Obi: the sash, its construction and the finished knot
帯
An obi is a long textile sash worn around the waist with Japanese dress. Its effect depends on the sash’s width and construction, the way it is shaped into a knot, and any supporting accessories. Fukuro-obi names a kind of sash; otaiko names a way of arranging it.

Sash types, knot forms and accessories describe different things.
Other ties used in dressing also help secure a kimono.
Wide and narrow forms serve different uses rather than one simple hierarchy.

Wrapping length and working ends
Once the sash is wrapped around the waist, its ends contribute to the knot; Japanese dressing terminology distinguishes their roles as te and tare. A sash laid flat reveals length and folded areas that a photograph of the finished back arrangement can conceal.

Different ways of constructing a wide sash
Maru-obi fold a broad patterned textile so that both faces can carry decoration. Fukuro-obi commonly combine a patterned face with a plain backing. A Nagoya-obi usually has its waist section already folded to half width, while the part forming the otaiko remains wider. Construction changes material use and handling.

Narrow and soft forms
Hanhaba-obi are narrower sashes used with lighter dress such as yukata. Kaku-obi have a firmer form and are a familiar choice in men’s dress. Heko-obi use softer fabric that produces a less rigid knot. Clothing, occasion and the wearer shape the selection.

Knot forms and supporting accessories
Otaiko forms a folded, box-like loop at the back with a short tail below. Bunko has wing-like folds spreading to either side. An obi pillow supports the arrangement; obiage covers the pillow, obijime holds the knot against loosening, and an obi board smooths the front. The accessories used depend on the arrangement.

A more visible sash, then changing uses
The kosode made the sash more prominent
Kazuko Aoki’s study connects the sash’s development with the kosode becoming outer dress in the Muromachi period. Narrower forms continued through Momoyama and early Edo before increasing width and decoration. The Kyoto kimono-industry foundation also describes kabuki’s influence on wider sashes, back arrangements and patterns.

A familiar story connects otaiko with Kameido Bridge in 1817. Aoki’s study compares earlier images and texts with later terminology and identifies precedents. The form and its name developed over time, rather than being fully explained by that single story.

The print is an earlier visual witness for comparison with the modern rear view above; it does not establish an identical tying method.
Modern construction addressed material and handling
Taishō-period changes involving fukuro-obi and Nagoya-obi addressed fabric use, weight and ease of dressing. A pre-folded waist section reduced the need to fold that length while putting it on. Accessories helped create familiar modern shapes, while several sash types continued in use.

The school dates the development to around 1915 and commercialization under the Nagoya name to 1924. The illustrated object and photograph are individually undated.
The Showa Memorial Museum describes postwar shortages followed by urban women’s increasing adoption of functional Western-style clothing, with a shift in relative use around 1955 in cities. Mito City Museum traces kimono’s changing emphasis from everyday wear towards festive occasions such as Shichigosan and coming-of-age celebrations. Obi use changed with these contexts without everyday wearing disappearing entirely.
