UPDATER Co., Ltd. launched the latest version of its textile and apparel industry service “TADORi CHAiN Powered by Coral” on September 4.
TADORi CHAiN is a service that records a product’s history—from production through repair, reuse and material recovery—on a blockchain that is extremely difficult to tamper with, using a QR code or similar marker attached to the product. This history can be verified via smartphone through issued and managed certificates. The service began as a pilot at the YOKE Aoyama store in October 2024, and following trials with multiple brands, has now reached this official release.
The service has four key features:
- It seamlessly records and manages information within a single system, spanning from the production stage (raw materials, manufacturing) through the post-sale stage (repair, reuse, recycling).
- Its authenticity verification mechanism only validates when three elements align: the “current rightful owner,” the “issuing brand,” and the “passport linked to the product.” Since only the legitimate owner can issue a QR code with unique specifications each time, this deters unauthorized resale through certificate duplication or impersonation.
- It includes a function to calculate and visualize greenhouse gas (GHG) emissions (including Scope 3) at the product or lot level, in line with international standards such as the GHG Protocol Product Standard. Users bear the license fees for the emission factors required for calculation and disclosure.
- It includes a function to register and manage in bulk the product information required for the Digital Product Passport (DPP), which is being rolled out in Europe. Since the specific DPP requirements for the textile and apparel sector will be finalized through delegated acts to be adopted under the Ecodesign for Sustainable Products Regulation (ESPR), the item design as of August 2026 is based on preparatory studies and other materials published by the European Commission.
Companies with implementation and pilot track records include apparel brands with overseas exports and supplier companies with international transactions, such as YOKE, ARCH&LINE, BLINDMAN TOGS, and Sustainable Mongol.
The company has coined the term “circular traceability” for its initiative of digitally recording and certifying information such as where and how a product was made and used, whether it is authentic, and its environmental footprint, in order to support the circulation of goods. TADORi CHAiN represents the first service in this initiative.
This initiative comes against the backdrop of a European trend, under the Ecodesign for Sustainable Products Regulation (ESPR), toward requiring phased information disclosure via Digital Product Passports (DPPs) for target products including textiles and apparel. This is a system for recording and disclosing data such as raw materials, manufacturing processes and environmental impact, with the specific requirements for the textile and apparel sector expected to be finalized through delegated acts yet to be adopted.
