Medical Wear Brand “sukui” Utilizing DPP
The DPP system introduced in this feature is implemented in sukui, a medical wear brand planned, produced, and sold by WORKING HASEGAWA Co., Ltd.
Designed for healthcare settings with a high level of public responsibility, sukui is recognized for its pursuit of usability and comfort while achieving a well-balanced design that harmonizes with environmental considerations.
In both the production and repair processes of sukui products, WORKING HASEGAWA Co., Ltd. has adopted a blockchain-based DPP infrastructure jointly developed and implemented with Chaintope.
Proactively Building a DPP Infrastructure in Anticipation of Regulation
The Digital Product Passport (DPP) is a framework scheduled to be institutionalized in the European Union from 2027 onward. It aims to centrally manage and disclose environmental information throughout a product’s entire lifecycle—from manufacturing and use to repair and disposal.
Although regulatory requirements and specifications have not yet been finalized in Japan, WORKING HASEGAWA Co., Ltd. has proactively developed its own DPP infrastructure in anticipation of future compliance with international standards.
Blockchain-Based Environmental Transparency Across the Supply Chain
This system leverages Tapyrus, a blockchain platform provided by Chaintope, to visualize CO₂ emissions and absorption based on Life Cycle Assessment (LCA) methodologies. In addition, it records and displays a wide range of environmental data across the supply chain, including raw material sourcing regions, suppliers, and energy consumption.
The platform supports three languages—Japanese, English, and Chinese— enabling internationally transparent and reliable information disclosure.
Japan’s First DPP Implementation in the Medical Wear Sector
This initiative represents Japan’s first implementation of a Digital Product Passport in the medical wear sector, presenting a new benchmark for next-generation uniforms that contribute to the realization of a circular economy.
We will continue to advance initiatives that contribute to both healthcare environments and the global environment through the integration of technology and manufacturing.
