Murayama Oshima tsumugi

The first anchor for Murayama Oshima Tsumugi is the land itself. The Murayama area lies on the southern foot of the Sayama Hills, while today’s main manufacturing places are Musashimurayama, Mizuho, and Akishima; those names keep the textile within a specific part of western Tokyo.

A second anchor stands in Musashimurayama’s Honcho district. The Murayama Textile Cooperative office at Honcho 2-2-1, a wooden building from 1928, now holds displays of tools, process stages, cloth bolts, and local textile chronology. The building connects the cloth to loom houses, kasuri-board makers, and a producer community that worked around the same area.

Before silk tsumugi became the focus, the Murayama area was known from the Edo period for cotton indigo kasuri. Another layer of the area’s textile past reaches to Genroku-era striped cotton and late-Edo Murayama kasuri, giving the later silk cloth a local background in cotton weaving and patterned yarn.

From the Meiji period into the Taisho period, cotton kasuri was developed and production increased. Around 1919, board-clamp dyeing came from Isesaki in Gunma, and silk textiles became more common in the area; Murayama Oshima Tsumugi grew from that shift toward raw silk, pre-dyeing, and plain weave.

In Murayama Oshima Tsumugi, the pattern starts before the loom. Board-clamp dyeing uses patterned boards to dye kasuri yarn, so the yarn already carries positions for the design before weaving begins; its introduction from Isesaki around 1919 gave the area a practical way to make silk kasuri.

That dyed yarn is used in both warp and weft. Board-clamp dyeing therefore has to meet the later work of plain weaving and hand alignment: when the prepared raw-silk yarns cross on the loom, the pattern appears in the cloth rather than being added on top of it.

The thread structure is precise. The cloth has warp yarns running lengthwise and weft yarns passing across the width; each direction is divided again into plain ground yarn and board-clamp-dyed kasuri yarn. Even before weaving, four thread roles have to be prepared.

The work is described as handwork throughout, with the workflow often subdivided into about forty processes. Raw silk, ground yarn, kasuri yarn, dyeing boards, and loom preparation all sit in sequence before a bolt of plain-woven tsumugi can take shape.

At the loom, the maker aligns warp kasuri and weft kasuri by hand. The pattern depends on that meeting point: two dyed directions cross in plain weave, and the cloth surface gains its fine kasuri design through small adjustments in the yarns.

The finished cloth is known for a smooth touch that still lets the fiber be felt, and for a lightness that makes long wear less tiring. Men’s cloth often uses very fine kasuri that looks intricate up close and nearly plain from a distance, while women’s cloth emphasizes subdued patterns and colors suited to a range of ages.

The Murayama Textile Cooperative office in Honcho was built in 1928, when textile businesses in the area organized around their shared work. The Musashimurayama area and nearby districts had many loom houses and kasuri-board makers from the Taisho period, and that local network is still legible in the building.

Inside, visitors encounter tools, production stages, board-clamp injection dyeing, historical cloth bolts, chronology panels, and video material on the making process. These objects keep the craft at hand-sized scale: boards, yarn, loom, cloth, and moving images show how Murayama Oshima Tsumugi travels from thread to textile.

Murayama Oshima Tsumugi has long been connected with kimono, helped by its fine kasuri surface, smooth touch, and light feel during wear. Whether used in men’s fine-patterned cloth or women’s subdued designs, the cloth keeps the hand-matched warp and weft visible in small details.

The same textile is now also made into ties, pen cases, drawstring bags, and coin purses. In these smaller objects, the board-clamp-dyed yarn and warp-and-weft alignment remain visible on a reduced surface, bringing the Musashimurayama-area silk kasuri into daily use beyond a full kimono bolt.
