Tea room tatami

Tatami is the traditional flooring of Japanese tea rooms, made of rice straw and rush grass matting, essential for the tea ceremony.

About this subject

Tatami is a fundamental element of traditional Japanese architecture, especially in tea rooms (chashitsu). It consists of a core of compressed rice straw covered by a woven mat of rush grass (igusa). This natural composition provides thermal insulation, cushioning, and a characteristic aroma that contributes to the serene atmosphere of the space.

In the tea ceremony, tatami is not merely a floor but a stage for ritualistic interaction. The standard size of a tatami mat is approximately 1.82 m by 0.91 m, varying slightly by region. Room area is measured in number of tatami, for example, a typical tea room has four and a half mats. This standardization influences the design of the entire space, from the position of the tokonoma (alcove) to the arrangement of utensils.

Historically, tatami emerged during the Heian period (794, 1185), initially used only by the nobility. Over time, its use spread to temples and tea houses, becoming a symbol of refinement and simplicity. Artisan production requires great skill: rush fibers are sun-dried, dyed, and hand-woven. A high-quality tatami can last for decades, though the surface needs periodic replacement.

Interestingly, tatami also carries spiritual meaning. In the chashitsu, the edges of tatami are often bordered with black or brown cloth, and the number of folds in the border can indicate the lineage of the tea school. Additionally, stepping on tatami with shoes is considered disrespectful, as the floor is treated as a sacred surface.
