The core material of tatami is fiberboard.
The interior of the mats is made using fiber board.
At present, in Japan, mats that are made using straws carry a high
possibility of being defected due to mites or molds. As a result, the
material has long become obsolete in the country.
When rice straw tatami mats are exported, there is the issue of
quarantine, so our suggestion would be fiber board tatami mats.

Frequently asked questions about the use of tatami
We completely understand your concern about the fiberboard core feeling too stiff—like regular hardwood.
However, please rest assured that we insert a cushioning layer between the fiberboard core and the tatami surface (tatami-omote).
This added layer significantly softens the surface, providing a springy, gentle feel that is surprisingly close to the comfort of traditional rice straw tatami.
