Kohin Japanese-made Moisture-proof Sheet for Under Tatami Mats, "For 8 Tatami Mats," Approximately 1m Wide X 3.8m Long X 4 Sheets Included.

This moisture-proof sheet can be used under tatami mats. Use it between tatami mats and floorboards or concrete floors. It can also be used on the ground below or on concrete foundations. It effectively blocks moisture rising from below. It's convenient for renovations and DIY projects. Cut it to size with scissors or a utility knife, but be sure to overlap it by about 15cm when installing. For best results, tuck the excess material up to the sides. If you're concerned about misalignment, use masking tape.
