Our Commitment to Using the Finest Materials
Wall MaterialFantastic Stucco


Red clam shells are the primary ingredient in fantastic stucco. Stucco has been known since mythological times, even appearing in the Book of Genesis in the Old Testament, in the account of the Tower of Babel. In Japan, early forms of stucco—composed almost entirely of lime—were used in ancient burial mounds (such as the murals in the Takamatsuzuka Tomb) and on the walls of many castles. Fantastic stucco also acts as a natural air purifier. This safe wall material is made entirely of natural components.
Another remarkable feature is its photothermal catalytic effect. Fantastic stucco reacts to temperature in both light and dark environments, and absorbs and breaks down airborne dust, odors, chemicals, and harmful substances. Because it responds to both light and heat, it is able to purify the air indefinitely, to continuously maintain a fresh, comfortable living environment.
Floor MaterialAcoustically Aged Wood
Udukuri Flooring


There are two primary methods for drying wood to influence its quality: natural drying and machine drying. While natural drying is undoubtedly better for the wood, it is time-consuming and often results in significant losses due to cracking and warping during the process—making it highly expensive as well. As a result, most wood is dried using machines.
Acoustically aged wood, however, is slowly and carefully dried in a special acoustic aging chamber exposed to classical music at a forest factory in Kagoshima Prefecture. The condition of the wood is carefully monitored in response to the weather and temperature each day, with meticulous adjustments made throughout the aging process. This approach to aging prevents cellular damage within the wood, preserves its natural oils and extracts, and instills it with moisture-retaining, water-preserving, and antibacterial properties.
Cedar is thought to enhance human immunity by promoting the production of immunoglobulin A, which helps protect the body from viruses, bacterial toxins, and other hazards.
Harnessing the natural strength of “wood that once lived” helps create a more comfortable environment.
