Japan’s Ancient Building Technique Joins Wood Without Glue or Nails

The ancient Japanese woodworking technique known as kumiko, which originated in the Asuka period (538 to 710 C.E.), involves precisely cutting thin wood slats to interlock into repeating geometric patterns. Initially used for screens and inlaid furniture panels, kumiko has evolved into a celebrated art form with its own distinct designs. This art will be featured at the 43rd annual Smithsonian Craft Show in Washington, D.C., held from April 24 to 27. The show will present the work of 120 American artists across various disciplines, with selections based on originality, artistic conception, beauty, and quality. Among the featured artists is David Gootnick, a D.C.-based kumiko craftsman. Gootnick utilizes Alaskan yellow cedar, transforming a five-foot-long plank into intricate, often less than two-millimeter-thick pieces. He emphasizes the importance of consistent wood thickness and precise angle cuts for the lattice-like designs. Gootnick, a lifelong woodworker, discovered kumiko ten years ago through online practitioners, including Australian expert Des King. He began by incorporating kumiko into cabinetry panels before creating self-contained wall art. While adhering to traditional Japanese motifs like hexagons and equilateral triangles, Gootnick adds contemporary elements such as darker redheart or Osage woods for color contrast and incorporates colorful cloth backings. He also introduces his own variations, including rosettes and lanterns, reminiscent of mission furniture. Although traditional kumiko relies solely on pressure from precisely cut angles, Gootnick uses a small dot of glue for enhanced longevity, ensuring his pieces endure for centuries. Another artisan showcasing kumiko at the Craft Show is Michael Jury from Springfield, Virginia. Jury, primarily known for his handmade Shaker- and Danish-inspired furniture, integrates traditional kumiko patterns into his cabinets and tables. He crafts basswood into small components to form the 'asa-no-ha' (hemp leaf) pattern. Jury has also used kumiko panels as sliding doors for a sideboard, backed with black momigami (kneaded paper), a piece that has received critical acclaim, including “best in show” awards at several exhibits. Gootnick notes his continuous improvement in the kumiko process, observing that a piece that once took him a month to complete can now be finished in two weeks, with a cleaner and more precise result. This evolution reflects a dedication to achieving closer to perfection in his craft. #Kumiko #JapaneseWoodworking #GeometricPatterns #SmithsonianCraftShow #DavidGootnick #WoodArt #Craftsmanship #Artisan #HomeDecor

Contemporary furniture designer Robby Cuthbert crafts sculptural pieces that merge architectural principles with organic forms, using the concept of tensegrity. His creations, including coffee tables, lamps, shelves, and chairs, are meticulously constructed from wood and steel cables, entirely eschewing traditional fasteners like glue, screws, and nails. This innovative approach results in furniture that appears light, airy, and modern. Tensegrity, a term coined by renowned American architect Buckminster Fuller, describes structures that achieve stability through a balanced distribution of tension. A prime example is the geodesic dome, which, despite its delicate appearance, derives its strength from the tension between its interconnected components. Cuthbert applies this very theory to his furniture, engineering each piece to perfection. The tension within the steel cables or the cantilevered design, anchored to a single point, provides the necessary structural integrity. Cuthbert's work transcends mere functionality, functioning equally as elegant artwork. His background in studio art, coupled with a keen interest in architecture and sculpture, profoundly influences his design philosophy. He explains that he aims to generate architectural and organic forms, often incorporating fantastical or whimsical elements, to explore the role of tension in storing and releasing energy. He uses wood and wire as his primary materials to suggest a state of pent-up energy, held in equilibrium by opposing forces. Each piece maintains potential energy, implying a transformative shift if that energy were to be released. The absence of visible fasteners like nails, screws, and glue is a defining characteristic of his work, highlighting the ingenuity of tensegrity. This method allows for unique aesthetics where components seem to float or defy gravity, creating a sense of wonder and visual intrigue. The design process involves a deep understanding of structural mechanics and material properties, ensuring that the inherent tension within the materials contributes to the overall stability and form of the furniture. His collection, which includes diverse items from lounge chairs to wine racks, showcases the versatility of tensegrity in furniture design. Each item is not just a piece of furniture but a demonstration of complex engineering principles applied artistically. Cuthbert's designs encourage viewers to appreciate the unseen forces at play, celebrating the elegance of structural balance. The visual effect is one of minimalist beauty, where the materials are presented in their most essential and dynamic forms. #contemporaryFurnitureDesign #tensegrity #tensegrityFurnitureDesign #modernFurnitureDesign #RobbyCuthbert #architecturalPrinciples #sculpturalFurniture #designInnovation

