Kogin
Kogin, or kogin-zashi, is a kind of sashiko, Japanese reinforcing stitching, from the Tsugaru region of present-day Aomori prefecture in the far north of Honshu. It is generally white cotton thread stitched in diamond patterns on indigo-dyed linen. The name comes from kogin, the local word for a work garment.
Definition
What sets kogin apart from other sashiko is counting: each stitch passes over an odd number of threads of the warp. Stitched over even counts, the same idea becomes hishizashi, the diamond stitching of southern Aomori. The repeated small motifs join into larger diamond patterns.
Origin
Cotton could not be grown in cold Tsugaru and was expensive to bring in. In 1724 a sumptuary order for farmers forbade them to wear cotton for work or everyday clothes, and they wore indigo linen, which kept out little of the winter cold. When cotton thread became available in the Meiwa era, 1764 to 1772, farm women stitched it into the linen, filling the weave so that the cloth held warm air; the dense stitching also protected the shoulders from wear by carrying straps. After the Meiji period abolished the old class rules, cotton cloth came into general use. Kogin garments were re-evaluated in the early Shōwa period by Yanagi Sōetsu and the mingei folk-craft movement.
Three styles
- West kogin. From west of Hirosaki castle: fine cloth, horizontal stripes at the shoulders and a protective motif on the back.
- East kogin. From east of the castle: thicker cloth, large all-over patterns and no stripes.
- Three-stripe kogin. From the Kizukuri and Kanagi area: three broad stripes from the shoulders down, reinforcing where loads were carried.
Named motifs include the butterfly, the flower, the bean, scales, cat's eye, rice-field paths, horse's bit and cow; some 300 are recorded.
Key facts
| Region | Tsugaru, Aomori prefecture |
|---|---|
| Materials | White cotton thread on indigo linen |
| Rule | Odd counts over the warp |
| Sumptuary order | 1724 |
| Cotton thread | From the Meiwa era, 1764 to 1772 |
How to identify it
- Counted diamonds. Regular geometric patterns built from short horizontal stitches.
- Ground and thread. Indigo linen or hemp in old pieces; cotton in later and modern work.
- Old or new. In our handling, old kogin has softened, faded indigo and worn stitching at the shoulders; modern kogin-style clothing is made in the same manner, and we describe it as such.
Where it appears in the collection
Modern kogin appears in Porter Classic clothing, such as a kogin no-collar jacket in blue cotton; our guide to Porter and Porter Classic explains the maker. Old Japanese textiles sit on the kimono and textile archive.
