How Japan has been sustainably producing wood since 700 years without cutting trees

Japan's 700-year legacy of sustainable wood production exemplifies harmony with nature. Through techniques like Daisugi, developed in the 14th century, they foster forests while harvesting timber. This tradition ensures a continuous supply of high-quality wood, preserving ecosystems for future generations and showcasing Japan's commitment to environmental stewardship.(Image:GreenQueen)

​Daisugi, an ancient Japanese forestry method, emerged in the 14th century in Kitayama due to sapling scarcity. Selective pruning of cedar trees ensured straight, knot-free lumbers. Originating from necessity, it evolved into a sustainable practice, embodying Japan's tradition of innovation in resource management for over seven centuries. In Daisugi, cedar trees are planted and pruned in a special manner to encourage the growth of straight, knot-free lumbers. This selective pruning involves hand-pruning the shoots every two years, leaving only the top boughs intact.(Image:GreenQueen)

Long Harvesting Cycle: The harvesting of daisugi trees takes approximately 20 years. During this time, the trees are carefully tended to ensure optimal growth and quality of the lumber. (Image:GreenQueen)

Daisugi was developed not only due to the scarcity of raw materials but also in response to architectural trends. In the 14th century, the popularity of sukiya-zukuri architecture, characterized by linear and stylized forms, increased the demand for high-quality wood. (Image: Instagram/unownedspaces)

Sukiya-zukuri, a term that translates to “built according to one’s taste,” is a style of Japanese architecture that emphasizes simplicity, natural beauty, and a harmonious blend with the surrounding environment. This architectural style extends to the furniture within, which is characterized by its understated elegance and functional design. Sukiya-zukuri furniture often features clean lines and a minimalistic approach, using natural materials like wood and bamboo to create pieces that are both beautiful and practical. The furniture is designed to complement the tatami floors and sliding doors commonly found in traditional Japanese interiors, and it often includes built-in elements like the tokonoma, an alcove for displaying art or flowers. The beauty of sukiya-zukuri furniture lies in its ability to create a serene and contemplative space, where each piece serves a purpose and contributes to the overall aesthetic of wabi-sabi, the appreciation of imperfection and transience.

Traditionally, this type of cedar was used for tokonoma alcoves in tea houses and as main pillars for displaying artistic items during the Muromachi period. Although its use in traditional alcoves is declining, this highly prized wood still finds applications in everything from chopsticks to furniture.

The wood produced through the daisugi technique possesses remarkable qualities. It is 140% more flexible than standard cedar, 200% denser and stronger, and exceptionally durable. (Image:GreenQueen)

Across the globe, various cultures have developed sustainable forestry practices akin to Japan’s Daisugi technique. For instance, in Europe, methods such as coppicing and pollarding have been used for centuries. Coppicing involves periodically cutting trees down to their base to promote new growth, while pollarding is similar but involves cutting higher up on the trunk. These practices allow for continuous harvest from the same trees, ensuring a sustainable supply of timber. In addition to these, agroforestry practices in tropical regions combine agriculture and forestry to create more diverse, productive, and sustainable land-use systems. These methods not only provide timber and other forest products but also contribute to biodiversity conservation, carbon sequestration, and soil health improvement.
