Among several designs submitted by the designer, Incalmi selected the most complex, with the idea of challenging the material, rattan, a species of climbing palm tree widespread in Southeast Asia. The weaves characterize the entire surface of the object and remain visible even under the cathedral glass top, a type of glass with ancient origins and textural appearance. The result is a multi-material object made of rattan and glass, a coffee table but also a sculpture, which preserves roundness and lightness by combining contemporary taste with stylistic features of the tradition of different cultures. In fact, the name is inspired by Mount Koya, Japan, where craftsmen work precious rattan objects.

Formal research was then complemented by a thorough investigation of fiber coloration, through natural pigmentations and painting techniques capable of enhancing the material's characteristics. After several stages of testing with different types of earths, oxides and resins, the choice fell on Dragon's Blood, a resin made from the rattan itself that oxidizes and takes on a reddish hue-exactly the color the designer wished to achieve.
