Tatami is a traditional Japanese flooring material made from rice straw and covered with woven rush grass. It is typically rectangular in shape and comes in various sizes, with the standard size being about 90 cm by 180 cm. Tatami mats are known for their unique texture and natural insulation properties, making them comfortable to walk on and sit upon. In Japanese culture, tatami is often used in tea rooms and traditional homes, where it contributes to a serene and minimalist aesthetic. The mats are usually arranged in a specific layout, and rooms are often measured in terms of the number of tatami mats they can accommodate.
