Seiga [清雅] The Architecture of Refinement

Presented by: Michael Raba for AS 390

Heritage: A Ningen Kokuho (Living National Treasure) representing the third generation of the Suda woodworking lineage.
The Seiga [清雅] Spirit: His work is defined by "Refined Purity," evolving 2,000 years of Monozukuri history into modern wood art.
Shift in Role: His career tracks the transition from the Sashimono-shi (technical joiner) to the Mokko-geika (woodworking artist).

The Power of Mulberry [桑]: Suda utilizes Mikura Island Mulberry—the legendary material of Edo Sashimono, often combining it with Sycamore to bridge ancestral techniques with modern aesthetics.
A 2,000-Year Timeline: Suda views joinery as a “complete” technology since the 1st century; he works to keep this ancient lineage breathing in the present day.
Ebijo [蝦錠]: A rare artist-blacksmith, Suda hand-forges his own “shrimp-shaped” locks based on 6th-century Asuka Period designs to give his wood “historical gravity.”

Beyond Work: For Suda, being in the workshop is not "labor" but simply living. The act of creation is inseparable from existence.
Mederu [愛でる]: The philosophy of "loving and cherishing" ordinary objects. He believes beauty must be rooted in the home and daily use, not just the gallery.
Nature’s Revelation: As seen in his Suiko and Tsukuhae boxes, he planed a blackened, discarded log to reveal grain patterns like "moonlight on dark water."

Concept: Organizing rectilinear planes with a “Seiga” (refined purity) motif. The formal elements emphasize horizontal massing, where the “S-curve” of the leg-to-apron transition creates a fluid line from the ground to the surface.
Structure: A codependent structural system. The table utilizes traditional Sashimono (blind joinery) to handle the tension of the cantilevered top. The relationship between the low height (32cm) and the wide span (114cm) requires high-precision compression joints to prevent racking without metal hardware.
Materials: Deploys Kenponashi (Japanese Raisin Tree/Pear) for its refined grain and Enju (Japanese Pagoda/Locust) for structural density. These choices balance the aesthetic need for “shimmer” with the functional requirement of a load-bearing surface.

Process: Fabricated using 2,000-year-old assembly methods, planed by hand to achieve a "wiped" finish that highlights the grain. The process itself is the aesthetic; every joint interface is a visible testament to mastery.
Context: Designed for high-end residential or traditional Washitsu (Japanese room) environments. Targets elite collectors/museums, justified by Suda's status and the "complete" technical mastery required for glue-less joinery.

Concept: Formal organization of rectilinear planes and rhythmic repetition; grain “chatoyancy” contrasts with dark vertical massing.
Structure: Codependent Sashimono (blind joinery) system; relies on precision-fit compression and mechanical locking without fasteners.
Materials: Curly Maple selected for aesthetic shimmer and high structural density; technology of the hand expressed through grain-matching.

Process: Sequential interlocking of tsugite joints; fabrication is elevated to an aesthetic by exposing joinery as a serrated decorative element.
Details: Large maple chassis; Medium rhythmic joinery “teeth”; Small metal pins and circular surface inlays.
Context: Functional sculpture for institutional/collector environments; labor-intensive fabrication justifies high-end retail price point.

Process: Fabricated using high-precision Sashimono (wood joinery) and finished in wiped lacquer (urushi) to accentuate the grain without masking the tactile surface.
Details: Large interlocking walnut planks; Medium cherry structural beams; Small precisely carved joint interfaces where the “planks” meet the frame.
Context: A monumental functional sculpture intended for institutional or high-end residential interiors; its status as a work by a Living National Treasure places it in a high-luxury price bracket for serious collectors.
