Since the IGUSA tatami mat series is made of rush, the mats can become moldy if used in basements, areas with high humidity (such as mountainous or coastal districts), or rooms that are not used very much, are generally closed, and have poor ventilation.
There is no need for worry about mold growth with the TOKYO and ZEN tatami mat series.