The traditional Japanese woodworking technique of using *kanna* (handplanes and spokeshaves) offers an alternative to sandpaper for achieving incredibly smooth, glass-like finishes on wooden furniture. Unlike Western planes made with cast-iron or bronze bodies, *kanna* are constructed with wooden bodies that support an iron cutter. This method is employed by craftspeople like Toshio Tokunaga and his apprentices, who deliberately avoid sandpaper in their furniture production. They contend that sandpaper abrades the natural grain of wood, creating an artificial smoothness that diminishes the wood's inherent characteristics. In contrast, the *kanna* precisely shaves off successive layers of wood, thereby preserving its natural appearance. A key distinction lies in the action of the tools: *kanna* blades cut, while sandpaper tears. This fundamental difference results in a superior finish from *kanna*, perceptible both microscopically and to the touch. Tokunaga, a master craftsman, not only utilizes *kanna* but also designs and fabricates his own tools, ranging from those for initial roughing work to specialized planes for fine, final shavings. His extensive collection of *kanna* encompasses a wide array of shapes, enabling him to expertly handle various contours—flat, concave, and convex—required in his furniture designs. The *kanna* technique produces a distinct finish that many consider to be more authentic and natural than finishes achieved with sandpaper. While the final appearance can be incredibly smooth, the discussion within the woodworking community often revolves around whether a true 'glass-like' gleam is achieved solely through planing or if it requires additional elements like natural oils from handling or even a minimal finish. Some experts suggest that while *kanna* provides an exceptionally smooth surface, a highly reflective, glossy finish might also be influenced by factors such as burnishing or the presence of oils, similar to how western woodworking scrapers, when properly sharpened, can achieve comparable results by shaving thin layers. The efficacy of the *kanna* finish relies heavily on the meticulous maintenance of the blades, which are regularly sharpened on waterstones by apprentices. The irons themselves are not mass-produced but are custom-made locally, highlighting the specialized nature of these tools. This commitment to traditional methods and bespoke tooling underscores a philosophy that prioritizes the natural beauty and integrity of the wood, offering an enduring finish that respects the material's innate qualities. #woodworking #JapaneseCraftsmanship #Kanna #woodFinish #furnitureDesign #handTools #traditionalTechniques #artisan

John Webster, a former commercial oil and gas diver, has transitioned into a timber craftsman specializing in Yakisugi, an ancient Japanese method of charring timber. This technique, also known as 'burnt cedar,' offers a durable, low-maintenance, and aesthetically pleasing alternative to traditional stained timber, particularly for achieving the popular black timber house look. Unlike staining, which can be harsh on wood, Yakisugi enhances the timber's natural properties, making it more resistant to insects, UV radiation, and water due to its hydrophobic qualities. Webster's journey into Yakisugi was born out of extensive experimentation. He spent approximately two and a half years in his garage developing the precise method for charring wood, a process that initially led to a serious incident involving smoke inhalation and a stay in Intensive Care. Following this, he implemented a smoke extractor system to safely continue his work. His dedication allowed him to master the technique, enabling him to produce charred timber in commercial volumes. Traditionally, Yakisugi utilizes Japanese cedar. However, Webster has found that thermally modified radiata pine from the New Zealand company Abodo Wood serves as an effective and sustainable local alternative. This adaptation makes the ancient Japanese technique more accessible and environmentally conscious in his region. Prior to his career as a timber craftsman, John Webster spent 12 years working as a commercial oil and gas diver. His work involved extended periods in confined spaces with limited human interaction, leading to unique psychological challenges. An accident that occurred at a depth of 220 meters resulted in PTSD symptoms, which he later recognized when a seemingly innocuous act like putting on his motorcycle helmet triggered a panic attack. Through resilience and recovery, Webster has overcome these challenges and can now comfortably engage in activities like scuba diving and riding his motorbike. This article highlights John Webster's remarkable career change from a high-pressure, hazardous profession to a specialized craft, emphasizing his innovative approach to traditional timber treatment and his ability to overcome personal adversity. His work with Yakisugi not only provides a sustainable and durable building material but also introduces an ancient, effective technique to a modern context. #Yakisugi #TimberCraftsmanship #JapaneseTechnique #SustainableBuilding #CareerChange #WoodTreatment #Entrepreneurship #PTSDRecovery

