Six Materials
Duco creates products using six foundational urushi‑based materials, while also advancing new material development through technical collaboration.
By combining natural urushi with a wider range of contemporary substrates, we generate next‑generation materials that evolve with the needs of our time.
Historically, urushi has been applied to ceramics, iron, wood, textiles, paper, and leather—transforming the character and performance of each substrate.
We carry this adaptive potential into modern material development, identifying the textures and functions required amid shifting global conditions and supply environments.
Together with our partners, we co‑create materials that look toward the future.

Titan Maki‑eTitanium × Maki‑e
Titan Maki‑e uses titanium powder and granules, applied onto lacquered designs where urushi serves as the adhesive. This new approach brings color expression directly to the titanium particles, creating a distinctive aged‑metal character not found in traditional maki‑e. The result is a material with an art‑like presence that expands the expressive possibilities of urushi.
"Urushi Veil Sakura" Rhus Project - Urushi Film Cherry Blossom Pattern

Urushi Film The Thinnest New Urushi Material — Silver Leaf × Natural Urushi
The Thinnest New Urushi Material — Silver Leaf × Natural Urushi Developed from the traditional datsukanshitsu (dry‑lacquer removal) technique, this urushi‑and‑silver‑leaf film is the thinnest material in our urushi lineup. It can be freely cut with scissors, offering exceptional flexibility for design applications. Each sheet is delivered in vacuum‑sealed packaging to ensure optimal quality.
"Weeping Cherry Blossom" Optical Glass, Rhus Project

Glass Maki‑eGlass/Optical Lens × Traditional Maki‑e
Glass Maki‑e applies traditional maki‑e techniques onto glass or optical lenses. Beyond flat panels, the technique can be used on thick three‑dimensional forms—such as cylinders and rectangular pillars—creating a unique sense of depth and perspective within the glass. By incorporating the three distance perspectives—Heien (level distance), Shin’en (deep distance), and Kōen (high distance)—the design actively utilizes the reflections within the glass, producing a distinctive world that shifts in expression as the viewer’s perspective changes.
Natural Pattern: Retsu Pattern

Natural PatternGlass/Acrylic × Natural Urushi
The organic motifs formed by the transparency of glass combined with natural urushi create a powerful, distinctive presence. This material can be applied across a wide range of fields, from interior surfaces and furniture to art pieces and accessories.

Duco’s six proprietary materials
Natural Pattern, Acry‑U‑lil, Titan Urushi, Titan Maki‑e, Urushi Film, and Glass Maki‑e form an unparalleled material vocabulary exclusive to Duco.
Individually engineered to meet precise functional, tactile, and durability demands, each material bridges traditional urushi craftsmanship with advanced contemporary techniques.
They retain the profound optical depth and richness of urushi while introducing a refined modernity and forward‑looking design sensibility.
Even in mass production, every piece manifests a singular expression—affirming the inherent uniqueness of Duco’s material innovation.
01Interior Decorative Production (Architecture & Spatial Art)
Duco’s materials demonstrate a distinctive presence in architectural environments, made possible through our core technologies.
Combining the depth and luminous quality of natural urushi with the strength and stability of contemporary materials, our finishes are selected for entrances, lounges, and shared spaces in high‑end residences and commercial buildings.
In collaboration with artists and designers, they serve as refined surface materials suited for premium spatial design.
- Walls and signage of corporate entrance
- Decorative elements in luxury condominium common areas
- Art panels for hotels and residences
- Custom interior materials developed with architectural design firms
The way urushi responds to light—shifting subtly with the environment—creates a serene yet striking spatial experience.
Designing from Concept to Narrative
Our materials open the door to stories rooted in natural substances, craftsmanship, culture, tradition, and human sensibility. Rather than simply manufacturing objects, we collaborate to define why a product embodies a particular material or technique. From original corporate gifts and retail items to sculptural objects for interior spaces, we design expressions tailored to each purpose. Grounded in urushi craftsmanship, we consider the full context in which each piece will be experienced—its setting, its role, and the brand narrative it supports—creating value that is truly one‑of‑a‑kind.
