At the center, the threads gradually interlace into a perfectly uniform round cord that rises steadily from the top of the mechanism. The naikidai uses wooden gears to coordinate the movement of weighted bobbins, known as tamas, which keep constant tension on every strand. At the Nakamura Sho Workshop, the threads cross in a precise sequence, interlocking at the center to form an intricate Edo Kumihimo braid with remarkable consistency. The Nakamura Sho Workshop continues a tradition dating back to Japan's late Edo period, preserving one of the rarest methods of producing Edo Kumihimo. These braided cords were historically used for samurai armor, kimono accessories, and ceremonial garments, and remain highly valued examples of traditional Japanese craftsmanship today.
