Along with Gobelins in France and Persian carpets in Iran, it is one of the world's three major textiles, and has a long history of about 1,300 years and is considered the queen of kimonos.
When the Ministry of International Trade and Industry (MITI) designated Oshima silk as a traditional craft in 1975, it clearly defined the requirements for Oshima silk, such as being made of 100% silk and hand-woven with yarn-dyed threads.
In addition to being supple, lightweight, and wrinkle-resistant, Oshima tsumugi can be used long into one's grandchildren's generation because the dyeing process, described below, soaks the threads with iron and prevents them from falling apart or being eaten by insects.
The beauty of the delicate folded patterns based on the unique blackish-brown color is also highly valued, and it is known as one of the most luxurious silk fabrics among Japanese silk fabrics. The cheapest piece costs about 300,000 yen (2,350 dollars) per roll, while the most expensive costs several million yen(Tens of thousands of dollars).Wikipedia
