Tea room tatami

Tatami mats are essential elements in Japanese tea rooms, made of rice straw and reed, shaping the ceremonial space.

About this subject

The tatami mat, or tatami, is a traditional Japanese flooring made of compressed rice straw covered with woven rush grass (igusa). Its handcrafted production dates back to the Heian period (794-1185), when it was used exclusively by the nobility. In a tea room (chashitsu), the tatami is not merely flooring: it defines the layout and etiquette. The number of mats indicates the room size, a standard tea room has four and a half mats (yojōhan). Their arrangement follows strict rules, such as the placement of the tokonoma (alcove) and the area for guests. The tatami also influences the sensory experience: the soft texture underfoot, the scent of rush grass, and the sound when walking. During the tea ceremony, movements are adjusted to the floor, and each step carries meaning. Moreover, tatami mats are recyclable and durable, lasting decades with proper care. The natural green of igusa turns golden over time, valued in wabi-sabi aesthetics. Interestingly, the word tatami comes from the verb tatamu, meaning 'to fold,' referring to the practice of folding mats for storage. Today, tatami symbolizes hospitality and tradition in Japan.