Traditional Japanese rural homes, known as kominka, are facing widespread demolition in Japan due to urbanization, population decline, and maintenance challenges. These timber-framed structures, historically serving as single-family dwellings for multiple generations, are increasingly being abandoned or torn down to make way for new construction, as their cultural and historical significance often goes unrecognized in their native land. A survey by Japan’s Ministry of Internal Affairs and Communications indicated a 13% decrease in kominka between 2008 and 2013, with experts estimating only about 1.25 million remaining. The decline is further fueled by issues such as the lack of central heating and adequate insulation for harsh winters, concerns about earthquake resistance under modern building codes, and significant costs associated with repairing water or insect damage. Additionally, a diminishing number of carpenters possess the traditional skills required to work on these homes, and financial incentives for renovation are often difficult to access. This situation leads many owners to prefer demolition and new construction over preservation. In response to this loss, organizations such as the Kominka Collective, with offices in Japan and the U.S., Toda Komuten, and the Japan Kominka Association are actively working to salvage and repurpose these structures. Their efforts are guided by the Japanese concept of "mottainai," which emphasizes avoiding waste. These groups identify abandoned or dilapidated kominka, often through networks of traditional builders and artisans, and prioritize rescuing them from demolition. The salvaging process involves carefully disassembling the homes, labeling each joint and frame member, and transporting them to a warehouse for cleaning, inspection, and repair. Components like ceramic roof tiles, tatami mats, doors, and shoji screens are also salvaged whenever possible. The timber frames are then reassembled to ensure structural integrity, documented, and finally disassembled again for shipping, often to other countries. One notable project involved the reconstruction of a kominka in northeastern Oregon. Eric Carlson, a long-time admirer of Japanese architecture, initiated this endeavor after observing discarded materials from old houses in Japan. Collaborating with Kunito Niwa and members of Toda Komuten, he helped establish the Kominka Collective to export these frames to North America. The first frame was used to build a 600-sq.-ft. structure on Carlson's property. Inspired by this, neighbors Bill Oliver and Kiyomi Koike commissioned the Collective to build a tea and guesthouse, expanding their initial request for a small studio. The project involved a hybrid design, blending traditional Japanese elements with modern building practices to meet local codes. The reconstruction process in Oregon combined salvaged sills, floor joists, and exposed timber roof framing with modern materials and Western building assemblies. New foundations were laid, and the salvaged 6x8 cypress beams were installed using traditional timber-frame joinery. The space between exterior posts was infilled with 2x6 walls, and mortise-and-tenon joints were secured with hidden structural lag bolts for code compliance. The reclaimed kominka roof framing, with its complex arrangement of crossbeams and natural shapes, was left exposed to the interior, providing an aesthetic connection to the home’s heritage. An over-roof with 2x12 rafters and R-40 fiberglass insulation was added to enhance comfort and energy efficiency. Lightweight enameled steel panels were used for the roofing, mimicking traditional Japanese tiles without adding excessive weight, and Japanese cypress was utilized for exterior wood details due to its weather resistance. The exterior walls featured a plaster finish achieved by applying a limestone-based stucco over tile backer panels, as traditional Japanese plaster was difficult to source. Decorative frame-and-panel details made of enameled steel were also incorporated at the lower portion of the exterior walls. The project, which took nearly a year, including delays from weather and the global pandemic, allowed for careful design decisions. The owners expressed that the completed Zen House Kominka offers a unique blend of vibrancy and serenity, transcending cultural boundaries. This initiative not only preserves traditional building arts but also offers an appreciation for kominka and the ancient Japanese timber-framing tradition, known for its flexible joinery and resilience against earthquakes, exemplified by structures like the Horyu-ji Temple, one of the oldest wooden-framed buildings in the world. #KominkaCollective #JapaneseArchitecture #TimberFrame #HistoricPreservation #SustainableBuilding #CulturalHeritage #HomeDesign #TraditionalCraftsmanship #OregonConstruction

