DIY Tatami Mat Kit – Make Your Own Japanese Tatami

Our DIY tatami kit lets you make an authentic Japanese tatami mat at home. We make the tatami surface sheet (goza) with the border (heri) in our Tokyo workshop. You add a plywood core and fix it with a staple gun. No sewing is needed.

How to make a tatami mat with our kit

  1. Cut the plywood core 2 mm narrower and 3 mm shorter than the finished size (for example 898 x 1797 mm for a 900 x 1800 mm mat). Add fleece on top if you want a softer mat.
  2. Lay the tatami surface (goza) on your work table and fold the border along the sewn line on both sides.
  3. Turn the goza over and place the plywood on it. The goza extends about 15 cm beyond the plywood at each end.
  4. Fold one end over and staple it to the back of the plywood. Tap the staples flat with a hammer.
  5. Pull the goza tight toward the other end and staple along the edge every 3 cm. Do not staple the border itself.
  6. Fold the border inward at the four corners and staple them.
  7. If small wrinkles appear, smooth them with a towel and a steam iron. Keep the iron moving and never touch the border directly: it is nylon and melts.
