Terrawell is a mineral-based architectural surface designed to improve indoor environments.
Developed through advanced mineral processing research in Japan, Terrawell's microporous structure helps adsorb VOCs — including benzene — from indoor air over time. It also moderates humidity, contributing to more stable and comfortable interior conditions. All performance claims are supported by independent test data available upon request.
Unlike conventional ceramic tiles, Terrawell is never fired — eliminating kiln emissions entirely and resulting in a fundamentally lower-carbon material.
As a specification-grade architectural material, Terrawell is available in custom sizes, finishes, and colors. It is suitable for interior wall surfaces and feature walls in residential, hospitality, healthcare, and commercial projects worldwide. Terrawell is intended for interior walls and covered exterior areas such as soffits. It is not intended for floors, or for areas subject to standing water or continuous wetting.
Terrawell's mineral surface is naturally matte with a quiet, architectural presence.
The mineral surface responds to changing light conditions throughout the day, revealing subtle variations in tone and texture.
Terrawell tiles can be composed into bespoke wall panels, tailored to the scale and vision of your project. Each panel is a unique expression of mineral craft.
Custom panel compositions available upon request. Contact us to discuss your project.
Terrawell is designed as a high-performance mineral building material with tested indoor air quality benefits.
Test reports available on request.
Watch how Terrawell hardens through carbonation, taking up CO₂ from the air.
All performance data tested by independent institutes in Japan. Data available upon request.
Terrawell hardens through carbonation and continues to take up CO₂ into the product body after manufacture. As stated in its EPD: "This product has a function to adsorb and fix CO2 within the product body after completion, but this absorption and fixation effect is not included in the calculation results." (SuMPO-EPD-2601-84-1, p.9)

Terrawell is developed with long-term environmental responsibility in mind — from material composition to end-of-life performance.
Made from natural mineral compounds with no organic binders.
A mineral composition with no organic binders. The EPD declares a service life of approximately 15 years based on the statutory useful life for building fixtures in Japan; actual service life depends on the installation environment.
Environmental Product Declaration issued under SuMPO, third-party verified by BOKEN Quality Evaluation Institute. Conforms to ISO 14025 and ISO 21930:2017. System boundary: product stage (A1–A3). Scope: PRO series only (S type not assessed). Valid until January 2031.
A product-specific, third-party verified Environmental Product Declaration (SuMPO-EPD-2601-84-1, ISO 14025 / ISO 21930:2017) is available for embodied carbon documentation. Independent VOC and odour test reports are available on request.
Terrawell accepts end-of-life materials from other industries and returns them as architectural surfaces — a material designed for circularity. Because Terrawell is never fired, materials can be reclaimed and reused, closing the loop on building material waste.
Three registered patents covering the proprietary non-fired mineral formulation. Patent No. 7545781, 7366378, 7366379 (Japan Patent Office)
Kano Corporation is committed to reducing greenhouse gas emissions by 42% by 2030, validated by the Science Based Targets initiative.
