The back strap loom, called zhi-bata, izari-bata, or koshi-bata in Japanese, has been decreasing in numbers recently. However, a few weavers of Yuki-tsumugi still use this type of loom. Various types of back strap looms, in which weavers control the tension of the warp with their lower back, exist in the Pacific Rim. In the past, a frame was built for the primitive back strap loom to improve its ease of use and the quality of the textiles, and it is referred to as kidai-tsuki-koshi-bata or tenbin-koshi-bata. This type of loom is found in Japan, Korea, and China.
Recently, dozens of back strap looms faced the danger of being scrapped in Aomori. We hope to preserve these valuable resources for modern times and their way of life, and have therefore decided to hold a back strap loom workshop.

The difference between the floor loom and the back strap loom

There are key differences between the floor loom and the back strap loom.
With a floor loom, the warp is kept at a consistent tension between the front beam and the rear beam, but the weft can tend to wave.
On the other hand, with a back strap loom, the warp between the weaver's lower back and the rear beam changes tension as the weaver moves their lower back forward and backward, causing the warp to tend to wave.
This requires skill to create a beautiful selvage.
We look forward to receiving your registration!
