Shichitoui is a member of the Cyperaceae family, now cultivated only in Oita Prefecture. Shichitoi is used as a material for making Ryukyu tatami mats and has been a part of Japanese life for over 350 years. As it is more durable than tatami made of rushes, it was used in the 1964 Tokyo Olympics for judo competitions at the Nippon Budokan. A checkerboard pattern appears due to the reflection of light by alternating the grain of the tatami when placing them. Ryukyu tatami is once again attracting attention as a flooring material that creates a modern look for a traditional Japanese style residence. Shichitoui is difficult to harvest by machine as it grows dense, so it is done by hand. In addition, the tatami mats are also made entirely by hand, making it a truly high premium product. The hard work results as a powerful and pleasant green fragrant aroma that reminds us of the beautiful nature and culture of Japan.
