Tochigi Prefecture: Japan’s Silk Road

  • SPOT
  • As you head to Tochigi Prefecture, just north of Tokyo, the high-rises gradually disappear and space opens up to make room for farm fields and rushing rivers. Mountains ring the horizon, snow-capped in winter and lush with verdant greenery in summer. Here, where the Kinu River cuts a wide swath, more than a thousand years ago, silkworms arrived from China and farmers planted mulberry trees to feed them. The river’s history of flooding left behind a rich topsoil ideal for growing everything — including an economy based on silk production.

    Crafting a Brand


    “Our ancestors used the damaged cocoons to make work clothes,” says Kazuhiko Soutome, the director of the Tochigi Prefectural Industrial Technology Center. “If there were any holes in the cocoons, they could not be used to make the regular silk threads. This is how yuki tsumugi (a hand-woven silk) began.”

    Today, yuki tsumugi is inscribed on UNESCO’s Representative List of the Intangible Cultural Heritage of Humanity.

    “It was very popular. One kimono from the region cost two horses during the Edo period,” said Takeji Okuzawa, of the Tsumugi Fabric Museum and the fourth generation to run his family’s silk wholesale business. Rumored to be strong enough to protect its wearer from a sword attack, yuki tsumugi was mostly worn by men. “During the Meiji period, though,” Okuzawa explained, “the Japanese government encouraged men to wear Western suits so manufacturers began making colors and patterns for women.”


    Unlike regular silk thread, which consists of five single strands, yuki tsumugi is a single, untwisted thread. The act of spinning the fibre alone — drawing a strand of silk from the flossy silk firmly but gently, wetting it with a bit of saliva and letting the end fall into a wooden bucket in front of the weaver before drawing again — requires three years of study. It is just the first of 47 steps required to make a bolt of cloth.

    Color of Silk


    Patterns are added using different methods — either before or after dyeing — depending on the color. If the base hue is dark, then tiny knots are tied with cotton string along the full length of the warp and weft. The warp is the tightly stretched lengthwise core of a fabric, while the weft is woven between the warp threads to create various patterns. “One length can have 3 million knots,” said Naoyuki Akaishi, the staff of Omoigawa, one of the weaving houses in Tochigi. “The cotton shrinks during the dyeing process, so the color can’t penetrate.”

    If the base color is light, then a design is painstakingly stenciled onto the threads. “They apply each color individually,” said Nobuko Suto, owner of weaving house. “Only one person does the warp and weft to reduce errors.” A complicated design can take more than three months to complete before weaving even begins. A whole kimono, from start to finish, can take more than a year and cost up to ¥4,000,000 (approximately US$35,400).

    Tying it all Together


    No kimono is complete without the obijime, the decorative woven silk strap that wraps around the obi. Mamada Himo, a shop started 95 years ago, is one of the few places still making them by hand. “It is, literally, what holds everything together,” said Yasuhisa Watanabe, the fourth generation of his family to run the shop. While he and his cousin, Kumiko Ishida, fill orders from around the country, they also make modern accessories such as necklaces, earrings and bracelets.
