Wood tiling work: a creation of complicated and three-dimensional shapes by arranging long and short rectangular wooden pieces. Its origin can be traced as far back as the mid-Edo era, when they were used as toys such as "chiegi" and "chieita". Japanese shrines, which are made without any nailing or metal pieces, are constructed using the same method. Imagination during the entire production process is necessary for "assembly". Then, when the individual processes of metallic molding, the production line and everyone involved in the process overlap with each other, "quality" shows itself for the first time.

-Everything is done to improve quality.

Metallic molding, which is responsible for nearly 40 processes and pressed at the speed of several hundred times a minute, can be considered a high-speed "production line" by itself. Human hands assemble each of the 500 to 1000 parts that make up a metallic mold. Zero defects in the finished products can only be achieved with total precision in the metallic molding, the production line and the people. Not 1 or 0.1 or even 0.001..