Local architectural practice Slow has completed the Yamaguchicho House in Nagoya, Japan, a family home characterized by its raw exterior of blackened wood and corten steel, topped with an overhanging pitched roof. Situated on a slightly elevated corner plot surrounded by roads, the design prioritizes privacy, featuring an almost windowless exterior. Natural light is introduced through strategically placed skylights, contributing to the interior's 'healing' and sanctuary-like ambiance. The entrance to the single-story residence is framed by a corten steel box, accessible via a sloping garden that wraps around the building. The interior layout is centered on a combined living, dining, and kitchen area, which subtly steps up to two bedrooms located in the western, slightly elevated section of the home. A central bathroom, enclosed by exposed concrete walls, effectively divides these primary living and sleeping zones. These concrete walls also serve as a backdrop for the kitchen counters, seamlessly integrating the functional spaces. Michitaro Kondo, founder of Slow, explained that the design incorporates a concrete box within a wooden box, divided into three layers—gathering, plumbing, and private space—with ceilings and glass connecting these areas. This arrangement fosters a sense of familial presence throughout the residence, allowing occupants to remain aware of each other's activities. Illumination further extends from a skylit entrance area through an elevated storage unit crafted from black wood, which also demarcates the living space. A large horizontal window in the southern end of the living area offers views of the road, while a row of small trees in the garden provides both shade and privacy. Above the exposed wooden roof, a compact mezzanine area is accessible via a slender black steel ladder in the living space, offering additional utility or a secluded retreat. The bathroom features a shower and bath positioned beside a large window, overlooking a small courtyard enclosed by a section of charred cedar cladding. The interior material palette is intentionally minimal, with white walls providing a stark contrast to the exposed wood of the ceiling and the concrete elements of the bathroom. Kondo noted that the choice of baked cedar and steel for the exterior was aimed at creating a structure that, while simple and 'hut-like' in appearance, presented an unprecedented architectural style within the local area. This approach emphasizes a unique aesthetic without being overtly flamboyant. The project aligns with other contemporary Japanese homes that embrace a minimalist design, such as the conversion of a century-old home in Shimane into a guesthouse by Studio AMB and a Tokyo residence designed as a singular large room by IGArchitects. #JapaneseArchitecture #CharredWood #CortenSteel #NagoyaHouse #MinimalistDesign #Skylights #ResidentialArchitecture #PrivacyFocusedDesign

Shou sugi ban, known as yakisugi in Japan, is an ancient Japanese technique originating in the 18th century, primarily used to protect rural homes and warehouses from fire. This method involves charring wood, which paradoxically makes it fire-resistant. Traditionally, the technique used Cryptomeria japonica, also known as Japanese cedar, though Western applications now utilize other wood types. The process includes charring, cooling, cleaning, and finishing the wood with natural oil, offering a chemical-free preservation method. This technique is currently experiencing a modern resurgence in the West due to its aesthetic appeal, durability, and eco-friendly properties. The article showcases eight different modern homes and structures that have incorporated shou sugi ban into their design.
