Shiozawa tsumugi

Shiozawa Tsumugi belongs to the Shiozawa textile area of Minamiuonuma City in Niigata Prefecture. It is a silk kasuri weave used mainly for kimono cloth; within the wider Shiozawa weaving context, it is discussed alongside Hon-Shiozawa, while its own surface comes from hand-spun mawata silk and fine kasuri patterning. Its 1975 designation as a national traditional craft is best read as background that clarifies place, material, and technique boundaries after the fabric itself has been understood through yarn and loom work.

The weaving background of Shiozawa is often traced through Echigo Jofu: hemp cloth woven in the region in the Nara period is preserved at the Shosoin in Nara. Shiozawa Tsumugi is described as a silk textile made by applying techniques from that hemp weaving tradition; one account says it began in the Edo period, while the Shiozawa Tsumugi Memorial Museum places the creation of mawata-yarn Shiozawa Tsumugi in the Meiwa years of the Edo period. Here, tradition means a specific technical passage in Shiozawa, from hemp cloth to silk cloth, and from fiber handling to dyed yarn and woven pattern.

For Shiozawa Tsumugi, the warp uses raw silk or tama yarn, and the weft uses hand-spun mawata silk. The mawata yarn is drawn out by hand while the silk floss is opened with the fingers; the pressure and movement of that drawing decide the fineness of the thread. Once placed into the weft, this yarn gives the cloth a soft, lightly full touch, and the difference between warp and weft materials helps explain the textile’s distinctive feel.

Shiozawa Tsumugi is woven after the yarn has been dyed, so the pattern must be planned before the loom begins. The work starts with a design on graph paper, where the positions of kasuri and the lengths of yarn are set; a kasuri ruler is then made from that design. Threads are marked with ink along the ruler, tied by hand at the marked points, or rubbed with dye using a bamboo spatula; board clamping is another listed method for dyeing kasuri yarns. These actions break the future motif into marks on individual threads before the pattern is reassembled in woven cloth.

Dyed ground yarns and kasuri yarns are prepared as wound bundles and set on the takahata loom before weaving can begin. A standard Shiozawa Tsumugi setup uses about 1,260 warp threads, and the weft is beaten in with a hand-thrown shuttle. The maker sends the shuttle across and aligns each kasuri thread with the motif; the calm surface of the finished cloth depends on yarn length, ink marks, warp order, and repeated shuttle movement working together.

Shiozawa Tsumugi is often described through cross kasuri, tortoise-shell kasuri, and mosquito kasuri. The cross and tortoise-shell names point to small geometric forms, while mosquito kasuri refers to especially fine kasuri marks. These patterns are not applied after weaving; they appear when threads dyed by tying, dye rubbing, or board clamping meet in plain weave. The quiet refinement associated with Shiozawa weaving comes from these small changes of yarn color and the careful alignment on the loom.

Near JR Shiozawa Station, the Shiozawa Tsumugi Memorial Museum gathers displays of Shiozawa weaving and its techniques in one place. Its second floor shows the steps by which textiles are made, and visitors can encounter loom-weaving practice there. For understanding Shiozawa Tsumugi, the setting places mawata yarn, kasuri preparation, the takahata loom, and patterned cloth back beside the streets of Shiozawa in Minamiuonuma, instead of leaving the textile as a name alone.
