Fukuro obi: construction before the knot

Hon-fukuro construction weaves the two faces together as a tubular textile. A sewn fukuro obi joins separate front and back fabrics. A maru obi instead begins with a wider patterned cloth folded lengthways. The finished front of a knot hides these differences, which become clearer when the sash is laid out and its edges inspected.

A zentsū pattern runs along the full length. Rokutsū arrangements reserve decoration for much of the sash while leaving areas concealed during wear relatively plain. Wrapping and arranging the fabric places the decorated sections at the front and back.

The sash and the knot

The Nishijin Textile Industrial Association includes fukuro obi suitable for formal, semi-formal and some less formal kimono. Weave, design and materials affect how an individual sash is worn. It can be arranged as a nijūdaiko, a double-layered taiko form, or in decorative knots with a furisode, a kimono with long hanging sleeves. The sash and the arrangement made with it have different names.

Two layers in nijūdaiko

Kawashima Selkon’s comparison locates the “double” in the taiko portion at the back: two layers of folded sash overlap there, rather than the single layer in a single taiko. This describes the finished arrangement, distinct from the face and backing that make the sash itself tubular.

Changes in modern dress

The National Museum of Ethnology’s dress-history notes describe fukuro obi gaining popularity in the early 1900s, following some earlier use. New constructions, including Nagoya obi from the 1920s, changed the position of the heavier maru obi. Several types coexisted, while maru obi continued in bridal and other specialised dress.

Equipment and product changes

Production changed too. Jacquard equipment introduced to Nishijin in 1873 read punched-card instructions to control warp threads, providing a new way to weave complex patterns. This was a regional technical change, not a single invention date for fukuro obi. Kurata Shōten, founded in 1939 and later named Miyako, initially produced both Nagoya and fukuro obi. It developed different sash lines after the war and later gave greater weight to brocaded fukuro obi. Continuity involved changes in equipment, product mix and the demands of dress.

An obi makura helps give a taiko arrangement its volume; obiage fabric covers and tidies the support, and an obijime cord helps hold the arrangement. The rectangular shape seen at the back is produced by fabric and supporting accessories working together. It is not simply one unsupported knot in a broad sash.
