"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,'"
"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."
Naoto Fukasawa's SIWA A4 Light reproduces the proportions of a 500-sheet A4 ream using Naolon, a strong, water-resistant washi-derived material. The design retains the everyday A4 stack silhouette and transforms the form into a luminous, monolithic block that emphasizes material perception and the cultural intimacy of Japanese paper. A dedicated paper bag is included to carry the lamp between rooms, reflecting the brand's lineage in soft, foldable paper goods. The built-in LED delivers up to five hours at full brightness or roughly 170 hours on its lowest setting. The limited edition of 100 units measures H55 × W210 × D297 mm, weighs 800 g, and is priced at ¥55,000 (tax included).
