Why we chose them
Takiron Rowland’s importance greatly outweighs its renown. It doesn’t make the finished designer sunglasses you see in luxury boutiques, nor is its name printed on the temple or found anywhere identifiable. Its mark is invisible, but it shows up in the bones of any eyewear piece made using its Japanese acetate.
It’s part of a much older, richer Japanese history of working with plastics. The Takiron business traces its origins to 1919, when Sataro Takigawa established Takigawa Celluloid Works in Osaka to manufacture regenerated celluloid sheet. By the 1920s, it was producing decorative pearl-effect celluloid and, in 1935, established the Aboshi factory in Hyogo Prefecture. As materials evolved after the war, so did the company; Takiron moved from celluloid into newer synthetic materials and developed considerable expertise in sheet extrusion, forming, and plastics engineering. Takiron Rowland was established in 1969 as an affiliate of C.I. TAKIRON, positioning itself globally as the only Japanese specialist manufacturer of eyewear plastics. Now, it remains the only Japanese acetate manufacturer and is integral to the country’s celebrated Made-in-Japan eyewear industry.
Japan’s reputation for acetate eyewear is rooted in Sabae, where specialist workshops cut, shape, tumble, polish, and assemble these famous frames. To maintain the extraordinary frame-making culture and community, the craftsmen have established a well-oiled supply chain for raw materials. Takiron Rowland is at its foundation, supplying the acetate and cellulose sheets from which the frames are carved.
Its acetate begins with cellulose-derived materials, including cotton linters and pulp, which are transformed into a transparent resin that is receptive to colouration, able to take on vivid hues and patterns. Takiron applies extrusion and press manufacturing to work the material. Extrusion introduces different colour resins in a delicate way, creating patterns before the sheet is rolled to the correct dimensions and begins the cooling process. Pressing allows separate materials to be arranged, heated, and compressed together before they are slowly cooled, sliced to thickness, and surfaced. Finished sheets are inspected for dimensions, colour, pattern, surface condition, and contamination before they are released.
There’s an important, less visible technical distinction behind the sheets. Takiron uses a dry manufacturing process that doesn’t involve adhesives or solvents, and limits the quantity of plasticiser used in its sheets. The result is higher gloss and minimised deformation caused by ageing. It’s a good example of how Takiron stands apart: the acetate produced is beautiful, and retains that beauty long after it’s made into a frame.
Colour, specifically, is at the forefront of Takiron’s process and anything but an afterthought. Its library includes an extensive vocabulary of solid, transparent, layered, and patterned acetate, both old and new, as Takiron continues to develop designs for eyewear manufacturers. Its ability to work in small production lots is crucial for smaller labels and independent brands, allowing more specialised colours and designs to be developed without the quantities associated with industrial mass production. Takiron’s role goes beyond that of a mere supplier: its technicians work alongside designers to translate ideas into original materials and patterns. It doesn’t function simply as a catalogue supplier or stock colour warehouse.
That combination puts Takiron Rowland in an unusual position within global eyewear. Italy has Mazzucchelli 1849, the historic giant renowned for Italian acetate, famous for having an extraordinary archive of colours and patterns. And Japan has Takiron Rowland. The comparison should not be reduced to comparing decorative versus technical capabilities: both are sophisticated, elegant material manufacturers. But Takiron is inseparable from Japanese eyewear culture. Specialisation, precision, controlled production, and an extraordinary amount of attention are paid to perfecting plastics the brand or designer may never see. Decisions about these key attributes must happen on the frontline, where the plastics are made.
Its importance is no longer confined to Japan. Takiron Rowland acetate has been increasingly adopted by eyewear brands overseas, and its parent group has invested in expanding acetate production capacity. And yet, Takiron’s name remains relatively unknown, a remarkably quiet company considering how much influence its product has.
Japanese eyewear is rightly celebrated and growing with global acclaim, anchored by a strong reputation for quality. That reputation hinges on Japanese craftsmanship, but also on the Japanese materials behind it, and the two are increasingly diverging as European and global brands import Japanese materials to use as parts. But a designer can only reveal what is already built into its materials. Before Sabae can do what it does so well — cutting, bevelling, polishing, and assembling a finished designer eyewear piece — someone has to make an acetate sheet stunning and noteworthy enough to work with.
Takiron Rowland has been doing exactly that for over 50 years.
