Japanese Tatami & Goza Mats
Genuine Japanese Tatami Mats
Tatami are traditional Japanese floor mats made from rice straw and a woven sea rush (igusa) surface, bordered by brocade or plain cloth. Our mats are made using traditional methods — the underside of each mat is lined with igusa off-cuts or igusa unsuitable for the top of the mat rather than a synthetic backing, reducing the use of plastics in the mat's core construction.
It's important to know that tatami mats are not designed to be used as a rug or loose floor covering — in Japan, tatami is wall-to-wall flooring, fitted edge-to-edge to cover an entire room. If you're after the look and feel of tatami as a rug sitting on top of an existing floor, our Goza mats are the better choice. If you do choose tatami, we strongly recommend building a simple frame or setting the mats into a recessed floor cavity. A frame locks the mats in place so they don't shift or separate, protects the edges from early wear and tear, and hides the edge construction stitching — which, in Japan, is never left exposed.
Dimensions and Use
- Our standard full mats measure 180 x 90 x 5cm.
- Japanese room sizes are typically measured by the number of tatami mats (e.g. a traditional tea room is 4½ mats).
- For a flush finish in non-standard rooms, mats can be placed centrally surrounded by floating floorboards, or in any location with one of our wooden frames.
- We can supply custom-made mats to whatever size or shape you require.
- We also supply bed-sized tatami to complement our Japanese futons.
Quality and Compliance
- All materials are cleaned and disinfected without harmful chemicals, meeting strict Domestic & International standards.
- Sourced from Kumamoto (South-west Japan).
- The straw is oven-dried at 85°C for 8 hours to denature seeds/pathogens. This complies with Quarantine's import regulations and requires no further treatment (fumigation). An essential difference between Japanese straw and cheap Asian straw is that, in Japan, it is illegal to use untreated human waste to fertilise food crops.
- The underside of each mat is lined with igusa off-cuts, or igusa not suitable for the top surface, instead of a synthetic backing, which reduces the amount of plastic in the mat.
- Our supplier's modernised kiln reduces water content from 15% to 10%, making the mats more mould resistant and lighter without compromising quality.
