"Discover the perfect harmony of craftsmanship and design with traditional Japanese woodworking techniques."
Pure connection
Imagine an old Japanese workshop, where the scent of fresh wood fills the air and the sun shines through paper screens. A craftsman leans intently over a piece of wood, his hands moving with calm precision. Without nails or glue, he creates a connection that fits so perfectly, it seems as though the two pieces of wood were made for each other. This is the art of the mortise and tenon joint, a technique that has been used for thousands of years.

An ancient technique
The mortise and tenon joint is an ancient woodworking technique that has been used for thousands of years in various cultures. This ingenious method, where a pin is perfectly placed into a corresponding hole, creates a strong and durable connection without the use of glue, nails, or screws.
The origin of this technique dates back to ancient Egypt, where it was used in furniture and construction. In Asia, particularly in Japan and China, the technique was refined into an art form. Japanese craftsmen used complex variations of the mortise and tenon joint to build temples, furniture, and other structures that effortlessly withstand the test of time. This technique symbolizes craftsmanship, precision, and harmony between functionality and aesthetics.

From Houses, Temples to Bridges
When we zoom in further on Japanese culture, it is generally known for its refinement and precision, which stem from pure attention and love for the act itself, the craftsmanship, the process, and not the final result. This way of life originates from Zen Buddhism: "It's not about achieving a specific goal, but about being fully aware of what you are doing." Ironically, this way of life does result in beautiful, almost superhuman craftsmanship, as seen in woodworking, for example.
The mortise and tenon joint appears in Japan in various constructions, including houses, temple complexes, and bridges.

Japanese construction techniques not only provide stunning aesthetics but also ensure a very solid structure. By using techniques such as the mortise and tenon joint, the distribution of pressure is naturally and evenly spread.

Traditional Craftmanship with a Modern Twist
The brand Ginza Lines® continues the tradition of ancient woodworking techniques in its contemporary exclusive oak roomdividers. The mortise and tenon joint is applied in every roomdivider by Ginza Lines. This technique seamlessly connects hand-crafted solid oak slats, creating a unity of abstract lines.
This joint also symbolizes the inherent function of the roomdivider, namely the connection of spaces.
In addition to its functional and durable role, the mortise and tenon joint creates an elegant aesthetic that manifests in precision, refinement, and subtlety. As the oak slats interlock seamlessly, a beautiful 3D effect emerges in every roomdivider.

Craftmanship vs Machine
Many roomdividers available on the market are mass-produced using a CNC machine. In the image below, the difference is clearly visible between a standard CNC-machine-produced room divider and a handmade roomdivider by Ginza Lines using the mortise and tenon joint.
