Visualizing the proportion of textile materials sourced for apparel: Aiming for 100% procurement of environmentally responsible materials

In December 2025, Ryohin Keikaku formulated the “Ryohin Keikaku Group Responsible Raw Material Sourcing Guiding Principles” and calculated the procurement ratios of textile materials used in apparel by type, as well as that of environmentally responsible materials that consider the impact on the global environment, animal welfare, and producers and local communities. We establish various policies and guidelines regarding raw material procurement with the aim of fostering a shared understanding across the entire supply chain regarding the Ryohin Keikaku Group’s material procurement goals. Going forward, we will further accelerate the procurement of environmentally responsible materials for key raw materials of textile and leather products and advance initiatives to transition to 100% procurement of environmentally responsible materials by the fiscal year ending August 2030.

Establishing raw material procurement guidelines to enhance transparency

The motivation behind this transparency initiative stems from the growing severity of environmental challenges such as climate change and deforestation. Textile materials are highly dependent on natural resources, and how they are procured is directly linked to corporate social responsibility.

Since its founding, Ryohin Keikaku has continued manufacturing based on three core principles: “selection of materials,” “streamlining of processes,” and “simplification of packaging.” We have promoted the use of environmentally responsible materials that have been evaluated and certified in accordance with the Ryohin Keikaku Group’s approach to policies on human rights, environment, and animal welfare. Since 2021, we have been strengthening our product development structure and expanding our production management bases from Japan and mainland China to Southeast Asia. To foster a shared understanding across the entire Group and accelerate the transition to environmentally responsible materials, we have clarified and disclosed the definitions in these guidelines. Furthermore, in addition to materials such as cotton, wool, and down—for which standards had previously been established—we have clearly defined our approach to environmentally responsible materials for virtually all materials, including leather and silk. We are striving to improve transparency by sharing the established guidelines with Group companies and production partners and encouraging compliance with these guidelines as well as the management of all information related to raw materials.

Seventy-five percent of textile materials used for apparel are plant- and animal-derived materials

We calculated the procurement volume of apparel designed in Japan for the fiscal year ending August 2025, which totaled 37,958 tons. Additionally, with the aim of visualizing our dependence on natural resources and our social impact, we calculated the procurement ratio of textile materials used in our apparel. The result revealed that 75% of the textile materials procured by Ryohin Keikaku were derived from plants or animals, while 25% were synthetic fibers. On the other hand, synthetic fibers account for approximately 70%*1 of global textile production. It clearly indicates that the company uses a greater proportion of plant- and animal-derived fibers in apparel production compared to global textile production.

For these calculations, we referred to Textile Exchange’s *2 “Fiber Uptake Calculations & Reporting Best Practices Guide” and “Fiber Conversion Methodology,” combining multiple data sources such as product quantities, material composition ratios, material weights including waste generated during the production process, and conversion factors from fabric to fiber.

The procurement ratio of environmentally responsible materials is also calculated

Ryohin Keikaku’s definition of environmentally responsible materials references the standards of the Sustainability Accounting Standards Board (SASB), aligns with industry standards, and is outlined in the Ryohin Keikaku Group Raw Material Sourcing Guidelines for Textile Products.” Based on these guidelines, we also calculate the procurement ratio of environmentally responsible materials among the primary raw materials used in apparel*3. In the fiscal year ending August 2025, the proportion reached 100% for our procured wool and down, and 99% for our procured cotton. On the other hand, for synthetic fibers, which account for 25% of our procurement volume, polyester stands at 77.8% and nylon at 44.1%; therefore, we must continue to focus on strengthening the procurement of environmentally responsible materials. We are working toward 100% procurement of environmentally responsible materials in collaboration with our production partners.

*3 Regarding the reporting period: From the fiscal year ending August 2021 through the fiscal year ending August 2024, the data covers textile materials used in products planned and sold during the spring/summer and fall/winter seasons of each year; starting from the fiscal year ending August 2025, the data is compiled in accordance with the fiscal year.

*4 As a result of minimizing the impact of COVID‑19 on our supply chain and ensuring a stable procurement of cotton, the use rate of organic cotton decreased. Since 2024, as the pandemic has subsided, we have been working to broaden our selection of cotton options that take both society and the environment into consideration—not limited to organic cotton—and to secure a stable supply of raw materials.

Future Outlook—Toward 100% by 2030

Currently, the procurement ratio of environmentally responsible materials in the apparel sector is approximately 80%. We will continue our efforts in collaboration with overseas group companies and production partners, aiming for 100% procurement of environmentally responsible materials in our primary raw materials. Furthermore, we will monitor the progress not only in apparel but also in household goods. We will deepen our stakeholders’ understanding of Ryohin Keikaku’s initiatives by disclosing the details of these initiatives in our integrated report, “MUJI REPORT,” and on our website and continuing quantitative management.
