series for the 2022 fall/winter season with a focus on environmentally-friendly and long-lasting basic denim. In traditional denim production, the threads are dipped in indigo dye and pulled up repeatedly, undergoing a process called rope dyeing, which involves being exposed to air and oxidizing about 12 times to reach a deep blue color. Light-colored denim has typically required three times more water than regular indigo denim due to the need for wash processing to lighten the color after being dyed with indigo.
To reduce the water usage in our production process, we have re-evaluated our dyeing process for two new colors of denim. For "blue," we reduced the number of times the thread is dyed to four, while for "charcoal gray," we shortened the dyeing time. This has not only reduced the amount of dye used but also the water usage during wash processing. Additionally, we have also minimized the steps for traditional used and bleach processing for all denim series to make them more environmentally friendly.

Ryohin Keikaku has installed free water dispensers in selected MUJI stores that are open to anyone. Japan faces water supply reduction and insufficient budgets for updating water facilities due to population decrease and the popularity of bottled water. The stores now act as water supply points that promote tap water usage and reduce plastic waste. By taking this initiative, Ryohin Keikaku hopes to contribute to addressing the issues of water scarcity and sustainability.
