Tea room tatami

Tatami mats are the traditional flooring of Japanese tea rooms, carrying centuries of history and cultural meaning in the tea ceremony.

About this subject

Tatami is a traditional Japanese mat made from compressed rice straw and covered with woven rush grass (igusa). Its origins date back to the Heian period (794-1185), when it was used as seating for the nobility. With the development of chanoyu (tea ceremony) in the 16th century, tatami became the essential flooring of tea rooms (chashitsu), defining the ritual space.

In a typical tea room, the number of tatami mats ranges from 4.5 to 8, following standardized proportions. A tatami mat measures approximately 1.91 m by 0.96 m, though dimensions can vary by region in Japan. The orientation of the mats is carefully planned to create harmony and flow during the ceremony. Additionally, the edges of the tatami (heri) are often silk with patterns indicating the season or the tea school's style.

Artisanal production of tatami involves layers of compressed straw hand-stitched together, covered with rush mat. Maintenance includes airing and replacing the cover every few years. Tatami is not just flooring: it determines posture, movement, and aesthetics of the tea ritual. Sitting correctly on the tatami is a key part of etiquette, and the sound of feet sliding on it contributes to the meditative atmosphere.

Interestingly, tatami also influenced Japanese architecture, with room dimensions often measured by the number of mats. Globally, tatami has become a symbol of minimalist design and Japanese culture, used in meditation and yoga spaces worldwide.
