Upcycled train strap handles form WA lamp by Akasaki & Vanhuyse
WA is a table lamp designed by Akasaki & Vanhuyse, produced from reused train components of the Tokyu Den-en-toshi Line 8500 series, which was retired in January 2023. Around 1,400 resin strap handles were collected, cleaned, and repurposed into a limited edition of 150 lamps, with the project emphasizing both reuse and sustainable production methods.
The strap handles were chosen for their circular form and availability in large numbers, making them suitable for upcycling. Each piece was inspected and graded based on imperfections, then sandblasted to remove the glossy coating and produce a matte finish. Surface marks such as scratches and dents remain visible, highlighting the material’s previous function and history. The lampshade is composed of nine stacked resin rings, arranged with small gaps to allow light to filter through softly. Mirrored stainless steel legs hold the structure together using custom bolts, their curved shape referencing the original strap form. A transparent power cord reduces visual interference, making the lamp adaptable for a variety of settings, including offices, stations, or domestic interiors.

WA table lamp emphasizes reuse, durability, and local production
The project by design studio Akasaki & Vanhuyse was developed with a strong focus on minimizing waste and ensuring longevity. The decision to reuse existing components reduced the need for additional processing, while stainless steel elements provide durability and resistance to rust. The design allows for easy disassembly, ensuring that materials can be separated and recycled at the end of the lamp’s life. Packaging was developed with the same approach, using recyclable aluminium vapor-coated paper instead of PET film, with manuals printed on recycled paper. Production was carried out locally in Tokyo, where the train line operated, reducing transport requirements and associated emissions.
WA demonstrates how upcycled components can be transformed into a functional and durable design object. By reusing resin strap handles from retired train carriages, the lamp connects material history with new utility, offering an alternative approach to production that combines reuse, local manufacturing, and sustainable design principles.
