While tatami mats have always been a vital part of the Japanese lifestyle, tatamiberi, or the border hem that protects the corners of tatami and also fills the space when laying the mats side by side, gets little attention. However, a manufacturer offers this tatamiberi, which has been made in a wide variety of patterns since ancient times, which can serve a variety of different uses in the present day. Matsui Orimono is located in Okayama Prefecture, one of the two major domestic production areas of tatamiberi. Nowadays, tatamiberi is often woven with the same Jacquard loom as neckties and are offered in diverse patterns. The use of synthetic fibers also makes it resistant to dirt and stains. Taking advantage of these characteristics, it can be used for various items such as device cases, denim pants and guitar straps. The company will continue to provide new life to tatamiberi from fresh perspectives.
