Naoto Fukasawa designs limited-edition portable paper lamp
Naoto Fukasawa uses the simplicity of everyday paper as the starting point for SIWA A4 Light, a limited-edition portable lamp for SIWA, the washi-based brand developed by longtime manufacturer Onao. Limited to 100 units and releasing in late January 2026, the piece turns the familiar geometry of a standard A4 stack into an illuminated object, a play on material perception, scale, and the cultural intimacy of Japanese paper. ‘The appeal of a light object wrapped in paper is that the paper itself is the element,’ Fukasawa describes.

SIWA A4 Light: From Desktop Staple to Luminous Companion
Rather than treating paper as a diffuser or covering, product designer Naoto Fukasawa begins with the archetype of 500 sheets of A4 copy paper, then substitutes it with Siwa’s own Naolon, a strong, water-resistant washi-derived material. The form retains the proportions of a ream, transforming what is normally a quotidian desktop item into a luminous, monolithic block. In this translation, the stack becomes a vessel for light rather than ink, suggesting how subtle shifts in material can recast an everyday silhouette as a sculptural domestic object.
A dedicated paper bag accompanies the lamp and is designed specifically to hold and transport it. The gesture nods to the brand’s lineage in soft, foldable paper goods, while also positioning the light as something carried from room to room rather than fixed to a single spot. The lamp’s built-in LED offers up to five hours of illumination at full brightness, or roughly 170 hours at its lowest setting, extending its function as a portable, battery-powered companion. The SIWA A4 Light with bag is priced at ¥55,000 (tax included) and measures H55 × W210 × D297 millimeters, weighing 800 grams.
