MEET THE TAKUMIS: REFLECTIONS OF LUXURY

  • The all-new Lexus ls is a story of craftsmanship. the story of kiriko glass, fitted to the interior doors in selected grades is a notable example – collaborative craftsmanship resulting in a unique and beautiful ornamentation.

    In early 2014, Lexus and Asahi Glass Company (AGC) together began to explore how to use glass in vehicle interiors to express Lexus’ distinctly progressive perspective on luxury. Eventually this led to the Kiriko glass concept for the all-new Lexus LS flagship.

    Kiriko, a unique Japanese tradition of hand-cutting delicate patterns into glass, produces stunning reflections of light, depending on the angle of both the light and the viewer’s gaze. Examples can be appreciated in vases, sake glasses and traditional glass ornaments.

    An industry giant, AGC’s wide range of glass products include smartphone screens and television panels, as well as automobile windscreens and windows. Despite their decades-long expertise, Kiriko would require a completely new glass-molding process. It was, recalled AGC’s Hideki Ishioka, “Completely outside our traditional scope”. It also required an artisan to design and craft an exquisite, elegant Kiriko glass prototype.

  Toshiyasu Nakamura - Takumi craftsman

    AGC turned to Kiriko glass Takumi craftsman, Toshiyasu Nakamura, a native of Toyama City, home to the well-known Glass Art Museum, a showcase of glass artisanship. Nakamura was tasked with re-creating Kiriko’s reflective effect in glass panels.

    These ornamental panels, to be fitted to the LS door interior, provided a unique challenge for Nakamura. Unlike the reflection in a Kiriko sake glass, prominent when held and moved around in one’s hand, a door panel is relatively fixed and a standard Kiriko glass cutting pattern might not draw out the desired characteristic.

    Running his finger along the lines of a cut-glass model, Nakamura described his thoughtful solution, “Cutting at altering angles through the hand-drawn lines on the glass results in a ‘twist’, allowing more light to reflect at different angles along those lines,” he said, resulting in a distinctive and startling effect. He also hopes LS passengers will be able to enjoy these reflections at all times, with night driving yielding further reflections.

    Nakamura’s meticulous methodology allows for this delicate and exacting design process – draw, cut and polish – to be accompanied by several rounds of quality inspections, necessitating only a single, final review on completion.

  • From this point, it’s another eighteen months before the final Kiriko glass panels are ready to be fitted to the LS, and this journey is a story in itself. Multiple panel reproductions – exact facsimiles of Nakamura’s craft – were a singular challenge, while an automobile’s rugged environment requires a durability far beyond that of regular Kiriko pieces. For this venture to be a success required AGC to invent a whole new eight-stage process, carried out in eight different locations across Japan.

    To state that AGC built a new mold to duplicate Nakamura’s design would be an understatement. His ‘twist’ lead to the incorporation of a never-before-implemented 3D digital scan when designing the mold, faithfully rendering the glass panel’s unusual dimensions and accurately reproducing its unique expression. “That’s something we never did before,” explains Ishioka, “That area was a real challenge for us.”

    Partner vendors were carefully vetted to complete the remaining stages – finishing, polishing and strengthening. The latter achieved with both a film-dipping process and rear-mounted metal plating, providing the Kiriko piece a sturdiness that belies its delicate appearance. Their attitude and energy to exceed expectation impressed Ishioka, “Our partners go beyond simply completing their task. They also infuse their work with passion and emotion,” he said, in keeping with the spirit present throughout the LS’s production journey.

    Due to the Kiriko panel’s unique, irregular shape, even transporting batches between vendors required an all-new logistical approach from AGC, with customized packaging materials, and innovative delivery processes ensuring quality throughout the panels’ journey.

    Quality control is taken seriously by a company used to delivering products of exacting standards to the bio-tech, electronics and optics industries but even this existing process was insufficient. Above and beyond an already rigorous quality inspection, in another first, AGC must ensure the final output matches Nakamura’s prototype not only in accuracy and polish – but also in beauty.

  • It is difficult to fully comprehend the beauty of Kiriko glass without seeing it in person. To follow the cut glass lines with one’s own eyes, and marvel at the light subtly glistening in different directions as your viewing angle adjusts.

    This finished ornamentation represents both Nakamura and Ishioka’s shared vision of Japanese beauty and luxury. Nakamura reflects, “To me, Japanese beauty represents a subtlety and depth that reveals detail and craft the more one observes. As reflected in the Kiriko glass, looking at it from different angles yields different aesthetics, yet it conveys an overall sense of harmony and connectedness.”

    This might also describe the union of Nakamura’s Takumi craftsmanship, and Ishioka’s passionate willingness to push the boundaries of industrial technology. Nakamura concluding, “The partnership of traditional hand-made artistry and leading-edge industrial processes is – in itself – a form of craftsmanship.”
