Tatami houses are traditional Japanese homes characterized by their use of tatami mats, which are made from rice straw and covered with woven rush grass. These mats serve as flooring and provide a unique aesthetic and comfort. The layout of tatami houses often includes sliding doors called fusuma, which allow for flexible room arrangements and a seamless connection with nature. In addition to tatami mats, these houses typically feature wooden structures and large windows that invite natural light. The design emphasizes simplicity and minimalism, reflecting the principles of Zen philosophy. Tatami houses are not only functional but also embody a deep cultural heritage in Japan.
