Urashima 裏縞 - うらしま Folding Umbrella 60cm 10 bones

The fabric used is "Koshu-ori," which is intricately woven in Yamanashi Prefecture, a famous textile production region with a history of over 400 years.
Koshu-ori is a "pre-dyed" fabric made by weaving extremely fine yarns that have been dyed beforehand into a high density, uniform weave.

This has resulted in a glossy, deep color and an elegant, heavy texture, and the product still boasts high quality today.
The weaving technique that uses double yarn (twisted yarn) for the warp and single yarn (one thread) for the weft is characteristic of Yamanashi textiles, resulting in a fabric that combines luxury and durability.

The production of Koshu-ori fabric begins at a dyer's shop, where the threads are dyed, then goes through a warper, where the threads are arranged into warp threads, before being sewn into fabric at a weaver's shop.
The fabric is carefully woven over a long period of time, and is then treated to be water-repellent, water-resistant, and UV-resistant, before it can finally be used as an umbrella.
In this way, the fabric that has been made by many people is then cut and sewn by craftsmen to make into umbrellas.
