I introduce Japanese traditional flooring "TATAMI". Recently, almost Japanese don't use it for new house. We don't like this tradition style. Because it have many demerit. The mites living inside the new TATAMI. Japan have many rain become high humidity. That's why mites and termites born prenty. And TATAMI needs change sometimes because it's became damage. It's made by 100% natural rice strow and rush. But we don't change it because high costly for normal society. I recommend TATAMI If you living dry area. The TATAMI merit is just better soft-cushion. You can sleep well thin mattress. Recently almost Japanese using bed but we also slept on the TATAMI floor. It have very nice scent.
